Precious Metals Gold and Silver Mineral Industry Solution

Carbon in Leach Circuit Carbon-in-Leach Circuit (CIL) For over a hundred years, miners have used dilute alkaline cyanide solutions (e.g., sodium cyanide [NaCN] around pH 10-11) to leach (dissolve) gold and other precious metals, from their ores. The gold is usually in the form of small flakes mixed with other minerals.

plant and/or full-scale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine.

Leaching | geochemistry of soil - Encyclopedia Britannica

Leaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer. This transport results in a porous and open top layer and a dense,
