The phosphate rock, imported from Nauru, Jordan, Morocco, Israel and the USA, is mainly fluorapatite, Ca5 (PO4)3F and is equivalent to 70 85% Ca3 (PO4)2 by weight. The actual composition of the phosphate rock varies with the source. The sulfuric acid is produced on the site as described in the previous section.
PHOSPHATE ROCK. CAS NO. EINECS NO. MOL WT. 'Rock Phosphate' is a sedimentary rock composed of phosphate minerals high enough, especially apatite. It is used directly in fertilizer and as a source of phosphorous compounds. Apatite includes 10 mineral species and has the general formula X 5 Y (PO 4) 3, where X is usually Ca 2+ or Pb 3+ and Y is F ...

By 1968 Jordan's production of rock phosphate rose to million tons, which was five times more than the production in 1956. The production further increased to million tons by 1976, and by 1985 the total output rose to million tons. This was achieved despite the near closure of Rusaifa mine. The production further increased to million tons in 1986 and million tons in ...

Phosphorite, phosphate rock or rock phosphate is a nondetrital sedimentary rock that contains high amounts of phosphate phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.
· However, rock phosphate is not without its challenges. Though it is a natural source, it is classified as a nonrenewable resource. Continuous use will lead to depletion if no alternative is found. It is predicted that reserves will be depleted in about 500600 years from now (4). Research has shown rock phosphate to be more beneficial in acidic soils than alkaline soils; this is because rock ...
Rock phosphate 30 – 40 do NA phosphate The phosphate mineral in soil is found to occur as tricalcium phosphate Ca 3 (PO 4) 2 in combination with either CaCO 3, Ca F 2, Ca(OH) 2 or CaCl 2. The primary mineral is called 'apatite' and its massive form is sometimes called as 'Phosphorite'. The apatite is of igneous origin found as a constituent of granites, gneisses and basalt ...
Phosphorus in rock is pretty insoluble and thus not directly available to plants. In nature, 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 ...
