A sample of tailings from a local, low grade (less than 2g/t) tailings dump was investigated for gold recovery. The tailings were very fine, with 90 per cent passing 30µm and almost 60 per cent passing 10µm. Tabling the coarse product from classification using a cyclone proved unsuccessful, with low recoveries being obtained due to...
gold extraction from tailings without cyanide. Tailings . Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.
PDF | It is estimated that the tailings dam of the Mouteh Gold Mine, in Iran, contains more than 770 kg of gold. Microscopic analysis reveals that sulphide minerals and active carbon are the main ...
Pyrite has long been used as a source of sulphur, and its recovery as a byproduct from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a ...

Tailings are created as mined ore is processed into particles of fine sand through crushing, grinding and milling. Mined ore is moved to the milling circuit where the rock is reduced into sand and silt sized particles and then mixed with water and moved as slurry through the gold, silver and copper recovery .
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 to

Jan 23, 2015· Abstract. The authors study potential utilization of oil tailings of a leadzinc processing plant. Conversion of sulfides into marketable selective concentrates is carried out in two stages: sulfide product is extracted from tailings, first, and processed, second, jointly with current ore material, using the accepted technology, or separately, by jet flotation.
Jun 14, 2014· A client approached hrltesting to investigate options for precious metal recovery from a gold tailings dam project. The project examined options for reprocessing the tailings material in the existing operational site plant. The goals of the project were threefold: Investigate and optimise gold and silver recoveries by cyanide leaching
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
