 · The carbon-adsorption process has a degree of tolerance to copper in ores as discussed below and this process has largely overtaken the traditional gold cementation processes such as the Merrill–Crowe process, not because of greater tolerance to copper in pregnant solution, but because of the inherent advantages of the carbon-in-pulp (CIP)/carbon-in-leach (CIL) process over the traditional leach-filtration…

1.3 Flotation and subsequent processes (refractory ore processing) The flotation process is described in detail in chapter 3.3. Native gold, gold tellurides, and sulphides that contain finely disseminated gold can be floated and recovered in a concentrate. In gold metallurgy flotation is often used as a pre-enrichment process for refractory ores.

Dump leaching has mostly been applied to gold, silver, and copper ores, whereas heap leaching has been applied to many different minerals including copper, gold, silver, ura-nium, vanadium, zinc, nickel, and cobalt. However, as the principal applications are copper and precious metals, most of the following discussion will refer to these metals.

Dump and Heap Leaching

Dump and Heap Leaching

the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-tion-electrowinning, the basic methods of cop-per production have remained unchanged for 65 years.
