copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. the smelters were initially located near the mines to minimize the cost of transport. this avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the coppercontaining minerals. however, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first.
initial concentration techniques included handsorting and gravity concentration. they resulted in high losses of copper. consequently, the development of the froth flotation process was a major step forward in mineral processing. it made possible the development of the giant bingham canyon mine in utah.
in the twentieth century, most ores were concentrated before smelting. smelting was initially undertaken using sinter plants and blast furnaces, or with roasters and reverberatory furnaces. roasting and reverberatory furnace smelting dominated primary copper production until the 1960s.
the roasting process is generally undertaken in combination with reverberatory furnaces. in the roaster, the copper concentrate is partially oxidised to produce "calcine" and sulfur dioxide gas. the stoichiometry of the reaction which occurs is
roasting generally leaves more sulfur in the calcined product (15% in the case of the roaster at mount isa mines) than a sinter plant leaves in the sintered product (about 7% in the case of the electrolytic refini · text under ccbysa licensecopper recovery using leach/solvent extractionthe first process, vat leaching of highgrade copper oxide ore followed by ew of copper from the leach solution, produced low quality copper cathode at relatively high cost. in 1968 the tonnage of highgrade oxide ores was decreasing and vat leaching was on the decline. the second processcopper production how is copper made? thoughtcosulfide copper oresoxide copper oresinsitu leachingproducing copper from recycled sourcesvirtually all sulfidetype copper ores, including chalcocite (cu2s), chalcopyrite (cufes2) and covellite (cus), are treated by smelting. after crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic. the mixture is then bathed in water along with a foaming agent, which encourages frothing.see more on thoughtcoestimated reading time 7 mins
