89 percent of the marketable phosphate rock produced during 1989. Other states in which phosphate rock is mined and processed include Idaho, Montana, Utah, and Tennessee. Alternative flow diagrams of these operations are shown in Figure 11.21-1. Phosphate rock from the mines is first sent to beneficiation units to separate sand and clay and
The most common raw material \⠀ used in commercial P fertilizer production is PR which contains a calcium phosphate minera\൬ called apatite. Phosphate rock is produced in several countries. There are two main types of PR deposits: sedimentary and igneous.
While most phosphate rock goes to the production of MAP and DAP fertilizers, this life-giving mineral can be made into a variety of fertilizer products and blends through the process of granulation. FEECO has been a leader in the fertilizer industry since 1951. We’ve helped companies around the globe to develop premium phosphatic fertilizer ...

The phosphate ion is a polyatomic ion with the empirical formula PO 3− 4 and a molar mass of 94.97 g/mol. It consists of one central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. The phosphate ion carries a −3 formal charge and is the conjugate base of the hydrogen phosphate ion, HPO 2− 4, which is the conjugate base of H 2 PO −
The concentration of phosphoric acid is normally expressed as % P2O5 (percent phosphoricanhydride) rather than % H3PO4 (percent phosphoric acid). In a wet process facility (see figure 1), phosphoric acid is produced by reacting sulfuric acid (H2SO4) with naturally occurring phosphate rock.
