Gold processing - Miller, Wohlwill, Fire Assay, Karat Fineness
Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold

Estimated Water Requirements for Gold Heap-Leach
Briefly stated, gold heap leaching is a hydrometallurgical process designed to treat amenable low-grade gold ores that contain roughly 0.5 gram per metric ton (g/t) gold to 1.5 g/t gold (Marsden and House, 2006; Wong Wai Leong and Mujumdar, 2010).

Gold processing - Mining, Gravity, Amalgamation Cyanidation
Gold can be freed from these ores or concentrates by treating them with various oxidizing processes. The most common method is to roast gold-bearing minerals at temperatures of 450° to 750° C (840° to 1,380° F) to destroy the interfering sulfides. Oxidation can also be accomplished by the use of high-pressure reactors called autoclaves, in ...

Treatment for gold ores with high content of carbonaceous
The pretreatment of the gold ore using the cationic surfactant benzalkonium chloride did not passivate the carbonaceous matter resulting in a negative effect in the subsequentcyanidation, as the gold extraction slightly diminished as the dosage of surfactant in standard cyanidation tests increased.

An investigation of the carbonaceous component of preg
For many years carbonaceous gold ores have been identified as having the ability to adsorb gold (I) cyanide from leach solutions1-14. This phenomenon, known as preg-robbing, is responsible for poor recoveries as the carbonaceous component of the ore competes with activated carbon used during the leaching and adsorption phase of processing.
