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.Virtually 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.
Tomra sorting solutions utilizes cutting-edge copper sorting technology to get results from copper mined sulphide and oxide deposits. our copper sorting technology treats feeds from both types of ores based on different physical properties at feed rates of up to 300t/h.
Mans found nearly 100 lens-shaped ore bodies in the rio tinto copper district. modern geologists have found only a few additional deposits, and almost all of rio tinto’s modern production has been from ore first discovered by the remans.3 at rio tinto, the remans mined the upper, ox-idized, part of the ore and collected the copper mining.Feb 20, 2017 the mine produces over 1.1 million tonnes of copper ore and in excess of 185,000 tonnes of copper concentrate per annum. the concentrate contains approximately 29 copper and is mining.Ore sorting has been an essential part of the upgrading process since time immemorial. bronze age miners would certainly have been highly selective in their approach to copper ores, using mineral color to choose between good material and waste.Nov 27, 2019 the company announced on march 29, 2019 that testing conducted at tomra sortings test center in hamburg, germany appeared to successfully separate copper ore  from waste rock based on sulphide mining.
