Minerals | Free Full-Text | Recovering Iron from Iron Ore Tailings …
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 …

The Application of Thickener in Mining Industry
The application of thickener in the mining industry. 1. Dewatering operation of concentrates of red ore minerals such as hematite. For the red ore that is beneficiated by the flotation process, the use of a high-efficiency thickener can obtain a higher underflow concentration and increase the dehydration rate of the concentrate. 2.
