When underground mining became uneconomical, black phosphate mines were simply left abandoned and in the nineties, the underground exploitation in Youssoufia gave way to open-pit mining. In 1979, OCP began open-pit phosphate exploitation in the Benguerir mine site which is considered the most recent of the four mine sites in Morocco.

The wastes of phosphate ore are mostly of lower grade which needs processing or upgrading for economic utilization. Phosphate ores in terms of quality and P 2 O 5 grade can be divided into three groups: low-grade (12-16% P 2 O 5 ), intermediate-grade (17-25% P 2 O 5 ), and high-grade (26-35% P 2 O 5) [7].
