Transcript of DMR SEKHAR

DMR SEKHARDecember 2010
Brief profile of Dr. DMR Sekhar Dr. DMR Sekhar is a graduate in chemical engineering and a post graduate in mineral process engineering from Andhra University. He was awarded PhD degree by Andhra University for his thesis on “separation of sulfide minerals from complex ores”. He published 67 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 Mines and Minerals Ltd (1995-2007) at various positions and was Group General Manager in M/s RSMML before joining M/s Wharton Overseas FZE, Ajman, UAE as Executive Director. He is currently on deputation with M/s JPMC Plc, Jordan. 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 that reduced power consumption by 15 kWh per ton of ore treated. 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.
