Kimberlite tailings solution, which is subsequently neutralized with mineral acid to polymerize silica as insoluble precipitates. The products is useful in rubber, paints as abrasive etc. The experiments were conducted to investigate the sorption of arsenic from the groundwater onto kimberlite tailings in two phases - batch studies and column studies. In batch studies, the effects of different factors such as pH, adsorbent dose and adsorbent size on the performance of kimberlite tailings were investigated. Adsorption kinetics and equilibrium isotherm studies were also carried out. The adsorption capacity of kimberlite tailings was calculated as 0.25 mg/g of adsorbent. In column studies, the
