The c omposition of igneous rock is the result of the crystallization of cooling magma. The distribution of P 2O5 and other minerals is often random Therefore, igneous phosphate beneficiation is usually similar to the processing of

A Tailor Made Approach for the Beneficiation of

The beneficiation of phosphate rock can often be simplified and made more economic by taking into account the distribution of P2O5 and impurities as a function of their deportment between the size fractions resulting from mined and comminuted sedimentary phosphates. A number of case studies developed by TBT are presented in the current paper.

It is one of the most soft and receptive phosphate in West Africa (Truong et al., 1978).It is used as pulverized form with 30% P 2 O 5.TRP, actually commercialized, presents 0.007% of solubility in water.

Optimization of Aspergillus niger rock phosphate

2015-6-25  A biotechnological strategy for the production of an alternative P fertilizer is described in this work. The fertilizer was produced through rock phosphate (RP) solubilization by Aspergillus niger in a solid‐state fermentation (SSF) with sugarcane bagasse as substrate. SSF conditions were optimized by the surface response methodology after an initial screening of factors with significant effect on RP
