  • Rock Phosphate

    Rock Phosphate should be plowed under or turned into the soil. Unlike chemically made phosphates, rock phosphate is insoluble in water, will not leach away, and therefore is long-lasting. Annual plants absorb up to 60 percent of its total phosphate needs within the first few weeks of its life.

  • What is phosphate and how is it used?

    Phosphate is a sedimentary rock formed millions of years ago by the accumulation of organic matter on the ocean floor. Phosphate reserves are found in Africa, North America, Kazakhstan, the Middle East and Oceania but the world's largest deposits are located in Morocco, which is also one of the global leaders in phosphate extraction.

  • Apatite: The mineral apatite information and pictures

    Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. (These biological Apatites are almost exclusively the Hydroxylapatite type.) Chemical Formula.

  • Phosphate Rock

    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

  • 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. Natural rock phosphates are from deposits of apatite rock formed

    Mar 03, 2019Each year, an estimated 250 million tons of phosphate rock are mined to produce phosphoric acid for fertilizers. The U.S. mined approximately 28 million metric tons in 2017. Rare earth elements generally amount to less than 0.1 percent in phosphate rock. But worldwide, about 100,000 tons of these elements per year end up in phosphogypsum waste.

Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F. Other members of the apatite group have chlorine or hydroxyl that take the place of the fluorine

  • Phosphate Rock

    Phosphate rock comes from geologic deposits located around the world. Its main constituent is apatite, a calcium phosphate mineral primarily extracted from sedimentary marine deposits, with a small amount obtained from igneous sources. Most phosphate rock is recovered through surface mining, although some is extracted from underground mines.
