The sulphates and some of the gypsum dissolve almost instantly, which gives rise to a highly alkaline sulphate solution. The most reactive non-soluble components then start to react with the water. These are usually minerals that contain aluminium, which react to form aluminate gels. This process normally occurs in a few minutes and produces a lot of heat (I) (Figure 3).

The fractured gypsum is then loaded onto trucks and transported to a processing plant. At the processing plant, the large gypsum ore is reduced in size by passing it through a large crusher. Crushing the ore generates a mixture of smaller rocks that can be cleaned and sorted by size.

This process is used because it does not require electricity or water to run. Sieving is used to separate particles by size. 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.
