DEPENDENCE OF MINE REVENUE ON THE GRADE OF COPPER

Dependence of mine revenue on the grade of copper concentrate 549 Parameter A in formula (3) can be determined experimentally by using a series of observations { } and {β} or by using the hypothesis that it will progress as in Fig. 3a. Then, by knowing the current value and β parameter A can be adjusted iteratively for compliance of the calculated result with the measured one.

The World's 20 Largest Copper Mines - ThoughtCo

Nov 25, 2019  The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the world's total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The U.S. makes the cut, as well, with two mines among the top 20. Copper is expensive to mine and refine.

Batu Hijau mine - Wikipedia

Ore from the mine has an average copper grade of 0.49% and an average gold grade of 0.39g/t. Crushed ore is further reduced in size by Semi-Autogenous Grinding and ball mills. Once milled it is sent through a flotation circuit which produces a concentrate with a grade of 32% copper and 19.9g/t gold. The mill realizes a copper recovery of 89%.
