Agglomeration Drums in the Heap Leaching Process

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 appliions growing all the time.. While this process has proven to be efficient, often chosen for its costeffectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.
