Potentiality of Indian rock phosphate as liming

01/02/2016 It is estimated that about 260 million tonnes (Mt) of rock phosphate (RP) deposits are available in India,most of which are categorized as low-grade because of their low P content and unsuitable for commercial production of P-fertilizer. Application of RP for direct use in acid soils offers a potential utilization of this mineral phosphate as source of P. From economic point of view, these low

Phosphate Rock Hydrochloric Acid

We are thinking of replacing the HCl acid bath that we are currently using on our zinc phosphate line, with the idea being that we would like to avoid using an acid A. Rock phosphate is made to react with concentrated sulphuric acid which produces a mixture of calcium sulphate and calcium-di-hydrogen phosphate . here we are reacting it with the strong acid HCl, which means that the hydrogen

Separation of H3PO4 from HCl-wet-processing

15/10/2020 Using HCl to replace H 2 SO 4, phosphate rock is decomposed according to the following reaction: (2) C a 5 F P O 4 3 + 10 H C l → 3 H 3 P O 4 + 5 C a C l 2 + H F. Hydrochloric acid route not only avoids the generation of phosphogypsum, but also improve the profits of the process. Due to the excellent reactivity of HCl, even low-grade phosphate rock can be used directly. The beneficiation
