Adsorption of copper sulphate on PGM-bearing ores and its

Jun 01, 2016 The flotation survey results shown in Fig. 9 shows that the froth structure is altered by the addition of copper sulphate and that the entrainability decreased when copper sulphate was added to the system. This means that there was less hydrophilic gangue collected per unit water in the presence of copper sulphate than in the absence of copper

The Application of Xanthate in Froth Flotation Process

Apr 11, 2019 Xanthate Application in Copper Froth Flotation. In the flotation process of copper ore, xanthate mainly reacts with Cu2+. Therefore, when processing minerals containing more Cu2+ on the surface, the effect of xanthate is stronger, and the order of its action is: Cu2S > CuS > Cu5FeS4 > CuFeS2. 4.
