Development and industrial adaptation of a resource-saving technology for magnetite–hematite concentrate production from manmade iron-ore feedstock

The studies aimed at development of a resource-saving processing technology for Zaimandrovsky ore concentration tailings put into storage. Based on the revealed patterns of material composition of tailings samples, it is expedient to perform preliminary classification of the tailings by the size grade of 0.63 mm, which ensures the increase in the mass fraction of iron and the reduction in the aggregation of valuable minerals in the original feed of separation at minor ore loss with screen overflow. Layouts of the gravity preparation equipment for the proposed process flowsheet are selected and validated. The flowsheet includes three stages of spiral separation which ensures stable production of iron ore concentrate from both commercial-grade and low-grade manmade initial raw material. The prospects of weak-field magnetic separation for the magnetite concentrate production are assessed. As a result of the accomplished research, two versions of a resource-saving technology for processing of tailings are proposed: gravity separation and magnetic gravity separation. These technologies enabled production of iron ore concentrates with the iron contents of 65% and 62% at the recovery of 59% and 62%, respectively.

Keywords: manmade tailings, tailings put in storage, ferruginous quartzite, hematite, magnetite, gravity separation, spiral separation, magnetic separation, screening, iron ore concentrate.
