Interfacial processing: Exhaustion of high-grade ore and existing resources having complex liberation characteristics leads to fine comminution to achieve mineral liberation. However, the extraction of valuable minerals has been a challenge. Therefore, it requires developing a deep and smart process to recover the mineral values from the ore body. We have exploited the surface potential of a mineral particle to separate from the ore body in a wet and dry process. We have developed a tribo-electrostatic process to recover the carbon values from coal, separating the cenosphere from fly ash and separating carbonate and silicates. A novel froth flotation process has been developed for coal preparation, phosphate, barite, iron ore etc. we also provide a solution to dry coal and mineral concentrate and tailings through technological intervention and innovation.

Green surfactant: The exploitation of natural mineral resources fosters the economic growth of any country. Our country is endowed with ferrous and non-ferrous ores, beach sand minerals bearing rare earth elements (REE), and strategic and precious metal-bearing mineral deposits. In the present scenario, the base and strategic metals are beneficiated by froth flotation and solvent extraction techniques, respectively. Some of the collectors used in the process are toxic/hazardous. Further, the process water generated from mining and metallurgical operations is contaminated with various pollutants which pollute the environment. Therefore, We have screened renewable resources and developed green reagents that are the economical and environmentally more sustainable alternative to the toxic reagents used in flotation. Our green reagents are highly selective to carbonate minerals.

Equipment design: We have developed novel cutting-edge unit operations for fine coal and mineral separation. These unit operations are compact and efficient. We look forwards to their commercialization.
