Flotation of Gold and Gold-Bearing Ores
The demand for sulfuric acid initiated by the booming uranium industry during the late 1960s provided the catalyst for the installation of pyrite flotation plants on numerous gold mines in South Africa (Bushell, 1970, Broekman et al., 1987).After roasting the pyrite flotation concentrate to generate sulfur dioxide for the sulfuric acid plant, the remaining calcine was …
