Recovery of Gold from Solutions
Cyanidation has been used to extract gold (and silver) from ores, concentrates, and calcines since the 1890s. The precipitation of gold from cyanide solutions by zinc cementation was patented in 1884 and was applied industrially as early as the cyanidation process.

The Carbon-in-Pulp (CIP) gold processing technology has enabled a rapid, world-wide growth in gold production. As a result, gold is one of the few winners for the mining industry in the 1980's. The key step in the CIP technology is the adsorption of the gold(1) dicyanide ion, Au(CN)2-, onto coarse carbon granules.

What Is CIP and CIL?
CIP and CIL method is a new process for processing precious metal-containing pulp on the basis of the conventional cyanide gold extraction method. In CIP process, leaching and adsorption are two operations, the leaching tank is used for cyanide leaching of the slurry, and the carbon slurry tank is used for adsorption of gold by activated carbon.

Application Note Cyanide Leach Process
Cyanide Leach Process - pH Mining: Gold Processing While there are many different processes to remove gold from its encapsulating ore, cyanide leaching (cyanidation) is perhaps the most common and well known. A cyanide solution (NaCN or KCN) is elevated to a high pH level (>10.5pH) so that free cyanide (CN-) will dissolve the gold in the ore.
