Heap Leaching Oxide and Sulfide Copper Ores

Leaching studies were conducted on coarse oxide and sulfide copper ores in small laboratory columns and in large concrete columns in the field. These studies were designed to determine the influence of various stone and physical parameters on heap leaching and to establish a correlation between laboratory and field testing.

World ore deposits of copper are becoming lower in head grade with copper sulphides, particularly chalcopyrite being the predominant mineralogy [1]. Copper is typically recovered from these low-grade ore by means of heap leaching. Heap leaching involves trickling a leach solution though a bed of ore to extract target metals. The bed of ore (or

Heap leaching a stack of gold MiningFeeds

Heap leaching is used to extract gold, copper, silver, uranium, and iodine. This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s, and then by several gold mines in the western parts of the US a few years later. Since then, heap leaching has been adopted successfully by many mines across the world. Heap leaching occurs after the mining and crushing
