The Solution Interaction of Tetrathionate Ions and Sodium Isobutyl Xanthate and Its Effect on the Flotation of Galena and Chalcopyrite

Tetrathionates have been found in significantly high concentrations recycled process waters from massive sulphide ore processing plants. These polythionates react with xanthate added to flotation pulps thus reducing dosages solution potentially affecting performance. The current study focused on the effect of tetrathionate-xanthate reaction mineral recoveries. Ore dissolution studies confirmed generation tetrathionates by copper-lead-zinc ores. In 20 min, consumed more than half at pH 7. Rest potential measurements and Fourier transform infrared spectroscopy (FTIR) showed that degree collector-mineral interactions both galena chalcopyrite was greatly reduced presence a 2000 mg/L tetrathionate solution. Microflotation tests recovery less sensitive as indicated small changes Galena action surface declined when floated collector 500 fundamental results lay sound base which discussion into significance performance ores can be developed.
