Isolation, identifiion and characterization of ...and rock phosphate (RP) as a phosphate source was estimated at Dr. Raman University, Kota, Bilaspur (Chhattisgarh). The result revealed dominance of Pseudomonas syringae as major phosphate solubilizers, along with Bacillus subtillis followed by Pantoea dispersa, Bacillus circulans. Use of these PSB as bioinoculants increased the available P in soil to the extent of 194 and 246 µg/ml of P ...

Phosphate Rock ProcessingPhosphate rock from the mines is first sent to beneficiation units to separate sand and clay and to remove impurities. Steps used in beneficiation depend on the type of rock. A typical beneficiation unit for separating phosphate rock mined in Florida begins with wet screening to separate pebble rock that is larger than millimeters (mm) ( inch [in.]) or 14 mesh, and smaller than ...
Optimization of Aspergillus niger rock phosphate ...The fertilizer was produced through rock phosphate (RP) solubilization by Aspergillus niger in a solidstate 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 solubilization. The optimized levels of the factors were 865 mg of biochar, 250 mg of RP, 270 mg ...

Solubility and Efficiency of Rock Phosphate Fertilizers ...Phosphate fertilizers are produced from rock phosphate (RP), a natural nonrenewable resource. About 80% of the RP mined annually is used for fertilizer production and, considering the current level of consumption, it is expected that reserves will vanish in three centuries time [2,4].The possibility of exhaustion of this resource may compromise global food production [].
A Tailor Made Approach for the Beneficiation of Phosphate RockPhosphate rocks from different deposits possess a wide range of properties related primarily to the geological origin of the phosphate. In parallel, beneficiation methods for phosphate rock are finite and include: comminution and size separation (crushing, grinding, attrition, screening and classifiion), mineral separation (flotation, gravity and magnetic separation) and ocassionally ...
