A new process for the production of defluorinated dicalcium phosphate using phosphate rock was developed. This new process has the main characteristic of being clean, without the production of any liquid waste. The process has essentially three main steps: phosphate rock digestion, defluorination and neutralization.
When phosphate rock is leached with hydrochloric acid, radium can be removed by coprecipitation with and uranium by extraction with a 5% solution of tributyl phosphate in hexane or ...
Full Text: This invention relates to a process for the manufacture of feed grade dicalcium phosphate. Dicalcium phosphate known, as DCP is a commonly used animal feed supplement and it is desirable to obtain dicalcium phosphate free of contaminants, particularly fluoride containing compounds.
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.

phosphate rock and processed into all the products that keep our world running. A key component in crop production, livestock feed, and even in consumer products, in 2014 alone, world phosphate rock production was at a staggering 225 MT and projected to increase in the coming According to the USGS, 95% of the phosphate rock
Dicalcium phosphate shows the most commonly used production method is known as the "wet acid" route in which rock phosphate is reacted with sulphuric acid to produce phosphoric acid. After concentration and purification to reduce the level of undesirable elements, this phosphoric acid is
pure dihydrate dicalcium phosphate. In the final stage, this precipitate is granulated and dried. This Ecophos process has several advantages over classic technology: The classic process uses sulphuric acid to dissolve rock phosphate; but, in addition to the P2O5, most of the other chemical elements present in the rock
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 by direct acidulation of phosphate rock. In general, when phosphate rock is treated with sulfuric acid, monocalcium phosphate or phosphoric acid is formed. If less sulfuric acid is used, dicalcium phosphate should be formed theoretically, however only monocalcium phosphate and undecomposed phos phate rock result in ...
As such, phosphorus is a key ingredient in animal feeds, namely Monocalcium Phosphate (MCP) and Dicalcium Phosphate (DCP). While only about 5% of global phosphate consumption goes toward animal feed production, the production of phosphate animal feeds plays a critical role in maintaining livestock health and overall food security. And with ...
