Gypsum and anhydrite are the hydrated and anhydrous forms of calcium sulphate, which occur in nature as evaporate deposits in the form of nodular masses or beds up to a few metres thick. Gypsum is formed by the hydration of anhydrite at or near surface, but usually passes into anhydrite below 40 to 50 metres.

The amount of added gypsum was converted into the S/Sn ratio that can be seen on the secondary x-axis in Fig. 2. The S/Sn ratio is used as a parameter to observe the availability of sulfur for tin fuming. The S/Sn ratio is the ratio of mole sulfur in gyp- sum and mole tin in slag. The minimum S/Sn ratio is equal to one.
