Mineral Processing Equipment : Flotation of gold silver and copper fiji - A type of mining equipment that can trigger the development and change of the beneficiation technology industry. The main core machines are ball mills, rod mills, flotation machines, magnetic separators, etc.
Can influence the behaviour of gold in flotation, leaching and/or recovery processes. electrum with a high silver content may give poor gold extraction due to tarnishing of the silver (fleming, 1998). the presence of copper in the ore at above 0.3% concentration may make direct cyanidation uneconomic without re-treating the cu(cn)2.
