Detoxification of Cyanide in Gold Processing Wastewater by Hydrogen Peroxide
Utilizing cyanide compounds in mining and chemical industry is one of the most important environmental issues due to the acute toxic properties of many cyanide compounds to humans and aquatic life. Cyanide tends to react readily with most other chemical elements, producing a wide variety of toxic, cyanide related compounds. This research was aimed at investigating a feasible and economical tech...
متن کاملIntensification Behavior of Mercury Ions on Gold Cyanide Leaching
Cyanidation is the main method used to extract gold from gold raw materials; however, a serious problem with this method is the low leaching rate. In order to improve gold leaching, the intensification behavior of mercury ions on gold cyanide leaching, for two types of materials, sulphide gold concentrate and oxide gold ore, was investigated. The results showed that mercury ions, with only a 10...
متن کاملOre mineralogy and fluid inclusions constraints on genesis of the Muteh gold deposit (western Iran)
The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...
متن کاملEffect of Mechanical Activation on the Kinetics of Ammoniacal Thiosulfate Leaching of a Refractory Oxide Gold Ore
The effect of mechanical activation on the kinetics of ammoniacal thiosulfate leaching of a refractory oxide gold ore containing 2.8 ppm Au was investigated. The gold extraction of 99.81% was achieved by 16 h leaching of a sample mechanically activated for 60 minutes. The gold extraction observed for a similar reference sample without mechanical activation was only 55%. Studies revealed that le...
