The first stage of pilot scale beneficiation testwork with a circuit based on this Bateman& 39;s report was completed in December. A second stage involving a further 80t of bulk sample is currently being processed to accommodate fine tuning of the indi ed commercial beneficiation circuit and to provide further concentrate for marketing purposes.
The enrichment of the low-grade-phosphate ore of the Tozeur-Nefta deposit was investigated using scrubbing-attrition ball grinding and anionic/ ionic reverse flotation in order to separate phosphate-rich particles from their gangue. The choice of the beneficiation process was based on the petrographic mineralogical and chemical analyses. The petrographic and mineralogical studies have

The phosphate reserves in Pakistan are small. The largest ore body Lagarban area of Hazara Administrative Division lo ed in the North East of the country has 3.25 measured and 6.71 inferred million tons phosphates rock of silicious and dolomitic nature with 25.8% average P2O5 contents besides high impurities of R2O3 3.3% and MgO up to 6% .
The pilot plant has the beneficiation facilities for processing of almost all types of ores using different processing techniques such as froth flotation gravity-based separation low and high intensity magnetic separation and hydrometallurgical. Washability and beneficiation facilities of indigenous coal are also available.
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 .
