biooxidation of gold ores in senegal

In the biooxidation process bacteria partially oxidize the sulfide coating covering the gold microparticles in ores and concentrates In this way gold recovery from refractory minerals can increase from 1530 to 8595 In the last 15 years at least ten largescale commercial gold processing units have been established in South Africa Brazil Australia Ghana Peru and USA
