About this document
Gold Recovery: Electrowinning vs. Zinc Precipitation by Maame Ama Frempong is a document available to read on EtoBox.
The document discusses methods of gold extraction from ore. Cyanidation involves dissolving gold ore in a weak cyanide solution. Zinc precipitation and electrowinning are two main processes for recovering gold from the cyanide solution. Zinc precipitation involves adding zinc dust which reacts with cyanide to precipitate gold particles. Electrowinning involves electrolysis to reduce gold ions onto a cathode. Both methods produce purified gold, but electro winning is more efficient and produces higher purity
