Copper Concentrate is created by purifying Crushed Copper Ore in one of two different crafting stations. The crafting stations come with different ratios, labor cost and time cost. The process to make Copper Concentrate also gives a byproduct of Wet Tailings which is a pollutant. Copper Concentrate is the last step in the production line …

Copper Flotation Process Summary. ... The concentrate can then be reground and refloated with the production of a high-grade copper concentrate together with a low- grade pyritic tailing suitable for return to the roughing circuit. This method is likely to be less costly than one involving the fine grinding of the whole ore.

The final copper concentrate produced contains 25.1% copper with 86% recovery. The Mikheevskii MPE, producing 18 million t of porphyry copper ore per year (at a grade of 0.4% cop-per), applies the bulk-differential flowsheet and pro-duces copper and molybdenum concentrates. The flo-tation feed is the tertiary grinding overflow of 80% …

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.
