For the new production unit, research was conducted on obtaining dicalcium phosphate with the use of hydrated lime and burned lime, extractive phosphoric acid with …
The wet process results in a relatively low-grade purity of phosphoric acid, however the economic benefits allow the wet process method feasible for the fertilizer industry; additionally, the ease ...
The most important parameter of the usability of feed phosphate is the phosphorus availability in feed. For phosphorus assimilation, the compound type in which it is present and the degree of its hydration are very important (Okoñski, Losek, & Rucka, 1978).For example, monocalcium and monosodium phosphates and phosphoric acid have the highest assimilation …

Di -calcium phosphate exists in two forms: the anhydrous form (CaHPO. 4, monetite) and the dihydrate form (CaHPO. 4, 2H. 2. O, brushite). Brushite, also commonly encountered in the literature under the abbreviation DCPD (for dicalcium pho- s-phate dihydrate) and more rarely as CHPD (for calcium hy-drogen phosphate dihydrate) is an acid calcium ...
The wet process consists of reaction, filtration and concentration steps. The phosphate rock is ground and acidified with sulfuric acid in the reactor vessel. In the reaction, the tricalcium phosphate in the phosphate rock is converted to phosphoric acid and to the insoluble salt calcium sulfate (CaSO 4), also known as gypsum.
The typical dicalcium phosphate manufacturing process includes first a degreasing step of fine crushed bones in hot water (80° to 85°C). Regularly shaking removes a high percentage of proteins. The dried bone chips then undergo a demineralisation process: they are submitted over a total period of 4-5 days, to a sequence of solutions
