leaching process. The process can involve crushing the ore and then binding it, or the ore can be directly placed on the heap or leach dump, where the lixiviating solution percolates through the ore to release the copper ions into solution. If agglomeration is used the sulfuric acid starts to dissolve the copper from the minerals.

The heap leaching approach to ore beneficiation is a growing trend in the mining industry, with applicability to various metals outside of copper and gold. Agglomeration is a valuable tool in maximizing recovery during the heap leaching process.

Agglomeration of ore is a method which can be used to eliminate the migration of fi ne grained particles throughout a leach heap. Without agglomeration, fi ne ore particles are able to migration within the heap, clogging fl ow channels and producing large areas where access of the solution is poor.
