Abstract: In order to improve recovery of an iron ore in Xinjiang,based on system research of raw ore properties,at grinding fineness is 30% -0.074 mm,with one roughing one scavenging low intensity magnetic separation process,iron concentrate with iron grade of 68.32%,iron recovery of 83.12%,tailings of magnetic iron content is 0.42%,magnetic iron recovery was 97.15%. By optimizing conditions test,provides the technical guidance for on-site production.
