Amalgamation Process of Gold Mineral Processing Metallurgy

Amalgamation Process of Gold. Precipitation of gold and silver on zinc dust or on zinc shavings is fully treated, from the clarification and de-aeration of cyanide solutions to the cleanup and melting of the bullion. The use of aluminum dust, sodium sulphide, and charcoal as precipitants receives attention.
