Production of cobalt from copper-cobalt ores on the African
网页2020年9月1日The ore from the Nchanga open pit contains pockets of ore with higher grades of cobalt, typically about 0.3% cobalt and 1.3% copper. This ore is processed in campaigns through the cobalt flotation circuit, which is illustrated schematically in Fig. 11. The concentrate typically contains about 16% copper and 4% cobalt.

Copper Ore an overview ScienceDirect Topics
网页Heap leaching of copper ores is widely practiced, particularly in North and South America, for the leaching of acid-soluble oxide minerals and secondary sulfides, such as chalcocite. The contribution to hydrometallurgical copper production by heap leaching is expected to continue, because this technology is relatively simple, robust, flexible, and low cost.
