Cyanide and removal options from effluents in gold

2013-9-1  Although the use of cyanide is mostly perceived by the general public as being associated with the mining and metallurgical processes, only about 13% of world cyanide production is consumed by these industries with the remaining percentage being used elsewhere (WHO ECEH, 2000, Mudder and Botz, 2001, Mudder et al., 2001a, Mudder et al., 2001b,

A Review of the Cyanidation Treatment of Copper-Gold

2020-5-21  Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has been adjusting its methods

Preg-robbing gold ores ScienceDirect

Preg-robbing is an important phenomenon that inhibits gold recovery due to the presence of naturally occurring carbonaceous matter. In case of certain ores, gold recovery by cyanidation is limited by the presence of naturally occurring carbonaceous material that adsorbs gold from alkaline cyanide solution unless steps are taken to prevent this adsorption reaction from
