Zeolite Production
A range of Zeolite minerals may be produced by reacting silica, alumina and cations under hydrothermal conditions (pH 10-14, > 100°C), and the abundant aluminosilicate glass component in FA provides a potential raw material for Zeolite synthesis. Zeolites are used as control release fertilisers, soil conditioners, ion exchange media, and also as detergent builders, pesticide carriers, and animal dietary supplements. Although natural Zeolites are also available, synthetic Zeolites, including materials made from FA, may be tailored more specifically to meet particular market requirements.
