BENEFICIATION OF LOW/OFF GRADE IRON ORE: A REVIEW
· Due to gradual depletion of highgrade iron ores (6577 % of Fe) has develop the maximum possibility of utilization of lowgrade iron ore. But this required much more economical support. Many literature highlight that upgrading the fines ores utilizing this fraction in the sinter feed up to 40% by microballing of the sinter prior to sintering (Shrivastava and Prasad 2001). The simple way .
DRY BENEFICIATION OF LOWGRADE IRON ORE FINES USING .
results are presented on the beneficiation of lowgrade Fe ore fines using STET belt separation process. Benchscale testing demonstrated the capability of the STET technology to simultaneously recover Fe and reject 5 E 1 6 from itabirite ore with a D50 of 60µm and ultrafine Fe ore tailings with a D50 of 20µm. The STET technology is presented as an alternative to beneficiate Fe ore fines ...
