gypsum beneficiation process

Beneficiation of Raw Gypsum Ore – 2020 SURP Symposium

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.

Processing and Drying Gypsum

2019-4-11  Gypsum dryers work as moisture control solutions. A rotary dryer is used to reduce the moisture content of the gypsum. Lifting flights inside the rotating drum shower the gypsum through a heated air stream, drying the material as it moves through the dryer. Drying is also part of the beneficiation process, separating the desired material

2014-4-21  Beneficiation The fast movement of the slurry causes it to bang against the pipes, and this breaks apart any clay balls. What arrives at the beneficiation plant are fine-grained sand, clay and phosphate sediments suspended in water. At the beneficiation plant, the slurry is first run through a screen, which filters out the coarser sand.
