Agglomeration Drums in the Heap Leaching Process

A Look at The Heap Leaching ProcessWhat Is An Agglomeration Drum?ConclusionHeap leaching is a hydrometallurgical approach to ore beneficiation. Upon removal from the ground, mined ore is sent through a crusher to break the ore down into fines. The ore fines are then heaped, into a large pile. This mound is then irrigated with a special solution (referred to as the leachate) that is dependent upon the type of ore being extracted. In the case of copper, sulfuric acid is used, because it reacts with the copper to create Copper Sulfate, a by product that has many pote

REVIEW OF AGGLOMERATION PRACTICE AND FUNDAMENTALS IN HEAP

ABSTRACT This article reviews agglomeration practices for precious metal and copper heap leaching. Both industries prefer drum to conveyor agglomeration, particularly for clayey ore or ore having a high fines content. Precious metal heap leaching operations opt for cement in a dosage from 2.5 to 10 kg cement/t of ore (520 lb/ton) added to a cyanide solution.
