Separation of silica from pyrite cinder via reverse cationic flotation

Abstract

This paper describes effective reagent combinations for removal of quartz by reverse cationic flotation from pyrite cinders. This work is based on a hypothesis that a further development in reverse cationic flotation of iron ores implies. A more detailed consideration of the nature of the pyrite cinders. The results indicate that the pyrite cinder is man-made porous ore. Starch was used as a depressant, and laurylamine as the cationic collector. Optimum pH is 8.0~8.5 and optimum mean particle size is around 5um. Flotation of pyrite cinders in both bench and pilot scales is effective and producing of concentrates with SiO2 content below 0.8% and Fe contents up to 68% was obtained from pyrite cinders with SiO2 content 3.9%.
