Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market. Carbonate concentrates are a relatively minor product produced from copper cementation plants, typically as the end-stage of a heap-leach operation.
Heap leaching is a tried and tested mining technique enabling the processing of different kinds of ores which could not otherwise be exploited under viable economic conditions. Modern day heap leaching, which has a relatively low level of energy consumption, is for example
Jun 09, 2017· The heap leaching technology has seen substantial growth over the past few decades, becoming a key process in mining; NAUE, a group specializing in geosynthetic liners, assesses that over 30% of copper and gold produced each year is beneficiated via heap leaching, up from only about 3% decades earlier.
