Typically, tailings, as solid waste, are discharged into rivers or are contained in tailing dams. Antimony ore tailings contain Sb, As, Hg, and other heavy metals [1-4] that are highly toxic [5-7]. Previous reports have shown that the majority of heavy metals pollution appears to originate from mining and industry, because

What are tAILingS Put simply, tailings are ground up rock minus the gold. Rocks mined from underground which contain gold are called ore. Processing involves crushing the ore into sand to liberate and recover the gold. What's left over is called tailings. Approximately 95% of the tailings are generated from gravity separation methods, which are []

Antimony can be considered both a critical metal and an environmental hazard, with a toxicity similar to arsenic. It is concentrated in stibnite deposits, but also present in polymetallic and precious metal ores, frequently accompanied by arsenic. We have studied the mineralogical controls on the mobility of antimony in three types of mine waste: stibnite tailings from an
