The process There are two stages in the recovery of gold from surface tailings Surface recovery The retreatment business is high-volume and low-risk Vast quantities of material are processed monthly through the plant in order to recover gold from old mine dumps at a recovery rate that varies depending on the material being treated
Recovery of gold from the Mouteh Gold Mine tailings dam of samples taken was around 200 kg (5–7 kg from each hole) The gold assay of the samples ranged from 0 6 to 2 3 g/t with an average of 0 976 g/t (1 g/t) It was observed that the gold assay increases from the bottom to the top of the holes indicating that the plant used to perform

4-10-2019One of the largest hazards often found in abandoned gold mining tailings is acid mine drainage Due to inefficiencies in the extraction process large volumes of sulphides often end up going into the tailings Over time the sulphides start to oxidize as they're exposed to wind snow and temperature changes creating sulphuric acid
A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury leaving behind the gold This process does not result in gold that is pure but it does eliminate the bulk of the impurities
