Phosphate exists in both sedimentary and igneous rock types. Sedimentary rock forms from layers of sediment and organic matter, while igneous rock originates from cooled magma or lava. Interestingly, igneous phosphate rock deposits have the advantage of producing higher-purity phosphoric acid suitable for EV battery production, …

High-grade deposits formed as a result of hydraulic concentration of phosphate grains to form granular beds with minimal gangue. The amalgamation of these beds into decameter-thick, stratiform ore zones is generally focused along the maximum flooding surface, which is a primary exploration target in upwelling-related phosphorite.

Significant sedimentary deposits of phosphate rock occur in Idaho, Utah, and, to a lesser degree, Wyoming and Montana. The quality of phosphate rock is most often expressed in P 2 O 5 content, and some of the world's richest phosphate rock deposits contain 30 percent P 2 O 5 or better. Utah contains some of these rich deposits, but some of ...

Underground mining tends to be more costly and therefore less common for phosphate deposits than surface mining. Because 1 ton of phosphate rock has only about 10 percent of the commercial value of 1 oz of gold, low-cost mining is imperative. Sedimentary phosphate deposits are exploited by underground mining in China, …

Phosphorite (often referred to as phosphate rock) is a sedimentary rock of which the main mineralogical constituent is francolite (carbonate-fluor-apatite, CFA). The above definition excludes igneous phosphate-rich rocks as well as continental deposits (e.g., guano; a few lacustrine deposits) Whereas most sedimentary rocks contain less than 1% ...
