Traditionally, gold mining has depended on harsh chemicals such as cyanide and mercury to extract gold from ore. This has left our planet with a legacy of toxic waste which is harmful to health and the environment. For over 50 years, the industry and leading research institutions have been trying to find such an alternative without much success.

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 were prepared from high-silica residues.

Iron, a common constituent in ores and tailings, is problematic due to its high extractability by many of the aforementioned conventional reagents, notably DEHPA, Cyanex 923 and Cyanex 272. Tailoring more selective extraction processes is, therefore, very important in the extractive metallurgy of REEs, especially for low-grade feeds.

Mineral tailings from two copper mines were bioleached under different conditions. • Greatest copper extraction was achieved at extremely low pH, at 45 °C and under oxidative/reductive conditions.. Copper present in tailings PLS was selectively precipitated as CuS by biogenic H 2 S.. Microbial communities were dominated by Sb. thermosulfidooxidans and …
Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts, another strategy is to produce thickened tailings, which are pressed or have chemicals added to remove excess water ...
The steel industry plays an important role in developing countries such as China. Despite its benefits, large quantities of iron ore tailings (IOTs) are generated as byproducts during the processing of steel (Yao et al. 2015).In China, the total accumulation of IOTs has exceeded 7.5 billion tons (Chen et al. 2012), and the annual increment is about 500 million tons (Tang et al. 2019a).
