Phosphate rock. Turquoise in graphitic slate from Black Range near Cheshunt, Victoria (Scale: 8 cm) Phosphate rock is a general term used to describe natural mineral assemblages of variable composition that have a high concentration of phosphate minerals. Most of the minerals in phosphate rock belong to the apatite group.

Phosphoric acid (SIC 28741), made from phosphate rock and sulfuric acid, is the primary material input in almost all of the phosphatic fertilizer used in agriculture. Producers of phosphoric acid use two distinct manufacturing processes to produce two very different basic grades of product acid.
The phosphorus from phosphate rock is processed in two main pathways: in order to make phosphate-containing fertilizers for global agricultural, most of the phosphate (~95%) is processed by the "wet process," where phosphate is treated with sulfuric acid to produce phosphoric acid.

Industry Description. Phosphoric acid is a chemical product derived from phosphate rock and is integral to the production of phosphate fertilizers. Four states mine phosphate rock (Florida, North Carolina, Idaho, and Utah) and facilities that produce phosphoric acid are generally located near phosphate rock mines.
1. Introduction. Phosphoric acid is considered as the second mineral acid produced after the sulfuric acid. The major part of phosphoric acid production (90%) is dedicated to chemical fertilizers (Belboom et al., 2015), the rest being used as raw materials for the production of detergents, animals food, additives in toothpastes, ingredients of …
Phosphoric acid is commonly produced industrially by two main methods: the 'wet process' and the 'thermal process'. The Wet Process: This is the most common method of production. In this process, phosphate rock (Ca 3 (PO 4 ) 2 ) is reacted with sulfuric acid (H 2 SO 4 ) to produce phosphoric acid and calcium sulfate.

In the wet process, phosphoric acid is produced by reacting sulfuric acid (H 2 SO 4) with naturally occurring phosphate rock.The phosphate rock is dried, crushed, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (gypsum, CaSO 4), which …
phosphate rock mined in the United States was used to manufacture wet-process phosphoric acid and superphosphoric acid, which were used as intermediate feedstocks in the manufacture of granular and liquid ammonium phosphate fertilizers and animal feed supplements. About 25% of the wet-process phosphoric acid
Rock phosphate or soft rock phosphate fertilizer is a fantastic way to add - you guessed it - more phosphorus to your garden soil. 2.75M ... In most cases, it reacts with sulfuric acid to make phosphoric acid (P2O5) before it can be used. The acid is added to pulverized phosphate rock. This acid is then processed further to create good ...
Phosphate Rock and Phosphoric Acid ; View Profile . Neil Griffiths. Neil is responsible for researching and writing the current information report on phosphates, a global market and price review of the week. His main area of focus since joining the industry in 2000 has been phosphates and he has experience producing short term forecast reports ...
The agronomic effectiveness of unground North Carolina phosphate rock (PR) and partially acidulated phosphate rocks (PAPR) prepared by acidulation of the PR with 30%, 40% and 50% of the phosphoric acid needed for complete acidulation, was determined in a 4 year field experiment on permanent pastures.
Phosphate rock extraction from its ore, and its subsequent conversion into fertilizer materials and industrial chemicals, is a relatively mature art. While production of phosphoric acid from sedimentary phosphate rock via the “wet process” dominates the...
Phosphate Rock. The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is …

Treating phosphate rock with sulfuric acid produces phosphoric acid, the water-soluble material from which most phosphate fertilizers are derived. Worldwide, more than 85 percent of the phosphate rock mined is used to manufacture phosphate fertilizers. The remaining 15 percent is used to make elemental phosphorus and animal feed …
The concentrations of 238U, 226Ra, 232Th and 40K maintained in phosphate rock (PR), phosphoric acid (PA) and phosphogypsum (PG) samples and its possible radiation hazards, have been measured.
Pure phosphoric acid is a crystalline solid (melting point 42.35° C, or 108.2° F); in less concentrated form it is a colourless syrupy liquid. The crude acid is prepared from phosphate rock, while acid of higher purity is made from white phosphorus.
The most economical method for making phosphoric acid is by treating phosphate rock with sulfuric acid (H 2 SO 4). Phosphate rock is naturally-occurring rock with large amounts of calcium phosphate (Ca 3 (PO 4) 2). The product of this reaction is generally not very pure, but sufficiently pure for use in the production of fertilizers.
Samples of phosphogypsum (PG) provided by the Spanish fertilizer industry Fertiberia, S. A., sugar (SF) from the Spanish sugar producer Azucarera Ebro, S. L., and phosphoric rock (PR), a commercially available fertilizer, were dried at 45 °C (phosphogypsum) or 105 °C (sugar and phosphoric rock) and digested by acid …
By producing phosphoric rock at scale, South Africa joins major economies including China, USA, Russia, Egypt, Australia, and Saudi Arabia as those with top phosphate reserves. In Africa, Morocco, Western Sahara, Senegal, and Algeria are also recognised phosphate countries, but South Africa has a long-standing and proven route …
When phosphate rock is treated with sulphuric acid in sub stoichiometric quantity, normal superphosphate is formed. If more sulphuric acid is added, a mixture of phosphoric acid and gypsum (calcium sulphate) is obtained. After the gypsum is filtered out, the resultant phosphoric acid can be treated to recover uranium. The basic reaction is:
Florida and North Carolina accounted for 94 percent of the domestic phosphate rock mined and. 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.
