Phosphate ore processing for phosphoric acid production ...

2013-11-29 · Abstract. Phosphoric acid (H 3 PO 4, PA) is an industrial acid, produced from two main types of phosphate rock: sedimentary and igneous.In the classical wet process, wet process PA is produced by a reaction between the ore and sulphuric acid, forming 30% solids thick slurry, in three stages: acidulation, filtration and concentration to produce a 50%P 2 O 5 acid.

25.2 Extracting ores | Mining of mineral resources | Siyavula

Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start.
