Copper Ore Hydrometallurgy and Pressure LeachingCopper
Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficulttoconcentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electrowinning (EW). It can produce either copper cathode or copper sulphate crystal.

Copper Refining: From Ore to Market | INN
The copper is concentrated further by slurrying the ground ore with water and chemical reagents. In this process, air is blown through the mixture, and the copper floats to the top. The copper is then removed with a skimmer. At the end of this step, copper concentrations are typically between 24 and 40 percent.
