Beneficiation of Raw Gypsum Ore
The calcium bentonite clay in the raw gypsum ore has a particle size of ~1-5 µm, whereas the gypsum and quartz have a particle size of ~1-2 mm. Therefore, the calcium bentonite clay can be separated through sieving. Sieving is cost-effective; however it is not the most effective beneficiation process as some impurities remain after sieving.
