• Completed several industry-sponsored projects on ‘Evaluation of reagents for flotation’. Laboratory flotation studies were carried out for various minerals, namely iron ores, graphite ore, limestone, barite, marble, and coal etc. The performance of newly developed reagents on these minerals was evaluated.• Significantly contributed as an active project member to one of the industry-sponsored projects pertaining to the liberation and beneficiation of low-grade limestone. Also involved in the development of process flow sheets by laboratory Denver cell and column flotation techniques and project report preparation.• Involved as an active member in a collaborative project involving studies on the beneficiation of coal fines by column flotation.• Visited Jamadoba Coal Preparation Plant, Tata Steel, Jamadoba, during the installation and commissioning of a 0.5-meter-dia. pilot-scale column for coal beneficiation studies as a project member. We also carried out various process parameter optimization studies on coal beneficiation pilot plant trials at the site.• Involved in the demonstration of the beneficiation process of marble slurry using a 75-mm-dia. laboratory-scale flotation column for industrial clients, namely, M/s Imerys Mineral India (P) Ltd.
