An Overview of Phosphates and Their Uses

Orthophosphates are the simplest form of phosphate and are sometimes called monophosphoric acids. In this form, three hydrogen atoms are bonded to the oxygen atoms in the phosphate structure. This simplest form of phosphate is very commonly used in detergents.

Each 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.

Understanding phosphorus fertilizers

Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils. However, very little rock phosphate is currently used in agriculture due to low availability of P in this native material, high transportation costs and small crop responses.
