Gypsum slurry mostly dewatered by a two-stage process: 1. Slurry is pre-thickened and partly classified by a set of hydro-cyclones in first step. Though not very common, static thickeners can be used alternatively. 2. Further dewatering and cake washing in second step. water content of commercial grade gypsum needs to be below 10% wt.

The final FGD waste is wallboard-grade gypsum. Limestone Forced Oxidation Flue-Gas Desulfurization Process Note: FGD = flue-gas desulfurization By controlling the gypsum quality in the dewatering step, a wallboard-grade gypsum can be produced. The majority of scrubber installations in Europe and Japan generate gypsum for reuse.
Gypsum rock when heated to 100-190°C looses ¾ of its H 2 O CaSO 4.2H 2O → CaSO 4.½H 2 O + 3/2 H 2 O Plaster of Paris This low burning process is INCOMPLETE CALCINATION. When calcination is carried out at temperatures above 190°C all water is removed. CaSO 4.2H 2O → CaSO 4 + 2H 2 O gypsum anhydrite This high-burning process is COMPLETE

The MET AS WFGD process is similar to the more familiar limestone/gypsum WFGD process as illustrated in Figure 1. In fact, many components are common between these two processes, such as the absorber vessel, recycle pumps, spray nozzles, etc. The equipment components which differ are reagent handling and dewatering.

The term "synthetic gypsum" has been used widely to encompass materials produced by a variety of industrial processes. In addition to FGD gypsum, synthetic gypsum includes materials such as phosphogypsum, (a byproduct of processing phosphate ore to make phosphoric acid), Titanogypsum (a byproduct from the production of titanium dioxide), fluorogypsum (a byproduct from the production of
Jan 02, 2020· The thing about drywall is that gypsum gets sandwiched between two layers of heavy paper which helps to prevent the board from breaking. However, plasterboards are composed not only of gypsum: even though manufacturers balance between 70 to 95% gypsum, cellulose and additional substances may comprise up to 30% of the material’s composition.

A copper smelting process is disclosed in which copper concentrate is smelted in a furnace to produce purified copper. Flue gas discharged from the furnace is treated to produce sulfuric acid. Furthermore, waste liquid discharged during the production of sulfuric acid is treated to produce gypsum, and the gypsum thus produced is recycled to the furnace as a flux.
