According to the characteristics of a micro-fine magnetite from Shanxi that a part of magnetite is interbedded interactive disseminating in the micro-fine gangues with a high sulfur content resulting in difficulty for processing,a technological process including rough crashing for raw ore and tailings discarding by magnetic pulley-tailings discarding by magnetic separation-regrinding for the magnetic rough concentrate for desulphurization by flotation-magnetic concentration for flotation tailings was proposed based on the process mineralogy studies. The whole process test can obtain the iron concentrate containing 65.15% of iron and 0.11% of sulfur with 73.10% of iron recovery rate and sulfur concentrate containing 25.12% of sulfur with 30.67% of sulfur recovery rate.
