Influences of soda-water glass binder and pelletisation conditions on the quality of fluorite pellets.

The agglomeration process is used to obtain coarser fluorite concentrate after flotation, for use as flux in ferrous metallurgy. The effect of sodium silicate (waterglass) as a binding agent and of process conditions on the quality of fluorite pellets, particularly their impact and stress resistance, was investigated using fluorite concentrate from the Ravnaja deposit, Krupanj, Yugoslavia. It was found that changes in quantity of binder, homogenisation time and amount of added water significantly affected pellet quality. The pellets with 4.0% and 6.0% Na2SiO3 had good pellet quality in terms of chemical composition and impact resistance.
