al., 2016), and for the conversion of bauxite tailings to highly-crystalline zeolites (Ma et al., 2014). Cyanidation tailings have been used to synthesize nano-iron red oxide pigment (Li et al., 2008). Iron ore tailings have served as secondary resource for the synthesis of iron oxide and ultimately
Mine tailings (MTs) are the materials dumped on a mining site after mineral extraction, containing scattered traces of residual minerals, dug-up soils, and a disturbed ecosystem. Abandoned and untreated MT can pose threats to the surrounding ecosystem due to the presence of various primary and secondary toxic components, such as …

As for the tailings, they either get stored in a …
tailings facilities and their consequence of failure. While not exhaustive, it illustrates the enormous volume of tailings that need to be safely managed. In 2001 Davies reviewed tailings facility failures up to that time and observed that all were predictable in hindsight and could have been prevented during the design and/or operational phase.
1. Introduction. Gold mines are an important component of metal mineral resources and play an important role in the development of the aerospace, electronic communication, medical medicine, precision instruments, jewelry, financial investment, and many other fields (Qi et al., 2021).Currently, gold is derived primarily from mines of …
The majority of the proposed tailings treatment processes rely on technologies that have already been tested and possibly implemented with richer and less complex ores. Thus, these processes can be considered technically feasible for tailings treatment, especially after tailoring the full plant layout to allow more complex …
