Highlights on the beneficiation trials of the Egyptian phosphate ores

Most deposits which can be mined and processed economically to produce a concentrate with a grade of about 28-38% p2o5 are considered commercial phosphate deposits. because of the increasing world demand, the grade of a great portion of the mined phosphate deposits is declined and many low-grade phosphate deposits became economically mineable. methods and techniques used in the processing of ore are depending on its grade, type and quantity of gangues associated with the phosphate mineral. phosphate deposits in Egypt occur with large quantities in the Nile valley, red sea, and the new valley areas. therefore, the main objective of this review is to shed some light on the locations, reserves, and the beneficiation trials of the different localities of the Egyptian phosphate ores, with focusing on water conservation in the dressing plants and positive uses of solid wastes. it is recommended to use the bio-flotation, column flotation, and the new types of reagents, as recent trends to upgrade the Egyptian phosphate ores. it is also advised to pay attention towards the recovery of phosphate from its slimes.
