  • Heap leaching

    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 reseparate 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

    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 .

    Jul 03, 20150183;32;Cyanidation is not used to extract large size gold nuggets from ore because the process is deemed too slow and is not cost effective. In mining operations that contain larger, freemilling type gold deposits, stamping and traditional gravity separation methods are more effective.

    The first cyanidation plant in the world was established close to Waihi, at the Crown Mine at Karangahake, in 1889. By 1892 there were six cyanide plants on the Ohinemuri Goldfield, plus others at Thames and Coromandel. The process was a great success, as the recovery of gold improved from 4050% to 8595%.
