Phosphate rock contains the mineral phosphorus, an ingredient used in some fertilizers to help plants grow strong roots. Phosphate rock contains small amounts of naturally-occurring radionuclides, mostly uranium and radium. When processing phosphate rock to make fertilizer, the phosphorous is removed by dissolving the rock in an acidic solution.

Phosphate is mined for its life-giving capabilities to plants, animals, and humans in the form of phosphorus. A key component in crop production, livestock feed, and even in consumer products, in 2019 alone, world phosphate rock production was at 240 MT. Just as with any mineral, phosphates can present challenges during processing.

At the beneficiation plant, the phosphate is separated from the sand and clay. The phosphate is sent by rail to a separate chemical processing plant where it is processed for use in fertilizer and other products. The chemical processing is done at separate facilities that are not regulated by the Mining and Mitigation Program.

Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.

OCP moved into downstream processing in 1965, converting lower-grade rock to phosphoric acid and fertilisers at its plants at the coastal town of Safi. In 1975, Maroc Phosphore was established as a subsidiary of Groupe OCP, primarily to add value to more rock and to export intermediate phosphate products.

Chemical processing is necessary because phosphate rock is not watersoluble. Approximately five tons of phosphogypsum are produced for every ton of phosphoric acid produced. This processing by-product must be stockpiled in stacks per a 1989 EPA rule that banned its use because of the trace amounts of radioactivity in the substance.

When phosphate rock is added to soil, it slowly dissolves to gradually release nutrients, but the rate of dissolution may be too slow to support healthy plant growth in some soils. To optimize the effectiveness of phosphate rock, consider these factors: Soil pH. phosphate rock requires acid soil conditions to effectively nourish crops.
