In order high efficiently develop and utilize a foreign microfine disseminated iron ore with low cost,both stage grinding stage low intensity magnetic separation process (Process 1)and stage grinding stage low intensity magnetic separation -iron concentrate obtained by magnetic column in ad-vance -middlings regrinding -two stage low intensity magnetic cleaning separation process(Process 2)is conducted.Results indicated that:iron concentrate with iron grade of 68.64% and recovery of 70.17%can be obtained through Process 1;iron concentrate with iron grade of 68.19% and recovery of 70.28%can be obtained through Process 2;By comparison,Process 2 is more efficient and use less energy.
