Recovery of Copper by Solution Mining Methods

a weak sulfuric acid solution Copper within the rock is dissolved in the acidic solutions as it percolates downward to the water table, where reducing conditions ie oxygen-poor environment promote copper precipitation as chalcocite Cu 2 S Over time, this action forms an oxidized zone ie leached cap above a thick, copper-rich blanket-...
