China can influence the behaviour of gold in flotation, leaching andor 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 CuCN2 formed
