摘要：

Gravimetric, chemical, and mineralogical analyses of a gold-bearing gravity concentrate have been performed. Intensivecyanidation process of the concentrate was carried out in the presence of an organic reagent, while the concentration of sodium cyanide was changed in a drum-type reactor. The use of a reagent activator increased the gold extraction, reduced the time of the reaction, and reduced the leaching losses of gold in to tailings, even when using low concentrations of sodium cyanide.
