Kimberlite tailings suitability of this material for use in bituminous mixes. The laboratory studies indicate that kimberlite tailings can be used in subbase and base course layers in a road pavement. They can also be used in bituminous macadam as the base course and in premix carpet as a wearing course. A 1-km-long road was constructed near the diamond mine using kimberlite tailings, and its performance was monitored during a period of 1 full year. The road's performance was found to be satisfactory. However, since kimberlite is one of the fastest weathering rocks found on the surface of the Earth it is
Kimberlite tailings performance of fixed-bed kimberlite tailings was studied and the adsorption capacity was found to be 0.27 mg/g of adsorbent. Film diffusion was found to be the rate-limiting factor for the removal of arsenic by kimberlite tailings. Adsorption of arsenic was found to be pH dependent and higher removal efficiencies were observed near neutral pH range. The arsenic uptake increased with increase in adsorbent dose. Spent kimberlite tailings could be regenerated with dilute NaOH. The proposed treatment methodology was applied to the groundwater samples collected from various places of North 24-Parganas district situated in West Bengal, India. The samples were analyzed
