Double reverse flotation of a very low grade sedimentary

In this study, reverse flotation was applied to recover phosphate from a very low grade (5.01% of P 2 O 5) sedimentary ore. Sodium silicate, starch, tannic acid, aluminum sulfate, (Na,K)Tartarat, sodium tripolyphosphate, H 3 PO 4, and H 2 SO 4 were used as phosphate mineral depressants in acidic and alkaline conditions.

Reverse flotation can be applied for phosphate ores that have high dolomite content [9,10,11,12]. However, there are still considerable difficulties in separating apatite from dolomite by means of reverse flotation. Furthermore, for fine-grained dissemination and complex minerals composition, apatite is often intergrown with dolomite. On the other hand, as calcium-bearing minerals, apatite and
