2021-11-12  Chalcopyrite (CuFeS 2) is the most abundant copper sulfide and it accounts for 70% of the copper reserves in the world (Li et al., 2013). Conventionally, the pyrometallurgical process is primarily used to recover copper from chalcopyrite because chalcopyrite is a widely used refractory material for hydrometallurgical processes .

The removal of lead from chalcopyrite surfaces in relation ...

2021-9-1  In order to introduce lead ions to the mineral surfaces, chalcopyrite was ground in a tumbling mill with lead nitrate (as a proxy for 210 Pb) in a “contamination” step. This grind was performed in an 8.2 L (195 mm internal diameter, 274 mm internal height) tumbling mill at 50 wt% solids (50% mineral charge, 50% liquid by mass).

The World's 20 Largest Copper Mines - ThoughtCo

2019-11-25  Terence Bell. Updated November 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.

Recover Ultrafine Chalcopyrite by Flotation

2018-4-3  Pure Chalcopyrite. About 200 g of the pure chalcopyrite was ground in a rod mill with deionized water for 1 h. The ground slurry was wet-screened at 38-µm size. The plus 38-µm-size chalcopyrite was reground for another hour in the rod mill. The combined slurry was diluted to less than 3 pct solids with deionized water.

A Review on Novel Techniques for Chalcopyrite Ore

2012-1-1  Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.
