Abstract

Abstract: Using magnetic flotation column instead of flotation machine on clearting low intensity magnetic intermediate concentrate,the experimental study of impurities reduction of iron concentrate were carried out.Specific discussed collector MH and iron minerals inhibitor starch dosage,the additional pulsed magnetic field strength and the equipment processing.The test results showed that:In the best technology conditions,the iron grade is 69.85%,the iron recovery is 99.05%.

Key words: Magnetite, Pulsed magnetic field, Semi-industrial test
