Abstract

Magnetic separation is a common method for processing low-grade iron ore, removing naturally occurring magnetic iron from nonmagnetic materials, with reduction roasting followed by magnetic separation showing promise for recovering iron values. In this study, hematite ore was processed by crushing, grinding, sieving, and dividing the samples into two groups. The first group consisted of samples for reduction (roasting), where 50g of the ore were mixed with coal in proportions of 0.25 inside a crucible, placed inside an electrical furnace at a temperature of 700°C for 60 min, and then separated magnetically. The second group consisted of samples that were magnetically separated. As the results of the first group showed, the iron grade increased from 30.36% Fe to 60.12% Fe, and the recovery reached 84.31%, with a noticeable decrease in the percentage of impurities. As for the second group, the iron grade increased from 30.36% Fe to 45.08% Fe, and the recovery was 75.22%.  From the results, noticed that the results of the first group were higher than those of the second group. Therefore, it was concluded that magnetic reduction (roasting) increased the magnetic susceptibility of hematite and thus increased the grade and recovery, so the final concentrate can be used for the processes necessary to create iron and steel suitable for the necessary industrial requirements.
