Water plays a crucial role in mineral beneficiation, and thus dewatering the tailings from mineral processing plants has great importance. This paper discusses the influence of chemical conditions (pH, flocculants, surfactants, and coagulants) on the filtration performance of iron ore tailings.
In iron ore processing plants, different tailing streams are usually transferred to the tailings thickener for partial dewatering and finally transferred to the tailings dam as a single stream. Therefore, the mixing of different tailings streams happens. This way can challenge the process of reprocessing the tailings in the tailings dam since the mixing of …
