Acid Leaching - Copper Ore Treatment Method
The method for recovery of copper from leach solutions by precipitation with iron has been known for many years, being reported in use by Rio Tinto Mines in Spain as early as 1752. Scrap iron, detinned cans and sponge iron have been used depending on cost and availability. Labor costs involved in the use of scrap iron and cans are usually higher than with the use of sponge iron.

Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production). Davenport, et al, noted in 2002 that even then 80% of global primary copper production was from copper–iron–sulfur minerals and that the vast majority of these were treated by smelting. Copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. The smelters

Producing Copper Nature's Way: BioleachingSummaryExamples of Current Industrial Bioleaching OperationsBackgroundChemistry of BioleachingMicrobiology of BioleachingLeaching MethodCostsResearchConclusionsBioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid leaching wherein only oxidized mi在copper.org上查看更多信息
