A Study On The Effect Of Active Pyrite On Flotation Of

Flotation is one of the most widely used techniques to separate valuable minerals from gangue minerals in the mineral processing because of its ability to treat low grade and complex raw materials in the fine particle size ranges [3 4 5 6 7] Froth flotation takes place in the presence of three different phases including solid (particles) liquid (water) and gas (air bubbles).Ore microscopy tests were done on the concentrates with 55 and 75 of grain size 74 μm at pH 10 and 12 All particles of copper minerals were divided by grain size fractions and by the degree of liberation Analysis have shown that degree of liberation was higher in finer grinding products.
