A novel process for sorting fine-sized sulphide minerals by biocoagulation H. Z. KUYUMCU, J. PINKA, T. BIELIG Department of Mechanical Process Engineering and Solids Processing... substances, as well as their influence on the selective biocoagulation were studied. Experimental investigations show that the microorganisms and the sulphide particles below 10 ?m coagulate effectively......

of sulphide minerals flotation separation was analyzed. Three charge transfer models of electrochemistry reaction taking place on mineral particle′s surface were proposed for different system of sulphide flotation, which were model of charge transfer by particle itself, model of charge transfer on interface of mineral particle and liquid phase and model of charge transfer by the collision......
