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.

How is Sodium Cyanide Consumed during Gold

2020-8-21  The cyanidation plants has been using sodium cyanide to dissolve the gold from the ore in order to recover the gold from the leaching solution. The formula is as follows: 2Au+4NaCN+O2+2H2O→2Na [Au (CN)2]+2NaOH+H2O2. 2Au+4NaCN+H2O2→2Na [Au (CN)2]+2NaOH. From the electrochemical reaction, it can be known that dissolving 1 gram of gold
