Heap Leaching Oxide and Sulfide Copper Ores

Heap leaching is a simple means of recovering copper from oxide and oxide-sulfide ores. Although this method requires relatively low capital investment, it suffers from low copper recoveries and relatively high acid consumption. The objectives of this study were (1) to determine what factors influence these shortcomings, and (2) to establish a

Heap Mining Efficiently Leaches Lower Grade Gold from S

What is an Economical Heap Leach Mine Today? As a rule of thumb, one gram per ton of ore can make a profitable heap leach mine. At a 75% gold recovery, it takes 41 tons of ore on the pad to recover one ounce of gold. However, all the material in the mine is not ore. Most mines will have 2-3 tons of waste material to 1 ton of ore.
