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 different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then, slag-tailing concrete composite admixtures …

Essentially, the concentrator is a centrifuge that combines enhanced gravitational force with a water injection process to create a fluidized concentration surface into which fine gold grains (due to their high specific gravity) can penetrate and become trapped. The original device operated at 60 G forces, and 30 years later extensive …
