Mining production provides basic material and energy guarantee for mankind (China Geological Survey 2019).Like any mining activity, mining production produces a large amount of solid waste, such as tailings and waste rock (Simo et al. 2021).These wastes are stored in tailing disposal facilities (TDF) for treatment and remediation after the end of …

Tailing are different from overburden, waste rock or other substances that cover ore or ore body and are replaced without treatment during mining. The tailing processing methods are varied by minerals, beneficiation methods, particle size, etc. Tailing can be divided into the following types: hand-picking tailing, gravity separation tailing ...
