Phosphorite, or phosphate rock, is the raw material of phosphoric acid production. It has also been regarded as the most important secondary rare earth element (REE) resource due to low contents of rare earth elements contained in the ore. In Florida, there is about 19 Mt of phosphate rock mined annually. After beneficiation, the …

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.

In Huelva, these industries use the "dihydrated" process to obtain phosphoric acid, whereby the phosphate rock is treated chemically with sulfuric acid. This process can be described by means of the following reaction [3]: Ca 10 (PO 4 ) 6 F 2 + 10H 2 SO 4 + 20H 2 O → 10(CaSO 4 2H 2 O) + 6H 3 PO 4 + 2HF

Wet-process phosphoric acid is one product of the reaction between phosphate rock and sulfuric acid. The limiting step in this process occurs when the acid is filtered from the reaction slurry, which also contains calcium sulfate (gypsum). The acid-soluble impurities present in the phosphate rock (e.g., fluorine, silicon, and aluminum) form complexes in …
