hazara phosphate beneficiation

Optimization of thermal beneficiation of a low grade ...

1995-4-1  In this study, beneficiation of a high dolomitic Hazara (Pakistan) phosphate ore is attempted using no expensive chemicals or energy which may be required in conventional flotation and calcination methods. Beneficiation by calcination is one of the better known processes. It is based on the dissociation of the calcium carbonate by thermal ...

Beneficiation of low grade carbonate-rich phosphate rocks ...

The carbonate-rich phosphate rocks have no direct use and are rejected all over the world. Substantial amounts of low-grade phosphorites are found along with high grade ore in some areas of Hazara (Pakistan). In the technique described dilute acetic acid solution has been used for leaching of the carbonates contained in Hazara low-grade, carbonate-rich phosphate rocks.
