The ore is a volcanic phosphate ore containing approximately 20 %P 2O 5 (27% to 28% CaO) primarily as apatite. Principal impurities are barite (9% to 15% BaSO 4), hematite (19% to 20% Fe 2O 3), alumina and silicates occurring as quartz, micas and clays. The barite is removed in a preflotation step using cetyl stearic sulphate as a collector.

AbstractPhosphoric acid (H3PO4, 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%P2O5 acid.
