Gold Cyanidation Process - 911 Metallurgist

2016-6-8  The gold cyanidation process is the most important method ever developed for extracting gold from its ores. The reasons the widespread acceptance of cyanidation are economic as well as metallurgical. It usually obtains a higher recovery of gold than plate amalgamation and is easier to operate than the chlorine or bromine process.

What is Gold Cyanidation? (with picture)

Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be

2002-9-1  For 18 years, the process has been successfully applied at scores of gold mines worldwide. This process is based upon conversion of CN WAD to cyanate using a mixture of sulphur dioxide and air with copper sulphate (CuSO 4) catalyst. Due to the need to treated the tailings slurry, the Inco process was selected the cyanide destruction process in 1994.
