PRODUCTION OF PHOSPHORIC ACID

phosphate ores have differing compositions within the same source Most phosphate ores have to be concentrated or beneficiated before they can be used or sold on the international phosphate market Different techniques may be used at the bene-ficiation stage, to treat the same ore for removal of the gangue and associated impuriti...

Phosphorite

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate mineralsThe phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5)Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5This occurs through washing, ,...

Journal of Analytical Methods in Chemistry

The theory of using dilute organic acid solutions to leach the carbonaceous part from low-grade carbonaceous phosphate ore has been proposed by researchers as an effective approach to increase the proportion of P and to utilize the abundant low-grade resource In this paper, a comprehensive experimental study was carried out to confirm the feasibility of organic acid leaching and investigate ....

Phosphate Flotation

For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 30-32% P2O5 content The growing fertilizer industry has increased the demand for phosphate rock from which super-phosphates are produced The fertilizer market is very competitive...
