mining operations by leaching

Innovations in Copper Mining Extraction Producing

Heap leaching has the additional cost of mining and transporting to the leach pad. In some operations additional costs are incurred wherein the ROM is crushed and mixed with acid for agglomeration prior to being deposited in the heap. Because of this, as shown in Table 1, direct production costs vary with the grade of the material being leached. 26

3. Carbon In Leach (CIL) The carbon in leach process integrates leaching and carbon in pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.

Environmental Risks of Mining

Most underground mining operations increase sedimentation in nearby rivers through their use of hydraulic pumps and suction dredges; blasting with hydraulic pumps removes ecologically valuable topsoil containing seed banks, making it difficult for vegetation to recover (Miranda et al., 1998).

Heap leaching

Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re separates 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
