Phosphate Rock Deposit
What Are Phosphorus Rocks?
· Phosphate rock deposits can be sedimentary (formed from sediment deposited by water or air) or igneous (having solidified from lava or magma). However, the easiest way to obtain phosphorus is by way of mining and concentrating phosphate rock from the phosphate deposits. Used in fertilizers ; Worldwide, more than 85% of the phosphate rock mined is used to manufacture phosphate .

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. Pure phosphorus is used to make .

Phosphate Rock Statistics and Information
Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogenphosphoruspotassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus. The United States is the world's leading producer and consumer of phosphate rock, which is

Phosphate rock is an imprecise term that describes naturally occurring geologic materials (minerals) that contain a relatively high concentration of P. The term PR is used to describe raw (unbenefi ciated) phosphate ores, but may also be applied to beneficiated or concentrated products . Phosphate rock occurs in both sedimentary and igneous deposits across the world (Figure 1). Most (80 to 90 ...

Countries With the Largest Phosphate Reserves
· Phosphate rocks are found across the world both in sedimentary and ingenious deposits. Phosphate is used to produce fertilizer that is essential in replacing the phosphorous that is removed by plants from the soil. Phosphate rocks are mainly mined by split technology. However, a significant amount of deposits in countries such as China and Russia are extracted by underground mining. In .
Sedimentary Phosphate Deposits Mineral Deposit Profile F07
DEPOSIT FORM Phosphatebearing rocks are generally stratiform; bed thicknesses range from less than 1 metre to tens of metres and may extend for distances up to several hundreds of kilometres in their longest dimension. The thickest deposits are amalgamated/condensed beds (tabular units) reflecting variations in upwelling intensity and storm frequency through time. Individual phosphorite ...

· Igneous deposit vs sedimentary deposit. Phosphate rocks are classified into two groups based on the geological origins: • Intrusive rocks of igneous (or magmatic) origin: consist of mafic to ultramafic rocks (nelsonite of Lac à Paul) or alkaline rocks (phosphorous carbonatites). • Sedimentary rocks : these deposits are generally sandstone coming from ancient skeletal of millions of marine ...

Phosphorite
Phosphorite, phosphate rock or rock phosphate is a nondetrital sedimentary rock that contains high amounts of phosphate phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.
Loions of Deposits
Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks.
