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 ....

What is the Cost of Mining Gold?

The bulk of silver production comes as a by-product of other metal mines, such as zinc, copper, or gold min Since silver is not the primary metal emerging from some of these mines, it faces supply crunches when other metal prices are low Silver supply is falling for three reasons: Declining mine production due to low base metal prices...

Part Four Competitiveness

Ore Grade The costs of mining and processing copper are more closely related to the gross tonnage of the ore than the net tonnage of copper in the ore5 A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore However, because the rich ore con-tains more copper, it requires less of these inputs...

Abstract

Typical appli­cations of SX-EW mills are for leach solutions from oxide or chalcocite dump, waste, or in situ copper or The cost equations are valid for ore tonnage capacities of 6,000 to 70,000 st/d Basic assumptions include an ore grade of 04% Cu and a recovery of 50%...
