Jan 01, 2006· Phosphogypsum is the principal by-product produced by the wet processes involved in the manufacture of phosphoric acid. The main component of phosphate rock is FAp, and so fluorides, such as sodium fluoride (NaF), calcium fluoride (CaF 2), and sodium hexafluorosilicate (Na 2 SiF 6), 6 are contained as impurities in phosphogypsum. In Japan ...
Samples of phosphate rock feed, limestone, phosphoric acid, product and scrubber water were also taken during each run. Each stack gas sample on the dicalcium process extended over a two hour period. All.process data and operating procedures were obtained by EPA personnel.
Selecting a phosphoric acid process341 Кб. The co-precipitated dicalcium phosphate dissolves in the acidic water, and very little re-precipitates into the dihydrate crystals.Processes that utilize gypsum from phosphoric acid plants often require the gypsum to have limited concentration of phosphate and fluoride impurities.
Commercial phosphoric acid manufactured using wet process has been purified by minimizing the iron, cadmium, copper and fluoride content. Bentonite clay is found suitable for removal of humic acids and suspended materials from crude phosphoric acid.

A new process for production of purified phosphoric acid and/or fertilizer grade dicalcium phosphate from various grades of phosphatic materials. Grover L. Bridger, Carl B. Drees, and ; Amitava H. Roy
The invention relates to a combined process for the manufacture of feed grade dicalcium phosphate and pure phosphoric acid. The process comprises the reaction of an excess of phosphate rock with aqueous solutions of a mineral acid selected from hydrochloric acid, phosphoric acid and nitric acid, characterized by the fact that the free acidity of the dissolution liquor does not exceed 60% and ...
A method of producing dicalcium phosphate from calcium phosphate includes reacting the calcium phosphate with a mineral acid such as sulphuric acid to ... Dicalcium-Phosphates- Process, Technology, reacted with a calcium source such as quick lime or limestone to produce dicalcium phosphate.
Paul Scott Dicalcium phosphate powder. Dicalcium phosphate (DCP) is a dibasic calcium phosphate formed by a reactive combination of calcium oxide and phosphoric acid. As a dietary supplement, it is commonly used as a source of calcium and phosphorus for both humans and animals. In this role, the compound is either used as an additive in the preparation of cereal and grain products or purchased ...
Dicalcium phosphate is used as a food additive, it is found in some toothpastes as a polishing agent and is a biomaterial. Manufacturing Process. 1. Dibasic calcium phosphate is produced by the neutralization of calcium hydroxide with phosphoric acid, which precipitates the dihydrate as a solid. At 60 °C the anhydrous form is precipitated:
Then the dried product is treated with phosphoric acid to obtain phosphate and again carry out the drying at a temperature of 145-170°C. the method can reduce the fluoride content in the product to 0.15-0.2% (A.S. USSR №1463733, CL 01 In 25/32, 1989).
