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 …

Multi-stage crushing facilitates maximum separation of the battery components in the subsequent processes. Moreover, fine crushing avoids the particles from the current collector attaching to the black mass (Diekmann et al., 2017). 3.2.1. Dry crushing. Dry crushing is the direct crushing of spent LIBs without the presence of water.

Gravity separation is used to separate valuable minerals from gangue based on the difference in their specific weight or density. This technique relies on the principle that denser particles will settle faster under the influence of gravity, allowing for effective separation. Here is a step-by-step explanation of gravity separation in mining ...

Solid waste will be screened two categories including waste over than 50mm and less than 50mm. Waste with size less than 50mm is mainly organic. Metal materials in this organic is sorted by suspended magnetic separator. Waste with size over than 50mm is put into magnetic separator to sort out iron materials (iron beverage cans and packing pot).

In this study, a method for upgrading iron from the waste copper slag discharged as an industrial waste has been developed. The process first crushes the waste copper slag between 150 and 203 μm, followed by reduction reaction at 1250 °C for 1.5 h. And then, the resulting material is again crushed to 75–104 μm, followed by dry magnetic ...
