Selective flotation of silicates and Ca-bearing

2012-10-1  Flotation of pure minerals constituting the gangue of rare metal low grade ores was performed. Mixed collector synergetic effects confirmed for silicates and Ca-minerals flotation. Selective separation of palygorskite from silicates and Ca-minerals is achieved at pH 8. Reagents consumption lowered with addition of non-ionic reagent for biotite–muscovite flotation.
