Phosphate rocks, also referred to as phosphorites, are sedimentary deposits with high phosphorus (P) concentrations. These rocks are one of the primary ore sources for P (Fig. 1), which in turn is a critical and non-renewable element for fertilizer production, upon which global fertility depends.The startling limitation of phosphate rock reserves has led …Web
Introduction. Phosphate rock and phosphate fertilizer are sources of elemental phosphorus which increases both soil fertility and crop yields (Mogollón et al. 2018; Hellal et al. 2019).Phosphate rock, pre-concentrated phosphate ore, can contain elevated concentrations of naturally occurring uranium that Bunus estimated to largely be in the …Web
