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 60s.
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 (% 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 licensewhich are the best solutions for reducing the minechemistry . . pure copper may be produced by the reaction of copper (i) sulfide with oxygen gas as follows cu2s (s) + o2 (g) _ 2cu (s) + so2 (g) if the reaction of 0.540 kg of copper (i) sulfide with excess oxygen produces 0.0 kg of copper. you can view
