The
Centre has developed flow sheets for beneficiation of various ferrous,
non-ferrous and industrial minerals such as graphite, limestone, clay,
magnesite, barite, silica sand ,fluorspar etc. and transferred the
technology to the user industries.
One of the major accomplishments of the Centre has been the
development of Column Flotation technology for Indian Mineral Industry
towards processing of various ores and minerals.
The NML column has been field tested at major mineral industries like
M/s Gujarat Mineral Development Corporation Ltd., Ahmedabad
(fluorspar)
M/s Kudremukh Iron Ore Co. Ltd., Kudremukh (iron ore)
M/s Bharat Gold Mines Ltd., KGF (gold ore)
M/s Hindustan Copper Ltd., Malanjkhand (copper ore)
M/s Hindustan Zinc Ltd., Udaipur (Pb-Zn ores)
M/s Indian Rare Earths Ltd., Chatrapur (sillimanite)
M/s Fomento, Goa (iron ore)
For the first time in the country, the Centre has developed and
installed an indigenous fully microprocessor based automated
laboratory column (75mm dia.) for National Mineral Development
Corporation (NMDC) R&D Centre, Hyderabad.
For educational and research purpose a laboratory flotation column (75
mm dia.) was supplied to Dept. of Mining Engng., Golden Valley
Institution of Technology, KGF
Recently, the Centre has developed an effluent treatment system based
on electro-flotation technique. The system was tested both on
laboratory and pilot scale for the treatment of tannery effluents in
the local tanneries of Chennai. The system totally removes the
suspended solids and substantially reduces the COD and BOD loads of
the effluent.
