The potential of Hazara phosphates for phosphoric acid

Phosphate flotation recoveries are also low. Heavy intensity magnetic separation removes iron after the removal of dust from classified fraction. Acid leaching is efficient for removing MgO (up to 84%) with low P 2 O 5 losses. However, removal of iron and MgO by these methods is not considered feasible on economic grounds.

Flotation of phosphate ores containing dolomite

Table IV shows the effectiveness of the dolomite flotation to remove dolomote (measured as MgO) from the phosphorite ore. The dolomite content was 2.16% in the sink product from the heavy media separation, and was decreased down to 0.56% MgO in the phosphate concentrate obtained after grinding and dolomite flotation.
