Sulfhydryl Phosphorus-Containing Collectors in Flotation of Copper-Nickel Platinum-Group Metals

摘要

The analysis involves influence of sulfhydryl phosphorus-containing collectors (SPC) on flotation of copper-nickel ore-bearing metals from platinum group. Efficiency of SPC and butyl xanthate combination is illustrated, and their optimal ratio is determined. The authors study influence of the test agents on electrode potential and hydrophobic behavior of pyrrhotine, pentlandite and platinum black. UV and IR spectrophotometry has shown origination of disulfide di-isobutyl dithiophosphinate on the surface of pyrrhotine.
