Optimization of thermal beneficiation of a low grade ...

01/04/1995  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 energy. LZ. Zafar et al. /Int. J. Miner. Process. 43

The potential of Hazara phosphates for phosphoric acid ...

The largest ore body (Lagarban area) of Hazara Administrative Division located 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 deposits are not beneficiable by dry and wet screening due to significant phosphate losses which take place. Phosphate

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. In this work, the effect

Abstract: The enrichment of the low-grade-phosphate ore of the Tozeur-Nefta deposit was investigated using scrubbing-attrition, ball grinding and anionic/cationic 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

A review of the beneficiation of calcareous phosphate ores ...

01/06/2010  The beneficiation of phosphate ores containing carbonate gangue by conventional techniques such as physical separation methods or flotation is very difficult due to the similarities in physico-chemical properties of constituent minerals present in the system. Carbonate-rich phosphate deposits can be processed by calcination and by selective acid leaching methods. However,

SELECTIVE LEACHING OF LOW GRADE CALCAREOUS PHOSPHATE

The beneficiation of phosphate ores containing carbonaceous gangue is complicated because of the similarities in the chemical behavior of the minerals present [Robinson 1978, Mew 1980, Baudet 1988]. Calcite may consume part of the sulphuric acid used for superphosphate manufacture, but dolomite is more objectionable since magnesium in quantity renders the phosphoric acid unacceptably viscous ...
