Dr .D.M.R. Sekhar is a graduate in chemical engineering and a post
graduate in mineral process engineering from Andhra University. He was awarded
Ph.D degree by Andhra University for his thesis on “separation of sulfide
minerals from complex ores”. He published 64 technical papers of which 25 are
in peer reviewed journals. He is a recipient of “National Mineral Award” for
the year 1997 from the Government of India, “Mineral Beneficiation Award” for
the year 2002 from the Indian Institute of Mineral Engineers and “Mining
Engineering Design Award” for the year 2004 from the Institution of Engineers
(India). Dr. Sekhar served M/s Hindustan Zinc Ltd (1979- 83). M/s Rajasthan
State Mineral Development Corporation Ltd (1983-1995) and M/s Rajasthan State

Dr. Sekhar designed an unconventional grinding circuit for Phosphate Ore
Beneficiation Plant at Jhamarkotra, India that involved a roller press
operating in tandem with a wet grinding ball mill which proved to be highly
energy efficient. Dr. Sekhar along with Prof. NC Aery carried out the
pioneering experiments on Phosphate Rich Organic Manure [PROM] which proved to
be more efficient than Di Ammonium Phosphate the well known chemical phosphatic
fertilizer.
