How phosphate is mined and processed
About 15% of phosphate reserves are found in volcanic (extrusive) igneous rocks. These reserves are found in Russia, Finland, South Africa and Brazil. Most phosphate reserves are from sedimentary rocks. The phosphate forms in the shallow oceans mainly due to bacterial activity, but only when several conditions are met. Their formation is pretty rare!

Igneous deposits represent the major phosphate ore reserves in South Africa, Brazil and Russia. The Kola province in Russia, where phosphorus is recovered, consists of .
Sedimentary Ore Deposits ~ Mining Geology
Sedimentary deposits are formed through the erosion, transportation, and redeposition of minerals that can survive the rigors of transportation. The most common is silica, which forms a number of materials, including silica sand, sand and gravel, and flint. The precursor is igneous quartz (, in granite), and then the sedimentary deposit may undergo metamorphism and recementing to produce ...

obtain the phosphate ore. This process to obtain phosphate ore from raw phosphate is often called beneficiation. Carbonate gangue removal is a prerequisite prior to the digestion of the phosphate rock by an inorganic acid. Otherwise the development of carbon dioxide from the rock gives rise to excessive ing (Van Der Sluis, 1987). In
In what form is phosphate rock mined?
In 2003, nine firms in four states mined phosphate rock ore, compared to 20 firms in 1997. In 2003 mines produced an estimated million metric tons of phosphate rock, with a value of 895 ...
What are igneous rocks?
Igneous rocks (from the Greek word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.
Phosphite ore deposits SlideShare
Nov 19, 2015· Phosphite ore deposits. • While there are more than 200 known phosphate minerals, the main mineral group of phosphates is the group of apatites. • Calciumphosphates of the apatite group are mainly found in primary environments (in sedimentary, metamorphic and igneous rocks) but also in weathering environments.

geological origins, igneous and sedimentary. The phosphate minerals in both types of ore are of the apatite group, of which the most commonly encountered variants are; fluorapatite, Ca 10 (PO 4) 6 (F,OH) 2 and francolite, Ca 10 (PO 4) 6 (CO 3) x (F,OH) 2x), where fluorapatite predominates in igneous phosphate rocks and francolite predominates

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities.

An ore concentration technique applied most often with igneous phosphate ore is flotation. It can be used when silica has to be removed from the ore. However, calcite (CaCO3), a very frequent byproduct from phosphate ore processing, is difficult to separate by flotation (Becker, 1989).
