Kimberlite tailings for the presence of total arsenic. The arsenic contamination of groundwater was found to be location specific in North 24-Parganas district. The maximum arsenic concentration at certain places was found to be many folds more than the WHO recommended limits. The treatment of arsenic contaminated water samples with kimberlite tailings showed 90-94% removal in 12 hours. The present study can be used as a basis for designing and developing filter columns, which can be attached to the tube wells for low cost and effective removal of arsenic. Kimberlite tailings Kimberlite tailings are waste materials left after the recovery of diamond
Kimberlite tailings at higher temperature to obtain Zeolite-A. The product is useful as builder in detergent formulation. With a view to assessing the potential use of kimberlite tailings in road works, the Central Road Research Institute engaged in a detailed laboratory study. Kimberlite tailings were characterized to determine their physical engineering properties. Results indicate that kimberlite tailings are a marginal material and possess adequate strength for use in the construction of rural roads. The feasibility of utilizing this material for the construction of various layers of road pavement by adopting stabilization techniques was investigated. A study was also undertaken to assess the
