Innovations: Copper: Technology Standards

The introduction of the flotation process in the late nineteenth century permitted the extraction of copper and other metals (including gold and silver) from lowgrade porphyry ores. Figure 1 illustrates the ore haulage from an early mine using small rail cars, whereas today's ore handling employs 200 to 300ton trucks and gigantic shovels ...

Gold extraction

Gold extraction

If the gold can not be concentrated for smelting, then it is leached by an aqueous solution: . The cyanide process is the industry standard.; Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience pregrobbing: the absorption by carbonaceous components which preferentially absorbs gold and goldcyanide complexes.
