The process design of gold leaching and carbon-in-pulp

African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80% passing 75µm) to ensure that all non-refractory gold is readily accessible for cyanide leaching. There are several variations ofProduction of Gold,other processing techniques are used to produce 99.9% pure gold bullion from the ore. The results of the feasibility study show that the ore can be processed by agitation leaching, which is preferred over heap leaching due to the low recovery associated with the heap leaching technology. The problem is to find the break-even price of gold for
