Heap leaching is the most important method of hydrometallurgical copper extraction. Heap leaching is used for treating oxide and lower-grade secondary sulfide ores that contain up to ∼2% Cu. The ore is crushed to a uniform particle size (typically 12–50 mm), often agglomerated, and then stacked on large flat-topped heaps in a controlled manner.. …

The heap was an accumulation of ore from an on-off heap leach formerly operated by a large international mining corporation, Billiton. Based on an evaluation of exploration drillholes into the heap, KCA was able to show that washing would mitigate an environmental problem (high residual cyanide) and recover significant amounts of gold …

At the same time, they're constantly on the lookout for suitable and cost-effective equipment and systems for every heap-leaching project. Understanding the time-rate-of-recovery dynamics in heap-leach operations is mandatory for analyzing the financial performance of any mining operation. It's also a must for the successful execution of a project.
