Amalgamation is a process used in gold extraction mostly in smallscale mining In Tanzania this is a major source of mercury that enters the environment thus causing pollution sometimes with
The use of direct amalgamation following stamps or primary mills and the use of barrel amalgamation for treating jig and corduroy concentrates Precipitation of gold and silver on zinc dust or on zinc shavings is fully treated from the clarification and deaeration of cyanide solutions to the cleanup and melting of the bullion The use of aluminum dust sodium sulphide and charcoal asFurther Details
The use of mercury to recover gold or amalgamation is a common and simple extraction process but it is dangerous and contaminates air soil rivers and lakes which produces more than 95 of Tanzanias gold and has the highest intensity of smallscale mining in the country Rwamagasa is only 37 km south of Lake Victoria but the areaFurther Details
