Therefore, spreading phosphate rock on fields had little effect on plant growth. However, in the mid1800s, chemists discovered that mixing sulfuric acid with phosphate rock would make a soluble fine powder called superphosphate; this discovery turned phosphate rock into the valuable fertilizer it is today. A caveat, however, is that once
A new process to produce defluorinated dicalcium phosphate (DCP) using phosphate rock concentrate has been developed. This new process has as main characteristic the low concentration of P2O5 in the liquid phase. The process comprises three main steps: solubilization of the phosphate rock concentrate with sulfuric acid, defluorination of the phosphoric acid solution with potassium sulfate and ...

How are Phosphate Feed Additives Made? The most popular form of feed grade phosphate is dicalcium phosphate (DCP), but its production is not the industry journal All About Feed, explains, "The rock phosphate is first digested with sulphuric acid, yielding phosphoric further filtration, purification and defluorination steps, this ''feed grade'' phosphoric acid is ...
Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMPA" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCPM"), Ca(H 2 PO 4) 2 ·H 2 O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening agents.
Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make .
No matter what product phosphate rock is destined for, it must first be mined and beneficiated. Mined phosphate rock beneficiation differs greatly from one deposit to the next, with any combination of crushing, screening, flotation, filtration, classification, and more carrying out the job. The ore resulting from the beneficiation process

Process For Making Dicalcium Phosphate From Rock Phosphate
Dec 01, 2003· At Tessenderlo''s phosphate plant in Ham, in northern Belgium, phosphate rock is turned into a very pure dihydrated crystalline dicalcium phosphate. This isn''t the only method the group uses to make feed phosphates. Intimate knowledge of all available phosphates, claim the company''s experts, is the secret to good phosphorus nutrition for all species of livestock.

Dicalcium phosphate crystals are precipitated and after filtration and drying the resulting product is a very pure crystalline dihydrate dicalcium phosphate that is sold as Aliphos® Dical. Dicalcium phosphate is obtained from degreased bones which are demineralised by hydrochloric acid treatment and precipitated by a saturated lime solution.
Abstract. This paper presents results laboratory experiments to test a new process for manufacture of dicalcium phosphate. The process is based on the nitric acidulation of phosphate rock concentrate, followed by neutralization of the extract liquor with calcium carbonate.
