Had to make a few amendments A reading from ancient America Donald J. McMahon Symbologist/Researcher on the missing copper from Michigan. was there an ancient prehistoric PreDeluvian worldwide culture existing? People like Columbus were useful fools used as pawns, I never understood how it is Columbus gets the title of the one who discovered America when he didn't even land there, he landed way south It's not like he discovered Virginia or New York. He didn't even land in the US. Mainstream historians, archeology, geology All of the-ology's are in line with the church still. when you put them together it spells theology! Music from Doug Maxwell/Media right productions.video source material from http://ancientamerica.com/missing-pre... and Science frontiers - http://www.science-frontiers.com/cat-... Also music from Les Hayden" Not Really" I can no longer find it NOTE: When I mention the singling out the first "White man" to see Michigan copper, What it should have maybe been was the first Spaniard to see Michigan copper.Would he then represent all Spaniards? I would think not Or European man one can not clump people according to what shade of brown they are.Have you ever seen the experiment a teacher did with her students where each day she would designate a certain eye color that was to be ostracized for the day and right away the kids saw the schism of it all, for example, today all kids except those with blue eyes get to enjoy ice cream while blue-eyed kids must watch the others eat it something like that, I heard a wise person once say if you hate something you will come back in the next life as that what you hated, and I think that is a very good approach to take whether true or not . Just my thoughts on that, to be that way but it just continues Mike Wallace asked The actor Morgan Freeman how should we deal with it and he replied " Just stop talking about" I liked that answer.

"Prehistoric Alien Mines" Found On Lake Superior?

Patreon: https://www.patreon.com/MysteryHistory Facebook: https://www.facebook.com/MysteryHistoryBook/ Lake Superior, the largest of the north American Great Lakes, it is also the largest freshwater lake in the world by surface area. Believe to have first been inhabited 10,000 years ago after the retreat of the last Ice Age However, there exists copper mines upon many of the lakes islands, which many researchers have concluded to be prehistoric. A sophisticated array of tunnels litter the islands, or more specifically all of north America. Scarred by ancient mine pits as deep as 150 feet. Carbon-14 testing of wood remains found in sockets of copper artefacts indicated that they are at least 5700 years old. Although many have suggested that artefacts and evidence at some sites, has suggested a date far older than what has been put forward. For example, some investigators believe that the mines were not even built by humans, but are the remains of a sophisticated mining operation that was once undertaken by alien visitors many thousands of years ago. Similar in scale to the ancient Carolina Mica mines, Mica being a material which we use in electrical components. The ancient copper mines on Superiors isle royale for example, although predictable disputed, produced over 750,000 tons of copper for a sophisticated group of ancient, mystery miners. Findings published in 1961 within, “Prehistoric Copper Mining in the Lake Superior Region, by Roy Drier and Joseph Du Temple. It must be noted that all of these pregistoric mines show evidence of being abruptly abandoned, whether this is evidence of the death of an unknown king or queen, or evidence for catastrophe is unknown, all along lake shore are vestiges of this once highly successful, ancient operation. The most astonishing of remnants catalogued publicly, has to be the enormous lump of pure copper, found in 1771, near the bank of the Ontonagon river. In 1945 it was floated down river on a raft by a james k paul, and was eventually appropriated by an agent of the united states government, it was then shipped to Detroit and on to Washington, where it eventually slipped into the bowels of the Smithsonian. Known as the Ontonagon Boulder it weighs 3,708 pounds, it was apparently well known to Native Americans. According to the Keweenaw Bay Indian Community, the boulder was used by tribe members to make offerings to its “manitou” or spirit, to seek improvement in their health and well-being. Just how old is the Ontonagon Boulder? Or indeed the mine in which it came from? Although many would like you to believe the mines are less than 5000 years of age, we think many factors surrounding them, suggest they are far older than that.

Copper Through The Ages - The History Of Copper - History TV
 
42:36
Copper Through The Ages - The History Of Copper - History TV Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. It is used as a conductor of heat and electricity, as a building material and as a constituent of various metal alloys, such as Sterling silver used in jewelry, cupronickel used to make marine hardware and coins and constantan used in strain gauges and thermocouples for temperature measurement. Copper is found as a pure metal in nature, and this was the first source of the metal to be used by humans, ca. 8,000 BC. It was the first metal to be smelted from its ore, ca. 5,000 BC, the first metal to be cast into a shape in a mold, ca. 4,000 BC and the first metal to be purposefully alloyed with another metal, tin, to create bronze, ca. 3,500 BC.[3] In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal, from aes сyprium (metal of Cyprus), later corrupted to сuprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived.[4] The commonly encountered compounds are copper(II) salts, which often impart blue or green colors to such minerals as azurite, malachite, and turquoise, and have been used widely and historically as pigments. Architectural structures built with copper (usually roofing elements) corrode to give green verdigris (or patina). Decorative art prominently features copper, both in the elemental metal and in compounds as pigments. Copper compounds are also used as bacteriostatic agents, fungicides, and wood preservatives. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c oxidase. In molluscs and crustacea copper is a constituent of the blood pigment hemocyanin, replaced by the iron-complexed hemoglobin in fish and other vertebrates. In humans, copper is found mainly in the liver, muscle, and bone.[5] The adult body contains between 1.4 and 2.1 mg of copper per kilogram of body weight. Hence a healthy human weighing 60 kilogram contains approximately 0.1g of copper. However, this small amount is essential to the overall human well-being.

Out of Place Artifacts, The Michigan Tablets
 
01:40:40
Alex Koritz shares out of place artifacts with the AHRF, the controversial history of the thousands of ancient writings on tablets that his family once owned. These anceint tablets were found in North America by the tens of thousands, over a period that covered hundreds of years. Main stream academia not wanting to admit that there was inter continental travel between the old and new world before columbus declared them a fraud. Because of the old world languages contained on them and because of some of the biblical scenes some of them contained they were immediately dismissed. New evidences have been found to support the validity of these tablets. Glen Beck did an entire show on these artifacts in support of there authenticity. Alex shares his families insight on them and how you can view them for your self in person to see this amazing collection that is not known about.

The Michigan Mine Mystery (See Description Below)
 
04:49
Please give me your opinion on this mystery in the comments section… In the video, I identify this abandoned mine as the Michigan Mine. I did so because this is how it was identified to me by a very knowledgeable local historian (who was herself advised by some of the mining old timers that were born and died in this area). However, after our visit, subsequent research leads me to believe that this may actually be the Nip & Tuck Company [Mine]. The Michigan Mine bordered the Nip & Tuck and the Nip & Tuck actually purchased the Michigan Mine in 1869 in order to obtain control of their ground. So, it is understandable that the names could be confused or even used interchangeably. However, I want to be as precise as possible with this stuff… So, tell me what you think: The Michigan Mine and the Nip & Tuck were both placer claims. However, the Michigan Mine was an adit driven back 3,000 feet into the Gibsonville Ridge. The Nip & Tuck Mine is described as being situated where a tunnel would have been too great of an expense to run and so a shaft was driven down to a depth of 230 feet. The work in this shaft was aided by a large steam engine situated next to the mine shaft. Further, there is a description of an area below the mine being used for washing the gravel being hauled out. Now, tell me that what you see in the video doesn’t look a lot more like the description of the Nip & Tuck instead of the Michigan Mine? There are documents indicating that 40 men worked at the Nip & Tuck Mine in 1870. And, although not a trace remains, there was supposedly an engine house built over the steam engine in addition to an abundance of skip cars and flumes on the site. The Nip & Tuck was apparently a profitable mine as an 1871 issue of Mining & Scientific Press describes the mine as returning a profit of 100% over expenses the previous autumn. The Michigan Mine, at its peak, apparently had 15 men working and even had a blacksmith living on site with his family. ***** All of these videos are uploaded in HD, so adjust those settings to ramp up the quality! It really does make a difference… You can click here for the full playlist of abandoned mines: https://goo.gl/TEKq9L If you like these videos on exploring abandoned mines, please subscribe! https://goo.gl/yjPxH1 Thanks for watching! ***** Growing up in California’s “Gold Rush Country” made it easy to take all of the history around us for granted. However, abandoned mine sites have a lot working against them – nature, vandals, scrappers and various government agencies… The old prospectors and miners that used to roam our lonely mountains and toil away deep underground are disappearing quickly as well. These losses finally caught our attention and we felt compelled to make an effort to document as many of the ghost towns and abandoned mines that we could before that niche of our history is gone forever. But, guess what? We have fun doing it! This is exploring history firsthand – bushwhacking down steep canyons and over rough mountains, figuring out the techniques the miners used and the equipment they worked with, seeing the innovations they came up with, discovering lost mines that no one has been in for a hundred years, wandering through ghost towns where the only sound is the wind... These journeys allow a feeling of connection to a time when the world was a very different place. And I’d love to think that in some small way we are paying tribute to those hardy miners that worked these mines before we were even born. So, yes, in short, we are adit addicts… I hope you’ll join us on these adventures! #ExploringAbandonedMines #MineExploring #AbandonedMines

Abandoned Dredge and Copper Mine:  Inside Look!
 
11:31
Exploring some old Copper Mining ruins (https://amzn.to/2KaB6dk) and a shored 100+ year old Dredge outside the towns of Houghton and Hancock, Upper Michigan, known as the Quincy Mine area. **Copper County Quincy Mine Field Guide: https://amzn.to/2KaB6dk The building was a drop point and grinding/crushing facility for the raw mining material (copper). Once it was crushed, they would use chemicals to get the copper sulfides out of the rock. From there it went across the street to the smelter and then shipped out down the channel. If you look closely in the building you will notice the concrete is actually "bleeding" and creating stalactites and stalagmites on the roof and floor. I am not sure if this is natural erosion found with old concrete structures or a possible side effect from using the mining chemicals in this building. You could definitely tell it was contributing to the decay of the building supports/foundations. Most of the concrete in these areas are crumbling like they are made of paper-mache. The Dredge was old, crumbling, and very difficult to get in. Although technically climbing and exploring the Dredge is not permitted due to safety, its pretty cool to climb around a decaying structure this large from 100 years ago. Just do so at your own Risk :) The technology in the Dredge is old, but still very impressive! Most of the Smelting building (or what I believe is the smelter) is gone. The only thing that remains is the smoke stack and coal hopper. Both of which are pretty impressive. The coal hopper even had some coal left in it. **Copper County Explorer Quincy Field Guide: https://amzn.to/2KaB6dk --PLAYLIST on all Sights & Adventures: https://goo.gl/8n1VKi Thanks for Watching, and don’t forget to Like, Share, and Subscribe!

Quincy Mine Tour
 
06:13
The Quincy Mine was founded in 1846 by the merger of the Northwest Mining Company and the Portage Mining Company. Due to poor communication between government offices, these two speculative mining companies had purchased the same tracts of land during the mining rush of the early 1840s.[7] The directors met and decided to merge, with significant investment coming from Massachusetts (the town of Quincy, Massachusetts lent the mine its name). While many other copper mines were founded at the same time, the Quincy Mine became the most successful of the 1840s-era mines, and was the country's leading copper-producing mine from 1863 (when it exceeded the production of the Minesota Mine) through 1867 (after which it was exceeded by the Calumet and Hecla).[8] The mine was the first Michigan copper mine to switch from fissure mining to amygdaloid mining, when the recently discovered Pewabic amygdaloid lode was found to cross Quincy property in 1856.[9] High-grade fissure veins contained large, pure masses of copper, but the masses could take days or even months to extract, at high cost. Amygdaloid mining consisted of extracting lower-grade strataform orebodies in the "amygdaloid zones," the upper portions of basalt lava flows. Rock bearing small pockets of copper could be blasted out immediately and processed elsewhere at much lower cost. Amygdaloid mining proved much more productive than fissure mining, and the size and richness of the Pewabic lode in particular allowed the Quincy to produce profits for 53 consecutive years. The Quincy company expanded laterally along the lode by buying out adjacent properties. The company bought the Pewabic mine in 1891, the Mesnard and the Pontiac in 1897, and the Franklin mine in 1908.[10] This helped the mine survive longer than almost all other Keweenaw copper mining companies, except the Calumet and Hecla Mining Company and the Copper Range Company. To attract a better class of worker, the Quincy Mining Company built and maintained housing for the workers. Over the course of operations, the types of housing ranged from simple tents in the early days, to complete three story houses shortly before the mine's shutdown. The executives on the east coast wanted to build more elaborate and fancy homes with amenities such as electricity and running water. However, the on-site managers didn't think it was necessary for the miners to have such high-class dwellings. But the east coast executives realized that if they offered nicer homes to the workers, the miners were more likely to stay, raise families, and be less likely to leave the area or transfer to another mining company. This strategy proved effective and helped the Quincy Mining Company retain its status as one of the premier mining companies in the region. The Quincy Mining Company closed operations (but did not dissolve) in 1931 due to low copper prices.[11] During World War II, the mines re-opened due to increased copper demand. When the government stopped supporting copper prices after the war, the mines quickly closed for good.

How Copper is Mined and Refined: "A Story Of Copper" 1951 US Bureau of Mines

Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Copper_extraction_techniques Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Copper extraction techniques refers to the methods for obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). To do this, the ore is crushed. Then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it undergoes various refining processes, the final one being electrolysis. For economic and environmental reasons, many of the byproducts of extraction are reclaimed. Sulfur dioxide gas, for example, is captured and turned into sulfuric acid — which is then used in the extraction process... History The earliest evidence of cold-hammering of native copper comes from the excavation at Çaÿonü Tepesi in eastern Anatolia. The radiocarbon date is 7250 ± 250 BCE. Among the various items considered to be votive or amulets there was one that looked like a fishhook and one like an awl. An archaeological site in southeastern Europe (Serbia) contains the oldest securely dated evidence of copper making at high temperature, from 7,000 years ago. The find in June 2010 extends the known record of copper smelting by about 500 years, and suggests that copper smelting may have been invented in separate parts of Asia and Europe at that time rather than spreading from a single source. Copper smelting technology gave rise to the Copper Age and then the Bronze Age. Concentration Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock. The first stage of any process within a metallurgical treatment circuit is accurate grinding or comminution, where the rock is crushed to produce small particles... Subsequent steps depend on the nature of the ore containing the copper. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores, both secondary (supergene) and primary (hypogene), froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergene native copper, this mineral can be recovered by a simple gravity circuit... Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production)... The copper is refined by electrolysis. The anodes cast from processed blister copper are placed into an aqueous solution of 3–4% copper sulfate and 10–16% sulfuric acid. Cathodes are thin rolled sheets of highly pure copper or, more commonly these days, reusable stainless steel starting sheets (as in the IsaKidd process). A potential of only 0.2–0.4 volts is required for the process to commence. At the anode, copper and less noble metals dissolve. More noble metals such as silver, gold, selenium, and tellurium settle to the bottom of the cell as anode slime, which forms a salable byproduct. Copper(II) ions migrate through the electrolyte to the cathode. At the cathode, copper metal plates out, but less noble constituents such as arsenic and zinc remain in solution unless a higher voltage is used. The reactions are: At the anode: Cu(s) → Cu2+(aq) + 2e− At the cathode: Cu2+(aq) + 2e− → Cu(s)...
