BEN GUERIR (RU: Бен-Герир) is the deposit of phosphorites within Morocco, within the Gantur region. It has been discovered during the 1963.
The phosphorite-bearing depositions (Maastrichtian-Eocene) with the thickness of 114-218 metres are distributed within the Bahira Tadla synclinal structure with the length of up to 125 kilometres, with the width of 10-25 kilometres. Within each of the Maastrichtian and Eocene depositions, there are distinguished three industrial layers with the thickness of 1.4-2.1 metres, with the content of P2O5 of 23.5-32%.
The phosphorites are grainy, carbonatic, and siliceous-carbonatic. The reserves are 900 million tonnes of the ore, of which the ones, which have been explored for the open pit extraction, are 136 million tonnes (1980). The technological scheme for the beneficiation of the phosphorite ores prescribes the stages of the crushing and screening, initial washing (for the removal of clay and part of carbonates), calcined roasting, and secondary washing (for the removal of lime). The produced concentrate contains approximately 34% of P2O5. On the base of the deposit, there is contemplated the creation of the third (after the Khouribga and Yusuf) phosphorite-extracting centre within Morocco. The productive capacity of the mine is 2-3 million tonnes of the ore (1980).
