high-intensity magnetic separation of limonite iron ores vm . - HindawiHIGH-INTENSITY MAGNETIC SEPARATION OF LIMONITE IRON. ORES. V.M. MALIY AND I.P. BOGDANOVA. Mekhanobrchermet Institute, Krivoy Rog 324087, Ukraine. (Received March 10, 1992). Abstract Results ofinvestigation into the development of HIMS technology for separation of weakly magnetic finely.limonite ore magnetic concentration,Magnetic separation of hematite and limonite fines as hydrophobic .The experimental results have shown that the FMS process is effective to recover hematite and limonite fines at a middle magnetic field intensity, greatly increased the separation efficiency, compared with the conventional magnetic separation at the same conditions. By applying the process to the fine hematite ore.Recovering limonite from Australia iron ores by flocculation-high .Successful recovery of limonite from iron fines was achieved by using flocculation-high intensity magnetic separation (FIMS) and adding hydrolyzed and causticized flocculants according to the.
