Abstract
The dissolution into water of anhydrite and gypsum was studied at 25°C using a rotating disc of polycrystalline material, and the kinetics were followed with a calcium selective electrode. The dissolution rate of gypsum was transport controlled while that of anhydrite was intermediate between chemical and transport control.Keywords
