  • How diamond is made

    The actual mining of diamonds as an industry can be traced back to India to around 800 to 600 BC India was the only known source of the rocks for over a thousand years, until they were unearthed in Borneo around AD 600 During the Middle Ages, the diamond was overshadowed by some of the more colorful gems like the ruby and emerald...

  • How and why do we produce gold and copper ,

    mining engineering and metallurgy (mineral processing) are fascinating and require an in depth understanding of the best way to find, mine and process (extract) the payable minerals In general terms, when gold is the only payable mineral present (ie >98-99% of the value), we can process the ore on the mine site and create gold bars...

  • How Gold Is Refined: A Step

    The crude gold is melted and then treated with chloride This converts any foreign elements or minerals still in the gold into chloride, which will then naturally drift off the gold The result of this process is 995 percent pure gold The final step is to cast the gold into electrodes or ,...

  • Heap leaching

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ....

  • Boddington Mine

    The barren carbon product from the elution columns is transferred to the carbon reactivation plant before transfer back to the CIL train, and the gold solution transfers to the electrowinning circuit The final product from the eight-unit electrowinning circuit reports to the gold furnace for smelting...

  • Gold mining

    By-product gold mining Gold is also produced by mining in which it is not the principal product Large copper mines, such as the Bingham Canyon mine in Utah, often recover considerable amounts of gold and other metals along with copper Some sand and gravel pits, such as those around Denver, Colorado, may recover small amounts of gold in their ....

  • Mineral processing

    Dewatering is an important process in mineral processing The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue...

  • Gold extraction

    The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele, but it was not until the late 19th century, that an industrial process was developed The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore The gold ....
