How phosphate is mined and processed

Therefore, spreading phosphate rock on fields had little effect on plant growth. However, in the mid-1800s, chemists discovered that mixing sulfuric acid with phosphate rock would make a soluble fine powder called superphosphate; this discovery turned phosphate rock into the valuable fertilizer it is today. A caveat, however, is that once

Processing Phosphates for Use in the Fertilizer Industry

In a wet process facility, phosphoric acid is produced by reacting sulfuric acid (H2SO4) with naturally occurring phosphate rock. The phosphate rock is dried, crushed, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (CaSO4), commonly

acid to form a mixture of soluble mono-calcium phosphate and calcium sulphate (approximately 9% phosphorous) which is able to be used by plants. In many other parts of the world it is more cost effective to use triple superphosphate fertiliser. In this process phosphate rock is reacted with phosphoric acid to produce a product with 21% phosphorous.
