    2017-12-12 · The mineral extraction processes usually incorporate a foam flotation stage in which the gangue is separated from the ore by the addition of flocculants to water. The flotation has become the most competitive extraction method, since it provides a good ore-gangueseparation, with very profitable energy cost. However, this process increases water consumption significantly, generating a significant amount of tailings Iron Tailings Re-Processing Technology, A New Weapon for,2020-11-19 · Therewith, it is a good consideration to use the combined separation methods for the iron tailings re-processing. For the combined gravity-magnetic-flotation separation to recover the iron in the iron tailings, it usually takes the gravity separation as the pre-enrichment to improve the grade of minerals entering magnetic separation.
