One speciality is evaporite gypsum, which is formed during the evaporation of seawater for the production of salts. In 2019, a total of around 435 Mta synthetic gypsum was produced worldwide (Fig. 7). Of this quantity, 136.8 Mta or 31.4 % were used in industry. Of the 176 Mta FGD gypsum produced, 72.8 % were used worldwide.
