Abstract: This paper briefly described the nature of a hematite ore and the investigation on its technical conditions for beneficiation from the grinding fineness, the type and dosage of reagent.With reference of the conditioning tests, a closed circuit experiment of one roughing-three cleaning-two scavenging-middle ores back to the feed was carried out.Then, iron concentrate grading at 62.55% with a 71.57% iron recovery of was obtained.
