Cu(II) and Ni(II) activation in the flotation of quartz ...

2005-04-04  At high pH values quartz flotation is also reduced, although copper hydroxide is present on the mineral surface as shown in the zeta potential and adsorption results at pH 10 in Fig. 2, Fig. 3, respectively. One would have expected less adsorption of copper hydroxide on the quartz surface at pH 10 because copper hydroxide is negatively charged at pH values larger than its iep of 9.5 and it ...

Copper Flotation - Mineral Processing Metallurgy

2016-05-16  Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copper-bearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter. Lime is nearly always used for maintaining the alkalinity of the circuit and depressing any pyrite present. The ...

Flotation of Copper oxide ore - Fodamon Machinery

All bound copper oxide can not be dissolved in cyanide solution. The percentage of bound copper in copper oxide is called the binding rate. Gangue minerals are mainly siliceous (e.g. quartz) and carbonate (e.g. calcite, dolomite) are easier to flotation. It is more difficult to separate gangue minerals when they contain more iron hydroxide and ...
