Flotation of gold and gold-bearing ores
Early work on gold particles with copper sulfate showed no improvement in recovery but an increased rate of flotation of gold (Leaver and Woolf, 1934). More recent laboratory testwork on a refractory gold ore has shown, however, that a 5% increase in free gold flotation recovery is achievable when adding copper sulfate (Teague et al., 1999b).
