Phosphate Rock an overview ScienceDirect Topics

Rock phosphate, the primary raw material for fertilizer and phosphoric acid, occurs as high-grade ore (+30% P 2 O 5), medium-grade ore (20%–30% P 2 O 5), and low-grade ore (15%–20% P 2 O 5). The very high-grade ore blends with medium-grade ore for direct sale. The high-grade ore is mined, crushed, and sold to various fertilizer plants.

11.21 Phosphate Rock Processing

11.21 Phosphate Rock Processing 11.21.1 Process Description1-5 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. The 6-digit Source Classification Code (SCC) for

Processing Phosphates for Use in Animal Feed

Phosphoric acid and limestone (calcium carbonate) are fed into the high speed mixer. The mixer is comprised of a vertical chamber with a paddle shaft running through the middle, which rotates at 300-400 RPMs to create an intense mixing action.

Phosphate conversion coating Wikipedia

It serves as a conversion coating in which a dilute solution of phosphoric acid and phosphate salts is applied via spraying or immersion and chemically reacts with the surface of the part being coated to form a layer of insoluble, crystalline phosphates. Phosphate conversion coatings can also be used on aluminium, zinc, cadmium, silver and tin.

What is Phosphating? Definition from Corrosionpedia

Phosphate coatings are usually applied to carbon steel, low-alloy steel and cast iron. The coating is formed with a solution of iron, zinc or manganese phosphate salts in phosphoric acid, and is applied by either spraying the solution onto the substrate, or immersing the substrate into the solution.

The Manufacture of Sulfuric Acid and Superphosphate

The phosphate rock mixture is passed through a hammer mill which reduces the particle size to 0.5cm or less. The coarsely ground rock is then passed through an air swept roller mill (Bradley Mill) to attain a rock grist of approximately 75% less than 75 microns. The powdered rock is stored in a large hopper.

Phosphate process United States Gypsum Company

A process for the recovery of phosphate values by chemical leaching from a phosphatic-mineral-containing souce material comprising the steps of: 1. forming an aqueous leach acid mixture of sulfuric acid and a second acid selected from the group essentially consisting of hydrochloric acid and nitric acid, in approximate proportions of about 3/4 mole of the second acid, about 11/8 mole sulfuric

US4577804A Wet grinding phosphate rock in an acidic

Phosphate rock contained in an acidic slurry is ground by equipment wherein the acidic slurry contacts the metallic surfaces of the equipment. A method for monitoring and controlling grinding ball consumption is provided in which acid-neutralizing particulate iron contained in the acidic slurry is measured and correlated to control curves, which relate particulate iron concentration to slurry

US4207301A Process for producing zinc phosphate

A process for producing zinc phosphate comprising treatment of zinc oxide with phosphoric acid in an aqueous medium at a temperature ranging from 70° to 80° in the presence of metallic zinc taken in an amount of from 1 to 10% by weight of zinc oxide, followed by separation of the resulting residue of zinc phosphate. It is possible to introduce zinc oxide and metallic zinc into the treatment

Chemical Processing of Phosphate

The sulfuric acid that is needed to convert the phosphate rock into phosphoric acid is also produced at the chemical processing plant using liquid (molten) sulfur, most of which is shipped to a Florida port and trucked to the processing plants. Since the energy crisis in the 1970s, most Florida phosphate companies capture the heat released in the burning of sulfur and production of sulfuric

Bismuth phosphate process Wikipedia

The bismuth-phosphate process was used to extract plutonium from irradiated uranium taken from nuclear reactors. It was developed during World War II by Stanley G. Thompson, a chemist working for the Manhattan Project at the University of California, Berkeley.This process was used to produce plutonium at the Hanford Site.Plutonium was used in the atomic bomb that was used in the atomic

The Manufacture of Sulfuric Acid and Superphosphate

This sulfuric acid is then used to produce superphosphate, with the excess being used in the production of aluminium salts or sold directly as sulphuric acid. The superphosphate is also produced in a three step process. Step 1 Phosphate rock blending and grinding The phosphate rock is ground until at least 75% is less than 75 ˜m (microns) in

Sugar Refinery : Melt Phosphofloatation Sugar Mill

The Phosphofloatation process removes turbidity and colour from refinery melt liquor. Phosphoric acid and lime are dosed to produce a calcium phosphate precipitate which scavenges colour and this performance is enhanced through the addition of colour precipitant which reduces the colour by 50%. Screened sugar liquor is pumped from the Untreated Liquor Tank via an automatic flow control valve
