How much metal does the ore contain? « World Ocean Review

In most cases copper ores contain between 0.6 and 1 per cent of copper. Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper. In the case of platinum the yield is much lower: 1 tonne of ore usually contains between 3 and 6 grams of platinum. Nonetheless it is still worthwhile mining because the platinum price is high.


Copper Ore to High-Purity Copper, and the Quantification

Jul 22, 2014· To obtain high-purity copper, the ore is concentrated for processing by crushing and grinding it into a powder containing 20-30% copper. The concentrates are smelted and the sulfide minerals are partially oxidized to yield a layer of matte, a mix of copper-iron sulfide and slag, and an upper layer of waste.


Some observations on copper yields and ore grades

Some observations on copper yields and ore grades. Author links open the observed decline in the average yield of copper ore milled has come from a combination of the exhaustion of other types of copper deposits with higher average grades than porphyry coppers and from the tendency, already noted, for head grades to fall towards a deposit's
