Cyanide free gold recovery CSIRO
Cyanide free gold recovery CSIRO

Aug 21, 2020· The infrastructure for a processing plant that uses cyanidation typically costs $30 million, and is therefore, a barrier to entry for gold miners with smaller deposits that do not fit into the large-scale economies of gold production. Gold recovery by cyanidation is also of environmental and safety concern as it relies on the use of toxic cyanide.
