  • Effects of Soluble Metals Flotation

    Most of the soluble minerals were present as sulphates. The next step was to determine the effect, on flotation, of the various sulphates. Sodium and potassium sulphates, when added to fresh tests in the proportion indicated in the analysis, yielded a 13 oz. tailing and a 650 oz. concentrate; thus producing a marked increase in the grade of concentrate without detrimental effect on the tailing.
