iron ore tailings recovery

A new approach for recovering iron from iron ore tailings ...

2020-2-1  Iron ore tailings, which are important secondary resources, have outstanding latent application value in iron recovery. In this study, a pilot-scale experiment on the iron recovery from iron ore tailings was investigated using innovative technology of pre-concentration and suspension magnetization roasting (SMR), followed by magnetic separation and flotation.

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, representing 35% of the run of mine. Millions of tons of useful minerals are discarded every year into tailings, incurring operation costs, raising production losses and environmental impact. In addition to the disposal of 300 t/h of this material, millions of tons are already stored ...

Recovery of Ultra-Fine Iron Ore from Iron Ore Tailings ...

2017-9-14  Findings show that only at Tilden Iron ore mines, selective flocculation has been commercially used after reverse flotation process . Very few attempts have been taken to establish the selective flocculation process for real iron ore tailings in the laboratory scale [10, 14, 16,17,18,19]. The commercial application of this process is very limited.
