Phosphate Rock an overview ScienceDirect Topics

Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.

"The Recovery of Rare Earth Elements from Phosphate

In this study, the extraction and recovery of rare earth elements and phosphorus from phosphate rock and three phosphate fertilizer waste by-products, phosphogypsum, amine tailings, and waste clay, using 2.5% nitric acid and a novel water-insoluble adsorption polymer, poly (maleic anhydride-alt-1-octadecene) sodium salt, are examined.

Phosphate Rock norganics

Phosphate Rock. Phosphate Rock is an excellent natural source of phosphorus, calcium and many essential trace elements. It contains over 30 percent total phosphate (3-8 percent available) and 48 percent calcium (as CaO). Phosphate rock has approximately one fifth the neutralizing power of lime.

Phosphorus is one of the essential nutrients required for plant growth. Although it is moderately available in nature, it is a deficient nutrient in most soils especially calcareous soils. Phosphate rock (PR) is considered the cheapest P fertilizer. Phosphate rock sources may be of igneous or sedimentary origin.

The radioactivity of phosphate rock was probably first observed in 1908, when the British physicist R. Strutt found that samples of phosphorite were many times more radioactive than the average rocks of the Earth's crust. 23 The dominant radioactivity detected in phosphate rocks are uranium, thorium and their decay products in equilibrium with

Despite the abundance of phosphorus in both organic and inorganic forms in the soil, it is mostly unavailable for plant uptake due to its complexation with metal ions in the soil. The use of agrochemicals to satisfy the demand for phosphorus to improve crop yield has

Overview of Phosphate's Role in the Body Hormonal

Phosphate is one of the body's electrolytes, which are minerals that carry an electric charge when dissolved in body fluids such as blood, but the majority of phosphate in the body is uncharged. (See also Overview of Electrolytes.) Bone contains about 85% of the body’s phosphate. The rest is located primarily inside cells, where it is
