· Phosphate rock (or Phosphorite) basically refers to any form of rock that possesses a high phosphorous content. Often extracted by means of surface drilling, this rock is mined through a blasting and harvesting process. Its uses …

· 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.

· Abstract. Phosphoric acid (H 3 PO 4, PA) is an industrial acid, produced from two main types of phosphate rock: sedimentary and igneous.In the classical wet process, wet process PA is produced by a reaction between the ore and sulphuric acid, forming 30% solids thick slurry, in three stages: acidulation, filtration and concentration to produce a 50%P 2 O 5 acid.
