The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of important parts of manufacturing process ...
Beneficiation of phosphate ore is a process which includes washing, flotation and calcining. Froth flotation is used to concentrate the mined ore to rock phosphate. The mined ore is crushed and washed, creating a slurry, this ore slurry is then treated with fatty acids to cause calcium phosphate .
chemical processing of phosphate ores. The key to understanding the association between environmental pollution and phosphate rocks lies in appreciating the mining and processing effect of phosphate ores. Phosphorus is normally produced by mining and beneficiation of Phosphate ores. 3 Mines produce large amounts of waste including toxic

Beneficiation of Saudi phosphate ores by column fl . The chemical analysis of the rock revealed that P 2 O 5 = 251%, CaO = 527%, SiO 2 = 117% and CaO:P 2 O 5 ratio = 21 The main problem of this ore is its high content of calcite mineral The separation of such calcite gangue from apatite phosphate mineralis the main target of this beneficiation process
Phosphate beneficiation is carried out at the phosphate beneficiation Plant at Al-Qaim Fertilizer Complex to raise the content of P 2 O 5 from 19-20 % to about 30% through the calcination process.
The beneficiation of phosphate rock can often be simplified and made more economic by taking into account the distribution of P 2 O 5 and impurities as a function of their deportment between the size fractions resulting from mined and comminuted sedimentary phosphates.
