*7.2.2.6. Minerals*

Free and metal‐complexed cyanides are adsorbed by solid wastes, soils and ores containing minerals such as bauxite [AlO.OH/Al(OH)3], ilmenite (FeTiO3), haematite (Fe2O3) and pyrite (FeS2). Mineral groups such as zeolites, clays and feldspars are also effective adsorbents [64, 65].
