WhatsAppعرض المزيدHeap leaching is successfully used to extract gold, silver, copper, nickel, and uranium. The largest heap leach for gold is at the Yanacocha mine in Peru, second only to Veladero in Argentina. Heap leaching is used in tandem with electrowinning, for copper extraction; approximately 16% of the world''s total copper production is extracted in this way.

WhatsAppعرض المزيدCopper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
WhatsAppعرض المزيدCopper leaching is currently carried out in sulphuric acid media, Australia pioneered the application of this technology (Barter et al., 2001) by running a 40 m 3 /h .
WhatsAppعرض المزيدTwo proposals for the In Situ Leaching (ISL) of uranium are currently being considered in Australia. Both the deposits, Beverley and Honeymoon, are in the east of South Australia, Beverley is 520 kilometres north of Adelaide and Honeymoon is 75 kilometres directly northwest of Broken Hill.
WhatsAppعرض المزيدThe listed Australianbased nickel sulphide explorer and producer, Western Areas, took over the BioHeap® business developed by Pacific Ore (Australia) Pty Ltd in 2009. BioHeap® is an internationally patented bacterial leaching technology that uses proprietary microbial cultures to leach or ''liberate'' valuable metals from sulphide ores, and provides amenability, column and pilot testing
