Rotary kiln. Calcination in a rotary kiln is a direct, long-time calcining process. During the process, the phases of the CaSO 4 x H 2 O system can be optimally adjusted. Rotary kilns are used for the calcining natural gypsum. In this process, pre-crushed natural gypsum is calcined in parallel flow with the flue gas.
An et al. 83 proposed this process for treating brines from Salar de Uyuni (Bolivia), which involves the use of lime to first precipitate Mg as hydroxide (Figure 3.3). Gypsum (CaSO 4 ·2H 2 O) and B (as borate) are also coprecipitated with Mg(OH) 2. The mixed slurry has to be further processed to recover Mg.

Gypsum is a very useful processed material. Gypsum rock was formed in geological time through the evaporation of seawater. More recently by-product gypsum is also available from flue gas desulphurisation; a process for cleaning up emissions from chimneys to reduce the quantity of sulphurous gases flowing into the atmosphere.
The main strengths of the group are the supply and processing of water, the recovering of raw materials from waste, the development of recycling products and the provision of alternative energy sources. In another business segment, gypsums from flue-gas treatment and industrial processes are processed into top-grade gypsum binders.
