Beneficiation of phosphate ores

A process for beneficiating phosphate ores in which the ore is scrubbed and deslimed prior to separation into a coarse fraction and a fine fraction, each of which is subjected to a plurality of anionic flotation steps and screening steps to obtain high recovery and high grade phosphate product whereby the acid cleaning and cationic flotation steps previously used are eliminated.

builders of phosphate beneficiation

Beneficiation of phosphate ores by dry electrostatic processes has been attempted by various researchers since the 1940's. The underlying reasons for developing dry processes for phosphate recovery are the limited amount of water in some arid regions, the flotation chemical costs, and the wastewater treatment costs.

The acid vapors can be condensed or washed with water for recycle. The residue, which typically analyzes 40% P 2 O 5, is insoluble in water but soluble in citric acid and can be marketed as a fertilizer or as a high-grade phosphate product. Since calcium chloride is a waste product while calcium nitrate is a fertilizer, nitric acid is preferable as a leaching agent (Figure 6).

phosphate ore beneficiation

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.
