The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides ().Chalcocite (Cu 2 S) is the main copper sulphide mineral mined at bioleaching operations. Some of the chalcocite heap operations began as oxide (chemical) leach operations and were converted to bioleach
Techniques being explored for extracting lithium from clays include water disaggregation, hydrothermal treatment, acid leaching, acid baking water leaching, alkaline roasting water leaching, sulfate roasting water leaching, chloride roasting water leaching, and multiple reagent roasting water leaching.

Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical
This KS3 education resource looks at copper mining, extraction and pyroprocessing of sulfide ores.
An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The grade or concentration of an ore
