Recovery of iron from vanadium tailings with coal-based

A technique with coal-based direct reduction followed by magnetic separation is presented in this study for recovering and reusing iron otherwise wasted in vanadium tailings. Process parameters such as usage of additives, tailings/reductant/additives ratio, reduction temperature and time, as well as particle size were experimentally determined.

Iron recovery from zinc mine tailings by magnetic

Considering the whole process, magnetic separation and carbothermal reduction, the recovery of Fe from the zinc mine tailings was 67%. Therefore, the process route suggested in this study will not only reduce tailings disposal and consequently the risk of environmental accidents, but it will also provide profitable raw material for the steel

Recovery of iron from cyanide tailings with reduction

In this paper, recovery of iron from cyanide tailings was studied with reduction roasting-water leaching process followed by magnetic separation. After analysis of chemical composition and crystalline phase, the effects of different parameters on recovery of iron were chiefly introduced.

Efficient iron recovery from iron tailings using advanced

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.

Recycling of iron and titanium resources from early

Geochemical characterization of the tailings was first conducted, followed by the iron recovery and titanium recovery. Iron recovery was mainly achieved through a series of magnetic separation, and titanium recovery was on the combination of magnetic pre-concentration and flotation separation.

Magnetic Separation to Recover Iron Minerals from

A joint process of flotation and magnetic separation was proposed to process the ore. This paper introduces the test results of flotation tailings by a wet drum separator. Results show that iron concentrate assaying 60.21-68.12% Fe at a recovery of 71.9-75.32% can be obtained, when the flotation tailings assays 33.91%Fe.

[PDF] The Challenge to Scavenge IRON from Tailings

Tailings recovery has been a constant challenge for most engineers. Along more than five years, GAUSTEC joined major players in the mining Industry to scavenge Iron from tailings produced by flotation making use of WHIMS (Wet High Intensity Magnetic Separation). In the early 1980s, in USA, the US 4,192,738 patent was granted with promising results.
