Rock phosphate enriched compost: An approach to improve low-grade Indian rock phosphate
Bioresource Technology, 2006In this study, rock phosphate enriched composts (RP-compost) were prepared by mixing four low-grade Indian rock phosphates with rice straw with and without Aspergillus awamori. RP-compost had higher total P, citrate soluble P (CSP), organic P (Org.P), acid and alkaline phosphatase activities, and lower water soluble P (WSP) and microbial biomass C (MBC)

Lead can be immobilized in contaminated soils by phosphate rock (PR) amendment, but its efficiency is generally limited by low solubility of PR. Our study aimed to elucidate whether phosphate solubilizing bacteria (PSB) can promote Pb immobilization through PR solubilization. Results showed that P. ananatis HCR2 and B.

Screening for rock phosphate solubilizing Actinomycetes from Moroccan phosphate mines
Applied Soil Ecology, 2008Three Moroccan phosphate mines, an original biotope rich in insoluble rock phosphate (RP), were explored for the presence of RP solubilizing Actinobacteria. Three hundred actinomycete isolates originating from these mines were tested for their ability to grow on a synthetic minimum medium (SMM) containing insoluble RP as unique phosphate source.

Microbiological acid solutions produced byThiobacillus ferrooxidans andThiobacillus thiooxidans on pyritiferous concentrate were used to solubilize phosphate rock with a high grade in P2O5. Five different mixtures of pyritiferous concentrate and phosphate rock, in different proportions, were used in adequate liquid culture media.

Uranium endowments in phosphate rock
Science of The Total Environment, 2014This study seeks to identify and specify the components that make up the prospects of U recovery from phosphate rock. A systems approach is taken. The assessment includes i) reviewing past recovery experience and lessons learned; ii) identifying factors that determine recovery; and iii) establishing a contemporary evaluation of U endowments in ...

A field trial was conducted for 3 years to evaluate phosphate rocks and phosphate rock/sulphur granules as fertilizers for permanent pastures. Two reactive phosphate rocks, North Carolina (USA) and Chatham Rise (New Zealand), and an unreactive Florida (USA) were used.
