native gold from goldbearing ores. It has been known for more than a century that alkaline solutions of alkalimetal cyanides e.g., NaCN, KCN dissolve gold under aerated conditions. The dissolution of metallic gold is due to the strong complexing capabilities of cyanide anions combined with the oxidizing properties of the dissolved molecularOnline Consulting

gold from certain refractory ores. A mechanism is proposed which involves the dissociation and precipitation of these metalcyanide complexes, where the cyanide from the dissociation of the complex is used to leach gold from the ore. The stepwise dissociation of cyanide from coppercyanide complexes can also be used to leach goldOnline Consulting
the ore was performed to distinguish the goldbearing phases present and hence, to characterize its refractory behaviour. The mineralogical characteristics of the ore were also examined to aid the evaluation of the leaching behavior of gold and silver from the ore. 2 Materials and methods 2.1 MaterialsOnline Consulting
The industrial gold recovery becomes more challenging, since high grade ores are becoming rare. Gold producer are forced to use increasingly complex and low grade ores. Especially for refractory and carbonaceous pregrobbing ores cyanide leaching shows an insufficient gold recovery 2. Besides this, also different process residues from gold winning plants and gold containing end of life productsOnline Consulting
There are many nonidealities in gold processing which are becoming increasingly important as simple freemilling oxide ores are depleted. During cyanidation and adsorption onto activated carbon, these effects include competing metalcyanide complexes, pregrobbing and the mineralogy of the ore.Online Consulting

The flotation feed and copper concentrate showed an enhancement in gold extraction due to the activated carbon adsorbing gold that would otherwise have been pregrobbed. However, this mechanism did not explain the behaviour of the pyrite concentrate. For this ore the enhanced extraction was due to a combination of equilibrium and pregrobbing ...Online Consulting
