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 .

What is Placer Gold Mining?

2021/4/14Unlike hardrock mining, which extracts veins of precious minerals from solid rock, placer mining is the practice of separating heavily eroded minerals like gold from sand or gravel. The word placer is thought to have come from Catalan and Spanish, meaning a shoal or sand bar. The word entered the American vocabulary during the 1848 California
