DESCRIPTION :

Dr. Chinmaya Kumar Sarangi received B. Tech. degree in Metallurgical and Materials Engineering from National Institute of Technology (NIT) Rourkela, India. He  obtained M. Tech. and Ph.D in Metallurgical and Materials Engineering from Indian Institute of Technology (IIT) Kharagpur India. He has been working for the last twelve years in the Hydro and Electrometallurgy Department at CSIR-Institute of Minerals and Materials Technology (CSIR-IMMT), Bhubaneswar, India. Before joining CSIR-IMMT, he was working as a scientific officer in Bhabha Atomic Research Center (BARC), Mumbai, India. He has work experience on the process development for extraction of metal values ​​from various low grade ores, wastes and secondary resources. He has worked on several projects which involve processing of complex resources for extraction of critical metals like tellurium from anode slimes, nickel from copper refinery effluent, cobalt from  scrap/sludge, tungsten from scrap and tailings concentrate, recovering alumina from fly ash, etc. He has developed an electrolytic-membrane technology for the recovery of value added products like alkali and acid from sodium sulphate or ammonium sulphate bearing industrial effluents. Earlier he worked on electrolytic acid killing of high level liquid waste raffinate solution and recovery of Pd using ionic liquids. His work is widely useful for non-ferrous metal industries in developing suitable technologies to extract desirable metals from their respective primary and secondary resources. The processes and flowsheets developed for the recovery of valuable metals are useful for the commercial plants dealing with metal production. It is also well supportive for the entrepreneurs, who are intent to set-up small scale industries with low capital investment. He has published patents and SCI publications in several International Journals.
