A method is disclosed for the manufacture of phosphoric acid directly from phosphate rock wherein the crushed phosphate rock is mixed with dilute phosphoric acid to form a slurry and the slurry is then heated to produce calcium monophosphate. Thereafter, oxalic acid is added to the slurry to precipitate the calcium therein as calcium oxalate which is separated.
In 2018, fertilizer consumption for Iran was 47.5 kilograms per hectare. Fertilizer consumption of Iran increased from 5.8 kilograms per hectare in 1969 to 47.5 kilograms per hectare in 2018 growing at an average annual rate of 6.64%. Fertilizer consumption measures the quantity of plant nutrients used per unit of arable land. Fertilizer products cover nitrogenous, potash, and phosphate ...
Jun 08, 2021· Rock phosphate, or phosphorite, is mined from clay deposits that contain phosphorus and is used to make organic phosphate fertilizers that many gardeners utilize. In the past, rock phosphate was used alone as a fertilizer, but due to a lack in supply, as well as low concentration, most applied fertilizer is processed.

The Kingdom of Saudi Arabia's rock phosphate deposits are estimated at 960 million tonnes – the 11th largest reserves in the world. In 2009, the Islamic Development Bank (IsDB), set about developing these natural resources – and in doing so, diversifyed the country's export economy – through the Ma'aden Phosphate Fertilizer Complex project.
Chemical properties. The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −, which in turn is the conjugate base of orthophosphoric acid, H
Feb 10, 2007· Five phosphate-solubilizing bacteria (PSB) used in this study were isolated based on their ability to solubilize tricalcium phosphate (TCP) in Pikovskaya's medium. Among the tested bacterial strains Burkholderia sp. strain CBPB-HIM showed the highest solubilization (363 μg of soluble P ml−1) activity at 48 h of incubation. Further, this strain has been selected to assess its shelf life in ...
Aug 23, 2016· A potent phosphate solubilising fungus was isolated from an Iranian phosphate mine and selected for solubilisation of rock phosphate (RP). The identified fungus was characterised by calmodulin-based polymerase chain reaction method as Aspergillus tubingensis SANRU (Sari Agricultural Sciences and Natural Resources University).
