Recovery Of Gold And Silver Sulphide Ores

The ores distributed in goldsulphide-type deposits were conditionally classified into two types 1 low-sulphide vein-disseminated ores that are difficult to dress containing invisible native gold and increased silver content and 2 low-sulphidequartz veins with free native gold.

  • The Cesl Gold Process Teckm

    Cesl gold process.Gold and silver value in copper concentrates gold and silver occurring in copper sulphide ores generally follow the copper into the flotation concentrate in fairly high yield and, given current precious metal prices, the amount of gold and silver required to be economically significant is quite low.

  • Silver Sulphide What To Do About It Gold Refining

    Handling silver sulphide ag2s is a nightmare,but we have got to do it because silver easily reacts with sulphur.Ag2s is greatly insoluble so all silver compounds can be converted to silver sulphide.Most silver ores are ag2s,called acanthite.

  • 17 Flotation Of Gold Ores

    During flotation of gold-bearing massive sulphide ores, the emphasis is generally placed on the production of base metal concentrates and gold recovery becomes a secondary consideration.In some cases, where significant quantities of gold are contained in base metal ores, the gold is floated from the base metal tailings.

  • Recovery Of Gold From Ore Indrive Project

    Recovery of gold in pyritic sulfide ores mine engineer.Recovery of gold in sulfide ores has fallen into several egories.First is froth flotation, and second is cyanidation of the ores.Using cyanide to recover gold from sulfide ores generally results in 30 to 35 recovery, and the best i have heard of is around 50 recovery.

  • Increased Recovery From Preg Robbing Gold Ore At

    Preg-robbing gold ores, yielding very low recoveries from traditional cil methods.Gold recovery from the cyclone underflow was targeted to recover as much gold as possible in the absence of the fine preg-robbing carbon.Gold is recovered by intensive cyanidation and tabling of a gold concentrate produced by gravity from the cyclone underflow.

  • Procedure For Processing Sulphide Gold Containing

    Substance invention relates to method of processing sulphide gold containing arsenic concentrates.Method involves mixing, annealing, treatment of gas phase and cinder leaching with extraction of gold, silver, nonferrous and rare metals.Batch is prepared by mixing concentrate with ammonium chloride in weight ratio of 10.
