Phosphorite - Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% 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 ...

Phosphate Rock and Sulfuric Acid | SpringerLink

Abstract. Phosphate rock and sulfuric acid are the two major raw materials for manufacture of phosphate fertilizers. Nearly all commercial phosphate fertilizers are derived from phosphate rock; the major exception is basic slag which derives its phosphorus indirectly from phosphate minerals that are present in iron ore or deliberately added to the iron blast furnace charge.

Eaters of the earth: the terrifying, overlooked story of ...

Apr 22, 2020· The case hinges not on mining, but on what happens after the rock leaves the mine: chemical processing. Phosphate rock is shipped to plants where it is treated with sulfuric acid, yielding phosphoric acid, which in turn is treated with ammonium to create a water-soluble fertilizer. For every ton of phosphoric acid, this process yields five tons ...
