Apr 30, 2019· The general formula for pure rock phosphate is Ca10 (PO4)6 (X)2, where X is F−, OH− or Cl−. These minerals are called apatites. The most common rock phosphate mined is fluorapatite, which contains impurities like CO3, Na and Mg. Carbonate-fluorapatite (francolite) is primary apatite mineral in the majority of phosphate rocks.

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
Phosphate rock grade is often listed in trade publications as BPL, referring to "bone phosphate of lime," the common name for tricalcium phosphate. Early workers believed tricalcium phosphate was the chief constituent of phosphate rock.

Phosphate rock is a finite, non-renewable resource • Maximum recovery, utilization and recycling of phosphate rock, fertilizers, byproducts and wastes should be emphasized Reserves and resources • Reserves are a dynamic quantity • Resources can become reserves • There is no evidence for a “peak phosphorus” event
The residual value of Christmas Island C-grade ore, 500 degrees C heated (calcined) C-grade ore (Calciphos), and superphosphate was measured in three experiments. Plant yield, and bicarbonate-soluble phosphorus extracted from the top 10 cm of soil were used to indicate the effectiveness of the four fertilizers. Using either of these indicators, superphosphate was the most effective fertilizer.
Phosphate rock (PR) is the raw material used in the manufacture of most commercial phosphate fertilizers on the market. With access to large, high-quality reserves of phosphate rock, Morocco, China and US are the most important players in phosphate industry.
Apr 06, 2020· What is Rock Phosphate, Exactly? Rock phosphate also referred to as phosphate rock or phosphorite, is a type of non-detrital sedimentary rock packed with phosphate mineralization, including apatite. In addition to being an essential organic source of phosphorus, phosphate rock also contains limestone, clay, and some other essential trace minerals.

It should be applied to soils prior to planting and can be mixed with compost or manures for additional soil building benefits. This premium powder grade is an excellent nutrient resource
Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.
