dec 13, 2017 the present investigation examines the viability of dolochar, a sponge iron industry waste material, as a reductant in the reduction roasting of iron ore slimes, which are another waste generated by iron ore beneficiation plants. under statistically determined optimum conditions, which include a temperature of 900c, a reductant-to-feed mass ratio of 0.35, and a reduction time of 3045
jul 31, 2013 pollution from the sponge iron industries is the core reason why communities rise in arms against this industry. 25 26. various cse reports of 2008 inform us 1. in odisha, women from the bonai vana suraksha committee marched up to the district collector with samples of soil, water and grain to protest against sponge iron plants. 2.
(2) processes in which the iron is reduced to the f errous state and chemically leached from the ore and (3) processes in which selective chlorinat ion is used to remove the iron. 5 kerr-mcgee uses the benelit e cyclic process, in which hydrochloric acid is used to leach iron from reduce d ilmenite.
sep 29, 2019 such coal-based sponge iron making from iron ore is popular both in india and china. however, in the world, almost 80 of sponge iron is being produced by the gas-based dr process. both the gas and coal based dri technology are gaining importance due to comparatively less investment cost, flexibility in using raw materials like cheap iron ore
the production process for the sponge iron is as given below the concentrate from the beneficiation plant is used for producing high-grade iron ore pellets. we use a grate kiln technology for production of pellets. using spiral concentrator and magnetic separators we are using low-grade iron ore fines for

sponge iron through dri route 1 x 200 tpd 60,000 to the beneficiation plant. the conveyors will be provided with hoods in order to consists of sponge iron lumps, sponge iron fines and char. magnetic and non-magnetic material will be separated through magnetic separators and stored in separate bins.
sponge iron and even with the best type of magnetic separators. it is virtually impossible to separate out 100 percent of the same from the magnetic sponge iron. non-magnetic/char which is extraneous gangue, is an undesirable part of the sponge iron and hence
sponge iron produced by this plant is of high grade which contains 80 fe, 12 feo and 8 gangue material. after separation of sponge iron in the magnetic screen/pulley, the remains are collected as char. char has good amount of fixed carbon (28 - 35) and moderate gcv (2720 - 2780 kcal/kg).
obtained sponge iron powder with iron grade in range of reduced ore and the residual char were discharged and cooled in a container in nitrogen atmosphere, followed by dry magnetic separation (0.15 t of magnetic field intensity). optimum metallization agrees with the best beneficiation of iron at 1 050c. it is acknowledged that the

to convert the rotary kiln-based sponge iron plant into a pig iron plant, magma smelter is installed in place of the rotary cooler, and all other existing infrastructures are utilized. a 100 tpd sponge iron plant can make 1,08,000 tons of pig iron per year a 200 tpd plant can make 1,72,000 tons of pig iron per year and a 350 tpd plant can make
mar 03, 2017 to preserve the iron ore, secondary sources like ore fines, mill scale, slime and low grade iron ore (after beneficiation) can be utilized. these shall not only improve the reserves position, to the tune of about 1015, by extracting metal is of vital concern
