8.9 Phosphoric Acid 8.9.1 General1-2 Phosphoric acid (H3PO4) is produced by 2 commercial methods: wet process and thermal process. Wet process phosphoric acid is used in fertilizer production. Thermal process phosphoric acid is of a much higher purity and is used in the manufacture of high grade chemicals,

A primary objective of the beneficiation process is to reduce the silica content in the ore, as the latter reacts with caustic soda during the digestion step to precipitate out as insoluble sodium aluminium silicates, e.g. 2Na2O.2Al20;,.3Si02.2 H20. This salt is eliminated from the process along with the insoluble iron and

According to the different properties of iron ores, their beneficiation methods are also different. Mineral Processing The iron ore dressing process is aimed at the processing of iron ore materials, which is divided into crushing and screening, grinding and classification, separation, and dehydration.
