2021-2-4 A new phosphate rock mine began operation near Spanish Forks, UT, in July 2020. The operating company will market its phosphate rock for direct application to soil for organic farming. Production initially was to be about 5,000 tons per year, eventually increasing to 48,000 tons per year after 5 years. The mine site was developed in the

Phosphate rock is obtained from geological deposits. Its primary constituent is apatite, a calcium phosphate mineral. Phosphate rock is the basis material for almost all phosphate fertilizers, either as such or transformed into phosphoric acid. When added to the soil, phosphate rock slowly dissolves and gradually releases its nutrients.

2019-2-13 Variscite is a hydrous aluminum phosphate, Al(H 2 O) 2 (PO 4), with a Mohs hardness of around 4. It forms as a secondary mineral near the surface in places where clay minerals and phosphate minerals occur together. As these minerals break down, variscite forms in massive veins or crusts. Crystals are small and very rare.
