Method for manufacture of phosphoric acid from phosphate rock

Aug 22, 1978 · A number of processes are known for the conversion of phosphate rock into phosphoric acid and other valuable phosphorus containing materials. Generally, there are based on the formation of mono calcium phosphate, CaH 4 (PO 4 ) 2 which is a water soluble compound.

Phosphate - Wikipedia

A Phosphate is a stone derivative of phosphoric acid.The phosphate ion (PO 4) 3− is an inorganic chemical, the conjugate base that can form many different salts.In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid. Of the various phosphoric acids and phosphates, organic phosphates are important in biochemistry and biogeochemistry (and, consequently, in ...


Phosphate rock has up to one fifth the neutralizing power of lime; It is an Australian mined and refined product. We sell soft phosphate and reactive phosphate rock (RPR) in powered or granules both in straights or blended with products like gypsum, biology, sulphur, lime, compost and humates.

Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. ... This conversion is rapid and, with normal soil temperatures, can be completed in days or less. An enzyme called pyrophosphatase, which is abundant in most soils, enhances this conversion process. Comparing products.

Phosphorite - Wikipedia

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, de-liming, magnetic separation or flotation.
