WebThe phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% [1] to 20% phosphorus pentoxide (P 2 O 5 ). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5. This occurs through washing, screening, de-liming, magnetic separation or flotation. [1] WebPhosphate includes several naturally occurring minerals that contain phosphorus as well as other elements. It is primarily used to produce fertilizers for food production. It may also be used in animal feed supplements, food preservatives and many industrial products. Where is phosphate mined in Florida?
