Copper Heap Leaching SX-EW Slideshow - MineralsEd

Heap leaching SX-EW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond.

Agglomeration Drums in the Heap Leaching Process

Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with applications growing all the time.. While this process has proven to be efficient, often chosen for its cost-effectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.
