Gold extraction process – Kivu Mineral Mining Company
Gold extraction process. The mineralized rock at Kivu Mineral Mining would require multiple steps in processing to extract the gold. Mineralized rock is first crushed, then ground in large mills to create a fine, silt-like powder. The gold-bearing minerals are then separated from other materials using a process called “flotation.”.
