Flotation of Gold and Gold-Bearing Ores
A survey of plant operations (O'Connor and Dunne, 1991) revealed that many flotation operators observe that copper sulfate addition appears to influence mainly the froth stability and that there is an optimum dosage – too little resulting in high slime recoveries and too much resulting in froth instability (O'Connor et al., 1990).
