摘要

Polysaccharides have been used as depressants for naturally hydrophobic talc in the flotation of base metal sulfide ores, precious metal sulfide ores and platinum group metal (PGM) sulfide ores. The results of this surface chemistry study confirm guar gum as a preferred polysaccharide for talc depression in the flotation of these ores. In addition to the practical application of the research results, the surface chemistry results are of academic significance, providing further information to understand how polysaccharide depressants function in these complex sulfide flotation systems.
