Studies on the characterisation and beneficiation of tensa iron ore fines to develop an iron ore
process flowsheet

To envisage national steel production of 300 million tons In this regard, M/s. JSPL Anugul has approached CSIR-
by 2030, M/s. JSPL, Ltd. put up a 6000 MTPA integrated IMMT to develop a beneficiation process for iron ore fines
steel plant at Anugul, Odisha, India. Presently, the plant to improve the grade of the ore and reduce the alumina
is receiving a part of iron ore used in steelmaking as fines content of the ore. Different process flowsheets have been
from Tensa mines, Odisha. The average composition of developed following physical beneficiation and reduction
iron ore fines is 57% Fe, 9.23% SiO , 4.6% Al O and 3.47% roasting. It is possible to upgrade the ore to 64.5% with a

The representatives of M/s. Vedanta Sesa Goa, Mr. Narvadeshwar Kumar and Mr. Sharath Venkateshlu witnessed the
green pellet preparation, pellet induration in a muffle furnace, pellet induration in pot grate set-up and visited different
facilities of the Mineral Processing Pilot plant.
