Reaction Of Phosphoric Acid With Phosphate Rock

Image

Understanding phosphorus fertilizers

1 Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils. However, very little rock phosphate is currently used in agriculture due to low availability of P in this native material, high transportation costs and small crop responses.

However most phosphoric acid needed to make fertilizers need not be very pure and is more cheaply made directly from rock phosphate ores and not via the element. Elemental phosphorus is also used to manufacture other chemical intermediates (products used in the manufacturing processes for other chemical products).

Phosphate Rock and Sulfuric Acid

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.

1991/08/01A detailed investigation of two phosphate rock acidulation modes has been carried out in batch acidulators. The classical dihydrate process rate is affected by the coating of the rock particle by gypsum. The clean phosphoric acid process using phosphoric acid as an acidulation agent does not suffer from this inhibitory coating effect, however it is affected by the increasing viscosity of the

How is phosphoric acid most commonly produced?

Defoamers for phosphoric acid production in this way is most commonly called producing phosphoric acid through the wet process. Why is there foam in phosphoric acid production? There are typically many answers to this question and that is primarily because a lot of the foam depends on the kind of phosphate rock that is being used in the reaction.

Phosphate Rock And Sulfuric Acid

Treating phosphate rock with sulfuric acid produces phosphoric acid, the water-soluble material from which most phosphate fertilizers are derived. The process involves dissolution of phosphate rock in an aqueous mixture of phosphoric and sulfuric acid and subsequent crystallization of calcium sulfate dihydrate from the product phosphoric acid solution.
