Abstract

Abstract

In order to recovery iron minerals from a flotation tailings in Anshan process mineralogy of flotation tailings was studied which includes chemical multielement analysis, X-ray diffraction analysis and size analysis in Anshan concentration plant. The results indicate that the grade of Fe in tailings of flotation was 19.51%; The iron minerals in the tailings are mainly hematite(or limonite) and magnetite; The gangue minerals is amounts of quartz; The hazardous Substances(S or P)are no many in the tailings. The appropriate process flowsheet(spiral, magnetic separation and reverse floatation methods) had been carried out for recover the iron minerals contained in the iron ore floatation tailing of Anshan concentration plant according to scientific test's investigation, and following results had been achieved: Fe grade, yield and recovery of the ultimate concentrate were 63.50%, 15.99% and 52.07% respectively. The experimental results provided technical support for iron recovery from an iron tailings resource in Anshan.
