2019-4-15 Abstract: Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at di erent points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then,

2021-2-15 Recycling iron tailings is significant for environmental security and resource recovery, as they contain iron-rich minerals. Given the complex composition of iron minerals and the low grade of iron present in the tailings, innovative suspension roasting-magnetic separation (SRMS) technology was proposed to treat iron tailings that would separate out the iron minerals for recovery.

2020-2-1 A pilot-scale experiment on iron recovery from iron ore tailings using pre-concentration and then SMR followed by magnetic separation and flotation was performed. The iron grade of the iron ore tailings was upgraded from the initial 21.51% to 26.01% by the pre-concentration process of a staged LIMS and two-staged HIMS.
