coal gold agglomeration process

from its ores The Coal Gold Agglomeration CGA process was developed some years ago and has the advantage in that gold is recovered by a procedure which has little or no negative impact on the environment A gold ore containing liberated gold particles is contacted with coaloil agglomerates whereby the gold is recovered into the coaloil phase Get a Quote Send Message

Agglomeration Drums for Processing Gold Ore

The process of heap leaching extracts gold from ore by piling up crushed ore and applying a leaching agent to permeate through the pile separating the gold from the ore While this method has been used for decades with success it has been greatly improved by the addition of an agglomeration drum to the process before the heap

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 costeffectiveness the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum
