| Abstract: | This paper presents a research on the process flotation of a carbonate-fluorite resource, which shows that fluorite and calcite can be separated effectively with water glass and dilute sulphuric acid as the inhibitor in neutral condition. We can obtain fluorite concentrate containing fluorite 94.44% and 0.79% CaCO3 with the recovery of 89.35% using a roughing and nine cleaning closed-circuit, of which the middlings are fed back orderly. |
