| titleOfInvention | PROCESS FOR EXTRACTING PRECIOUS METALS FROM ORE CONCENTRATES. |
| abstract | Wet chemical process for obtaining gold and silver by direct sulfuric oxidative disintegration of arsenopyrite concentrates (FeAsS2) carbonated with silicate gangue or silicate or pyrtitic gangue, in which arsenic and iron are completely converted into solution and the precious metals are quantitatively enriched in the silicate residue. After decarbonization of the residue, it is possible to obtain gold and silver by cyanide leaching without loss of adsorption. Also described is a wet chemical process for manufacturing concentrates with high gold and silver content. |
