Copper Ore Hydrometallurgy and Pressure .

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.

Sulfuric acid injection in copper heap leaching | .

Copper oxide ores are processed using aqueous solutions to extract and purify copper in three steps: Heap leaching is the use of percolating chemical solutions to leach out metals. Following mining, transporting and crushing to a consistent gravel-size, the ore is piled into a heap on top of an impenetrable layer on a slight slope.
