Copper extraction - Wikipedia

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically .

Apr 25, 2017 · How to Find the Percent of Concentration of Copper Sulfate in Copper Sulfate Pentahydrate. Therefore, Cu = 63.55 * 1 = 63.55 amu. The other atoms in the formula are S = 32.07 * 1 = 32.07 amu; O = 16.00 * 9 = 144.00 amu; and H = 1.01 * 10 = 10.10 amu. Combine these figures to get the formula weight: 63.55 + 32.07 + 144.00 + 10.10 = 249.72 amu.
