Apr 01 2019 at 15000 gauss a 2 stage magnetic separation increases iron recovery from 60 to about 70 in the 2nd stage but no increase in fe 2 o 3 in the red mud is seen this confirms the fact that fe 2 o 3 present in hematite form does not get magnetized even with the increase in separation stages
Rougher tests of magnetic separation produced concentrates with iron content of about 582 fe the tailing of rougher stage was then scavenged using higher magnetic intensity further the rough and scavenged concentrates were mixed and fed into a cleaner stage with low magnetic intensity
