Globally, tailing impoundment failures frequently occur, making safely held hazardous materials mobile. The pore water within the tailings can have (near-) neutral pH due to acid neutralization before tailings disposal, leading to the generation of neutral mine drainage (NMD) as it leaks from the impoundment. The biogeochemical evolution of key …

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 …
