Abstract The authors investigate a new reagent—modified water-soluble polymer of polyvinyl caprolactam (PVCL)—as a collector in flotation of gold-bearing sulfide ore. Modified PVCL is obtained by solid-phase modification of poly(N-vinyl caprolactam) by thiourea. The electron scan and laser microscopy identified adsorption of PVCL at gold grains applied …

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).

Flotation

Flotation is an extremely size sensitive process and because the RC drilling process imparts a lot of energy into the sample, the resulting fine particle size distribution is likely to be much finer than required. Also, the detergents used in RC drilling will very often react unfavorably in the flotation cell with other reagents.
