  • Assessment of water quality effects on flotation of copper

     · The presence of thiosulphate ions in the water used for oxidized ore flotation has shown significant influence on copper and cobalt recovery. At high thiosulphate concentrations a decrease in the concentrate mass pull could be assumed. Reusing process water has thus induced decrease in copper and cobalt recovery.
