More than 40 countries are extracting phosphate rock from phosphate deposits. China, Morocco, USA, and Russia are the top four phosphate producers, accounting for around 79% of the total global production (Ruan et al., 2019). The countries producing more than 1 Mt/year are presented in Fig. 1 (USGS, 2022).

In Morocco, phosphate stands out as a strategic resource (Fikrat et al., 2023 ): in 2020, 23% of extracted and washed phosphate rock, 27% of produced phosphoric acid and, a signi cant 96% of the manu-
In Morocco, the open-pit phosphate mines extract the sedimentary phosphate using the discontinuous panel extraction process. During this operation, the overburden and intercalation layers are extracted and stored in piles. The sandy phosphate is extracted using bulldozers and transported to treatment and beneficiation plants.

Morocco is facing water shortage due to increasing water demand and low precipitation induced by climate change (Taheripour et al., 2020). However, the floating process, a widely used beneficiation technique for phosphate rocks, consumes a large amount of water (Reta et al., 2018; Ruan et al., 2019). This has aggravated Morocco's water crisis.
For the beneficiation of Khouribga region rock phosphate ore, a phosphate concentrate containing 31.05% of P 2 O 5 was obtained with a recovery of 98.21% at pH 5. Similarly, a concentrate assaying at 32.39%P 2 O 5 with a …

Phosphate rock normally is used as a dry rock or in slurry form. However, in some cases, particularly where the raw phosphate is high in carbonaceous matter or it is desirable to have a clean acid, the rock is calcined. Also, in a few cases, the phosphate rock is calcined, the product slaked, and free lime separated as a beneficiation step.
