The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. the oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.Innovations: introduction to copper: mining & extractionVirtually all the ore used by the ancients was handpicked with only the most worthwhile material being taken. originally it was probably smelted by the sumerians in shallow pits using charcoal as the fuel. how they first derived the necessary draught to raise the temperature sufficiently to melt the ore is still a matter of speculation, but it mining.Dec 11, 2020 the one using fast on-line xrf sensor at primary crushed ore to detect amount of waste, which can be separated before the mill horizon 2020 iterams project, and the other to estimate sorting potential already during exploration stage by analysing drill cores or drill cuttings accurately and frequently to get practical results for real sorting potential. in both customer cases also economical mining.
