2015-9-10  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

Processing Phosphates for Use in the Fertilizer Industry

The dried phosphate ore is then most commonly processed into what are referred to as ammoniated phosphates. This is done by reacting the phosphate rock with sulfuric acid to produce phosphoric acid. The phosphoric acid is then reacted with ammonia to produce the ammoniated phosphate MAP or DAP.

1992-1-1  Process Technology of Phosphoric Acid. There are two main commercial processes to produce phosphoric acid: the wet process and the dry (electrical furnace) process.Although, the acid produced (technical grade) with the dry process is pure, its production cost is much higher than that of the wet process phosphoric acid (WPPA or fertilizer grade acid).

Environmental impact of phosphate mining and

Phosphorus is common within geological materials. The average continental crust contains 0.27% P 2 O 5. 1 Phosphorus is the primary resources to produce fertilizer and phosphorous-based products. 2 Phosphorus is neither substitutable nor recyclable, therefore, the total demand must be provided through the mining, beneficiation and chemical processing of phosphate ores.

Phosphate facts

The countries with the largest reserves of rock phosphate are Morocco, China and Algeria, with Morocco owning 70% of known reserves. There are only about a dozen countries that export phosphate rock, because the rock is often produced and kept by countries like China and the USA to produce food to feed their own people.
