Flotation Of Sulfide Mineral Species With Oils

Flotation mechanisms of molybdenite fines by

· The flotation mechanisms of molybdenite fines by neutral oils were investigated through microflotation test turbidity measurements infrared spectroscopy and interfacial interaction results of the flotation test show that at pH 2 11 the floatability of molybdenite fines in the presence of transformer oil is markedly better than that in the presence of kerosene and diesel oil

Eucalyptus oils as green collectors in gold

· Eucalyptus oils were recorded in early literature as both collectors and frothers in the flotation of copper lead and nickel sulfide ores (Lyster 1914 Shellshear 1916 Taylor and Bull 1929 Bull and Ellefson 1934 Nevett 1936 Taggart 1945 Wark and Sutherland 1955 Gaudin 1957) However literature only notes one commercial operation that successfully recovered gold with

The oxidation of copper sulfide minerals during

· Upon oxidation the sulfide mineral surface becomes increasingly covered with metal oxidation products and the zeta potential versus pH curves of these sulfide minerals become less negative and even positive The iso electric point of the oxidized sulfide minerals is therefore increased and lies between that of elemental sulfur and that of the corresponding metal hydroxide species
