rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.

teiperature, grinding time, drying tenperature, final moisture content, acidulation ratio and acid concentration. The Process Reactions It has been r^orted (27, 28) that the main constituent of phosphate rock is fluorapatite. The principle products of the action of sulfuric acid on fluoirapatite are monocalcium phosphate and calcium sulfate. The
Phosphate Rock Beneficiatin Plant. The processing of phosphate rock from impurities and nonphosphate materials for use in fertilizer production consists of beneficiation, drying or calcining at some operations, crushing, grinding and classification etc. Phosphate rock from the mines is first sent to beneficiation units to separate sand and clay and to remove impurities.
Reactive Phosphate Rock (RPR) is a naturally occurring phosphate-bearing mineral used in the production of superphosphate and also as a fertiliser providing a plant phosphate 5 source. Bentonite is an absorbent aluminium phvllosilicate clav which consists of montmorillonite (Na,Ca)o.33(Al,Mg)2Si40io(OH)2-(H20)n.
Beneficiation of Rock Phosphate Fertilizer industry requires a high grade rock phosphate in order to produce fertilizers of desired quality. For instance, superphosphate industry would not use a rock phosphate containing less than 30% P 2 O 5 (13.1% P). Generally, rock phosphate with +31% P 2 O 5, Fe 2 O 3 and Al 2 O 3 below
The ultrafine activated rock phosphate (UARP) was prepared and its phosphorus availability and fertilizer efficiency as affected by amendment of activator and grinding was studied using chemical analysis, infrared spectrum (IR) analysis and pot experiment.

Rock phosphate (RP) is a natural source of phosphorus for agriculture, with the advantage of lower cost and less impact on the environment when compared to synthetic fertilizers. However, the release of phosphorus (P) from RP occurs slowly, which may limit its short-term availability to crops. Hence …
Thus the availability of basic raw material, i.e. Rock Phosphate has made this unit as the most strategic unit of the company. The entire unit is fully integrated with in house facilities such as rock grinding, finished goods storage including gruanules as also stand-by DG power sets. The Company's installed capacity is 1,81,000 MT of SSP.
Enriched Rock Phosphate. Rock phosphate, also known as phosphorite, is a sedimentary rock with a high phosphorus content by weight. At 17 to 30% phosphorus by weight, enriched rock phosphate is one of the best sources of phosphate for growing crops. Rock phosphate is often found in limestone and other sedimentary rocks.

To further improve efficacy, ultra-fine grinding of phosphate rock to 10–20 μm and combining with lignin which activates the phosphate rock has been found to enhance P uptake to levels comparable to, if not better than, water-soluble P fertilizers in pot experiments (Huang et al. 2014).

Bone meal contains tri calcium carbonate or hydrated tri-calcium phosphate. This also contain sodium, magnesium and carbonate. Bone meal is prepared by crushing bones and availability of phosphorus in bone meal increases as material is crushed to a finer size. Raw bone meal It is prepared by grinding the bones as such without any treatment.
The processing of phosphate rock from impurities and nonphosphate materials for use in fertilizer production consists of beneficiation, drying or calcining at some operations, crushing, grinding and classification etc. Phosphate rock from the mines is first sent to beneficiation units to separate sand and clay and to remove impurities.
Soft rock phosphate, also called CalPhos or colloidal phosphate, is a great source of potassium and calcium for your plants. Our CalPhos comes from phosphate rock mined in Florida, which was formed millions of years ago from the mineralized remains of marine creatures.

Consequently, P availability depends mostly on soil pH, reaching its maximum at pH close to 6.5; at lower pH, P precipitates as Fe- or Al-phosphate or is adsorbed by active surfaces (Parfitt, 1989), while at higher pH, it precipitates as Ca-phosphate.
Defluorinated and Fused Phosphate Rock. Defluorinated phosphates are obtained by calcining or fusing phosphate rock with silica and/or phosphoric acid in the presence of water vapor. At temperatures ranging from 1,400° to 1,600° C., the bulk of the fluorine is evolved, and the P2O5 is rendered citrate soluble.
