Ultimate recovery of the target mineral can range from 30% of contained run-of-mine dump leaching sulfide copper ores to over 90% for the ores that are easiest to leach, some oxide gold ores. The essential questions to address during the process of the heap leaching are: • Can the investment of crushing the ore be justified by the potential increase in recovery and rate of recovery?•

In heap leaching the ore is usually heaped as it comes from the mine without any breaking on crushing treatment. Frequently, pieces of rock 5 or 6 feet across a face are found in the heaps. Solution is added to the ore at the surface and seeps downward by gravity and is collected in a solution sump.

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.

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.
