3. Grinding: The raw material is ground to the required fineness in a mill and simultaneously dried if required. 4. Sulfuric acid: Elemental sulfur is molten and burned. The sulfur dioxide produced is catalytically converted to sulfur trioxide and absorbed in water, forming sulfuric acid. 5. Phosphoric acid: Phosphate rock is fed into the reactor

The NAC P 2 O 5 solubilities of these PRs and a third rock increased from about 60 to 120 percent with grinding to minus 200 mesh. However, previous experimental reviews (Rogers et al ., 1953; Cooke, 1956; Khasawneh and Doll, 1978) concluded that any increase in PR solubility rarely justified grinding to a size less than 100 mesh for agronomic use.

rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.

Phosphate fertilizers are prepared by beneficiation of phosphate rock to remove its impurities, followed by drying and grinding. The PO 4 in the rock may then be reacted with sulfuric acid to produce normal superphosphate fertilizer. Over 100 plants operating in the United States produce approximately a billion kilograms of phosphate fertilizer ...

Most phosphate processors choose airswept milling systems due to their ability to remove fine particles from the grinding zone. Due to the cushioning effect from newly introduced feed, this allows the grinding action to be concentrated on the large oversize particles. This results in higher yields and, by minimizing overgrinding, lowers energy consumption.

Its available P2O5 content ranges from 18 to 22 percent, depending on the grade of rock and the free -moisture content of the final product. The process consists of mixing finely ground phosphate rock containing 32 percent or more P2O5 with sulfuric acid (55° B.) in the ratio of 100 parts of rock to 85 parts of acid.
