Gold mining tailing: Environmental availability of metals,
The gold ore from sulfide minerals is, in general, ore dressed by means of nine stages among which stand out flotation and cyanidation. The residues of these steps, containing potentially toxic elements, such as As, Cd, Cr, Mn, Zn and Pb disposed of tailings dams, which might be a source of environmental contamination if not suitably disposed and/or in cases of accidentsTailings Dams – A Threat to the Environment - Clean Mining,17/03/2021· Tailings and tailings dams are part and parcel of the gold mining industry since time immemorial. Tailings are the waste products from mining after the valuable minerals such as gold and copper have been extracted using mechanical and chemical processes to grind up the ores into fine sand.The dangers of tailing dams on the planet - Clean Mining,25/11/2019· Clean Mining’s gold recovery process eliminates the need for tailing dams and replaces toxic chemicals like cyanide and mercury with a safer, less hazardous and more environmentally-friendly chemical reagent containing thiosulphate.Physico-chemical Characteristics of a Gold Mining Tailings,,The tailings dam stores process effluent from the gold extraction plant.
