Life cycle assessment as a design consideration for process development for value recovery from gold mine tailings - ScienceDirect

Highlights ? Cyanide and thiosulphate flowsheets for Au recovery from tailings were simulated. ? HSC chemistry and Gabi? were used to develop an LCA for gold tailings. ? Lixiviants are demonstrated to have highest impact on gold recovery flowsheets. ? LCA is used to determine the environmental impacts of unit operations in mining. Abstract

Cyanide and removal options from effluents in gold mining and metallurgical processes - ScienceDirect

The common cyanide treatment methods include natural degradation in tailings ponds and chemical and biological degradation processes. Chemical processes may consist of alkaline chloride oxidation (alkaline chlorination), hydrogen peroxide oxidation, Inco SO 2 /Air oxidation, Hemlo/Golden Giant (copper and iron sulphate) precipitation and Acidification¨CVolatilization¨CRegeneration (AVR).

heavy metal pollution from gold mines: environmental effects and bacterial strategies for resistance - pmc - national center for biotechnology

Heavy Metal Pollution from Gold Mines: Environmental Effects and Bacterial Strategies for Resistance - PMC - National Center for Biotechnology

Environmental pollution from gold mines is associated mainly with the release of harmful elements from the tailings and other mine wastes. The infiltration of water through sulphide- containing tailings piles and ponds, surface and underground workings, waste and development rock leads to leaching of large volumes of metals like Zn 2+ , Ni 2+ , Pb 2+ , AS 2+ , Cu 2+ and sulphate ions into

As one of the inorganic pollutants with the highest concentration in the waste water of gold tailings using biohydrometallurgy, thiocyanate (SCN?) was effectively degraded in this research adopting a two-stage activated sludge biological treatment, and the corresponding degradation pathway and microbial community characteristics in this process were also studied. The results showed that SCN
