DESCRIPTION :
Dr. Swagat S. Rath commenced his research career
in the Department of Chemical Engineering at the Indian Institute of Technology
Kanpur during his Master of Technology program. He subsequently held research
and development positions in industry, serving as Assistant Manager (R&D)
at ACME Telepower Ltd., Gurgaon, and later as R&D Lead at Aster Pvt. Ltd.,
Hyderabad. He also worked in the R&D division of Gharada Chemicals Ltd.
before joining the Council of Scientific and Industrial Research – Institute of
Minerals and Materials Technology (CSIR‑IMMT), Bhubaneswar, as a Scientist in
2011.
At CSIR‑IMMT, Dr. Rath has pursued research in
mineral beneficiation, with emphasis on developing process flowsheets for low‑grade
and complex ores. His work has addressed beneficiation of iron ores, lithium‑bearing
hard rocks, bauxite, manganese ore, chalcopyrite, and potash‑bearing hard
rocks. He has contributed to methodologies for extracting lithium carbonate
from primary Indian resources, applied molecular modeling to the design of
flotation reagents, and advanced reduction roasting and magnetic separation
techniques for low‑grade iron ores using cost‑effective reductants.
Dr. Rath has executed more than twenty projects
sponsored by industry and government organizations. His research has been
disseminated through approximately seventy publications in international peer‑reviewed
journals indexed in the Science Citation Index, which have collectively
received more than three thousand citations. These publications address both
fundamental and applied aspects of mineral processing, flotation chemistry,
computational modeling, and sustainable beneficiation practices
