Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer.
As high grade deposits of phosphate rock are being depleted day by day in the world, future sources will be derived from low grade rocks containing various impurities. Low grade phosphate rocks are not suitable for direct use in acidulation plants unless their tricalcium phosphate (TCP) content is increased to 70% or more, using conventional methods …
The phosphate recovery chain can be divided into three processes. Starting with the extraction process where the phosphate rock is separated from the associated minerals of guange and sent to the beneficiation plant. In this second process, the phosphate rock is concentrated using physical and chemical separation methods.

Beneficiation of Phosphate Ore examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum …
The results of this study revealed that column flotation technology is a promising tool for beneficiation of calcareous phosphate ores. A high purity ore of 35% P 2 O 5 can be easily achieved at a high recovery value of 95% starting from a rock contains 25% P 2 O 5, high calcite content (52.7% CaO) and CaO:P 2 O 5 ratio equals 2.1.
