Tailings are a by product of a gold mining process thatmon in the late 1800s and early 1900s. Gold bearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold. The remaining sand like substance, known as tailings, was typically dumped into low lying areas or lakes and streams near the mine
The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, Inco SO 2 /air detoxification circuit to convert cyanide to the much less toxic cyanate before waste is discharged to a tailings pond. Typically, this processpressed air through the tailings while adding sodium metabisulfite, which releases SO 2. Lime is used to maintain the pH at around 8.5
The mining process generates two byproducts: Waste Rock: rock that is non mineralised, or mineralised rock which contains insufficient gold to process economically Tailings: the slurry that remains once the gold and silver have been extracted from the crushed ore at the processing plant Waste rock .
