1121 Phosphate Rock Processing 11211 Process Description15 The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475 Theby reacting sulfuric acid (H2SO4) with naturally occurring phosphate rock The phosphate rock is dried, crushed, and then continuously fed into the reactor along with sulfuric acid The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (CaSO4), commonly referred to as gypsumAP42, CH 89: Phosphoric Acid

Applications and functions of foodgrade phosphates

Phosphate rock is mined all over the world with the largest reserves of high purity originating in Morocco1 The mined and crushed rock is reacted with sulfuric acid followed by a solvent extraction of the phosphoric acid and release into an aqueous phase The acid is dearsenified and deflourinated, resulting in foodgrade phosphoBone meal and rock phosphate are typical sources If you can find them, fish bone meal and soy husks are other good sources And then there is compost :) Composted yard waste and manures generally provide all the phosphorus normally required by most plants in most soils and if applied in excess, can create an oversupplyHow to Make Phosphorus Rage University

Crushing in Mineral Processing

In mineral processing or metallurgy, the first stage of comminution is crushing Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks In principle,Phosphate rock is an unprocessed ore that contains apatite, or a group of calcium phosphate minerals Once the mineral is processed, the phosphate can be readily usedWhere is Phosphorus Found & How is it Obtained? |

Rock Phosphate How To Crush

Use of phosphate rocks for sustainable agriculture

Consolidated rocks need to be crushed and ground in order to liberate the phosphate particles Usually, a rock has to be ground to about onehalf the grain diameter of the mineral particle of interest or primary gangue mineral in order to achieve the liberation (80 percent monomineral particles) needed for beneficiationPhosphate rock and/or fines A light brown to white rock which is sometimes crushed to make the phosphate fines Varies in texture from a sandy powder to a lumpy material containing a large proportion of dust, and due to its freeflowing properties considerable loss may arise inPhosphates and Superphosphates Cargo Handbook the
