Recovery of iron from hazardous tailings using fluidized

01/02/2020· Li et al. presented a technique for recycling iron ore tailings via the coal-based magnetization roasting process followed by magnetic separation (MRMS). Using a similar method, rare-earth tailings containing 13.06% Fe could be transformed to an iron ore concentrate assaying 45.00–49.00% Fe with a recovery of 65.00–77.50% [ 10 ].

Recovery of Ultra-Fine Iron Ore from Iron Ore Tailings

14/09/2017· Here the study focuses on the application of selective flocculation process for beneficiation of synthetic mixtures of iron ore and kaolinite as well as iron ore tailings. Results show that it is possible to achieve 65.78(%) of Fe, with 2.65% Al 2 O 3,3.66 SiO 2 (%) in the concentrate using synthetic mixture feed and more than 60% of Fe is obtained from natural iron ore tailings.

Recovery of Iron Ore Tailings byColumn Flotation

The exploration of iron ore in small mining companies results in a large amount of unrecovered fine material, repre- senting 35% of the run of mine. Millions of tons of useful minerals are discarded every year into tailings, incurring op- eration costs, raising production losses and environmental impact. In addition to the disposal of 300 t/h of this material, millions of tons are already

Novel method for iron recovery from hazardous iron ore

In this paper, a novel method to recover iron from iron ore tailing (IOT) was studied. The method was induced with carbothermic reduction, followed by magnetic flocculation separation (MFS) and conventional magnetic separation (CMS). The effects of reduction temperature, as well as the amount of coal and sodium carbonate on iron recovery efficiency, were chiefly introduced according to the

Efficient enrichment of iron concentrate from iron

Iron ore tailings are industrial solid wastes generated from mineral processing. The disposal of iron ore tailings leads to environmental threat and serious security because of their tiny particle size and large storage. In this paper, suspension magnetization roasting and magnetic separation technology were utilized to recover iron tailings. The results showed that iron concentrates with iron
