Click to chatHeap 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.
