Copper Heap Leaching & SX-EW Slideshow - MineralsEd

A leaching solution of weak sulphuric acid is sprayed over the rock on the pad and allowed to percolate through to the base. As the solution passes through the heap, the copper-bearing mineral dissolves into solution. The copper-bearing solution accumulates in the collection pond and is piped to a nearby SX-EW plant for metal recovery. Leaching
