The Manufacture of Sulfuric Acid and Superphosphate

I-Chemicals-B-sulfuric acid-1 THE MANUFACTURE OF SULFURIC ACID AND SUPERPHOSPHATE Superphosphate is the fertiliser most commonly used in New Zealand to ensure that soil has a sufficiently high phosphorous c ontent. It is manufactured from the reaction between sulfuric acid and ’phosphate rock’ (rock rich in the mineral fluorapatite, Ca5(PO4 ...

Sulfuric Acid in the Phosphate Fertilizer Industry - Clean ...

Sulfuric acid is used as a key first step in the production of both MAP and DAP, after which it is mixed with phosphate rock to produce phosphoric acid. And since the phosphoric acid production process consumes energy, an on-site sulfuric acid plant – a net producer of energy – is a critical part of the fertilizer production process.

History of Phosphate Fertilizer Production

Sulfuric Acid: This acid is produced at phosphate plants for use in reacting with phosphate rock to produce phosphoric acid. The heat generated off sulfuric acid production is used to power phosphate manufacturing plants and extra energy is often sold back to the area electric grid. Some sulfuric acid may be sold separately as a product.

Phosphate Rock and Sulfuric Acid | SpringerLink

高达10%返现 · 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.
