8.1.1 Phosphate Rock Mining The primary method of mining and exploration of phosphate rock is surface mining. Surface mining consists of clearing the site of brush, initial removal of topsoil and overburden, ore removal, and reclamation. Eastern phosphate comes from surface mining and is sometimes extracted through a mechanized

There are three main types of phosphate rock in China, namely, magmatic phosphate rock, sedimentary phosphate rock, and sedimentary metamorphic phosphate rock, while 70% to 80% of which is sedimentary phosphate rock deposits. The composition of GL2-3# is typical of low-grade sedimentary dolomitic sedimentary phosphate rock containing rare earth.

The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.

Phosphate Ore Mining Electrically operated drag lines strip off the overburden from the mining area and deposit the phosphate matrix around a pump pit. Here it is sluiced with streams of high pressure water to the suction of a large centrifugal pump which transports the matrix slurry to the washing plant which may be a mile or two away.

The 2 major western phosphate rock ore deposits are located in southeastern Idaho and northeastern Utah, and the beneficiation processes used on materials from these deposits differ greatly. In general, southeastern Idaho deposits require crushing, grinding, and classification.
