How phosphate is mined and processed 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 55 and 72

What is phosphoric acid? Phosphoric acid is a mineral acid This means it is an inorganic type of acid These are derived from one or more inorganic compounds In the case of phosphoric acid they are derived from inorganic phosphate rocks Acid of higher purity can also be made by using white phosphorus Other examples of mineral acids are sulfuric acid hydrochloric acid and nitric acid

What is Monazite? Monazite is a rare phosphate mineral with a chemical composition of (Ce La Nd Th)(PO 4 SiO 4) It usually occurs in small isolated grains as an accessory mineral in igneous and metamorphic rocks such as granite pegmatite schist and gneiss These grains are resistant to weathering and become concentrated in soils and sediments downslope from the host rock
