Abstract

Water saturated with CO2 at about 25°C was percolated through mixed beds of limestone or marble fragments and montmorillonite, “illite” and kaolinite in polyethylene tubes for six and fortyfive complete runs. The leachates were analysed for SiO2, A12O3 and Fe2O3, but only SiO2 was found. The minerals lost SiO2 in this order: montmorillonite > kaolinite > “illite”. The differential removal of SiO2 during the short period of these experiments suggests a mechanism for the accumulation of bauxite deposits associated with limestones.
