Phosphate Rock

Phosphate Rock

Physical Characteristics of Phosphate Rock

Phosphate rock in sedimentary rocks, and a native to metamorphic and igneous rocks, in addition to the individual circumstances, always exist in orthophosphate form the mineral of phosphorus, phosphorus mainly mineral apatite. Phosphorus is an important chemical raw materials, but also of the essential elements for crop growth, phosphorus must pour out a large stream of extracted from phosphate rock used in industry, used in the manufacture of yellow phosphorus, red phosphorus, phosphoric acid, phosphate fertilizer and phosphate.

Classification and Distribution of Phosphate Rock

Phosphate rock content according to the origin of mineralization can be divided into sedimentary rock, metamorphic rock and volcanic rock. At present, the industrial production of Marine sedimentary phosphate rock is about 85%, the rest mainly for igneous rock phosphate rock. Guano demanded phosphate rock debris is droppings, directly or indirectly, the mineralization and reserves is not big, but now accounts for about 2% of the world phosphate rock annual, igneous or metamorphic grade of phosphate rock is generally low, but optional good, by flotation, high grade of concentrate can be obtained. The industrial production of the Soviet union cora phosphate rock, para bo tile phosphate rock in South Africa, Brazil, him to langa phosphate rock, kam screen phosphate rock in China.

Application of Phosphate Rock

The consumption structure of about 80% of phosphate rock in the world after the production of phosphate fertilizer used in agriculture, the rest is used in the extraction of yellow phosphorus, phosphoric acid and other phosphate series products. Phosphorus chemical products in industry, national defense, cutting-edge science and has been widely used in people’s life. Except to used for phosphate fertilizer, phosphorous pesticides in agriculture, poultry and livestock, in detergents, metallurgy, machinery, mineral processing, drilling, plating, paint, paint, textile, printing and dyeing, tanning, medicine, food, water treatment, glass, ceramic, enamel, refractories, building materials, daily chemical industry, papermaking, ammunition, fire retardant and extinguishing etc widely used. With the development of science and technology, high purity and special function of phosphorus chemical products in the advanced science, defense industry, etc, are further popularization and application, emerged a large number of new products, such as: electrical materials, sensors, ion exchanger and catalyst, artificial biological materials, solar battery materials, optical materials, and so on. Due to phosphorus chemical products constantly to permeate more industrial sectors, especially in the application of advanced science and emerging sectors, phosphorus chemical industry become an important industry in national economy. Phosphorus chemical products in people’s food, clothing, shelter, line, playing an increasingly important role.
