Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Two-stage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or ...

The SXEW facility has a production capacity of 56,000 tons per year of LME grade A copper cathodes. Overburden removal commenced in 1957 and ore production commenced in 1960. Our Toquepala operations utilize a conventional open-pit mining method to collect copper ore for further processing in our concentrator.
The Copper Crude Ore Bin next to the 270m Mount Isa Mines lead smelter stack now boasts a newly sheeted roof, which owners Glencore say should see out the life of the asset.
AVERAGE COPPER MINING GRADES CHILE VS WORLD 2005-2016 • Average Ore grades of the sulfide line have decreased similarly (27%), Chile and the World. • Ore grades of the oxides line in Chile are lower than the world average. • There is a depletion of oxidized resources in Chile, which will mean 66% lower production of SX-EW cathodes by 2027.

The ore sample used contained 2.03% Cu, 0.15% Co, and 3.73% S. The valuable minerals present were chrysocolla, chalcopyrite, and native copper. The gangue comprised pyrite, carbonate, calcite, and clay minerals. The ore (of a size up to −149 μm) was beneficiated using the sulphidisation and xanthate flotation method.
