| titleOfInvention | AQUEOUS COMPOSITION CONTAINING CYANIDE, INCLUDING AT LEAST ONE NON-IONIC SURFACTANT AGENT FOR THE EXTRACTION OF METALS FROM MATERIALS CONTAINING THEM |
| abstract | WHERE THE NON-IONIC SURFACTANT AGENT, AT A CONCENTRATION OF 0.01 TO 0.2% BY WEIGHT IN AN AQUEOUS SOLUTION ADJUSTED TO A pH OF 9.8 TO 10.2 WITH NaOH, AT 23 ° C LEADS TO A REDUCTION IN THE ANGLE OF CONTACT IN THE GLASS AFTER 1s BETWEEN 10 ° AND 40 °. SAID AGENT IS SELECTED FROM ALCOHOL ALCOXYLATES, ALKYLPHENOL ALCOXYLATES, ALKYLPOLYGLUCOSIDES, BLOCK COPOLYMERS OF ETHYLENE OXIDE, PROPYLENE OXIDE AND / OR BUTYLENE OXIDE, POLYLERIDESYL ALCOHOL DERIVATIVE, BUTYLENE POLYMERIDES / AUTHYL AXYL DYLBERYHYL DYNOLY DERIVATES AMONG OTHERS. THE COMPOSITION ADDITIONALLY INCLUDES AT LEAST ONE CATIONIC SURFACE ACTIVE AGENT AND / OR AT LEAST ONE ANIONIC SURFACE ACTIVE AGENT. THE COMPOSITION IS CONTACTED WITH MATERIALS CONTAINING OPTIONALLY GROUND METALS, IN THE PRESENCE OF AN OXIDIZING AGENT, IN ORDER TO OBTAIN A MOTHER LIQUOR ENRICHED WITH METAL CYANIDE COMPLEXES, THE METAL COMPLEX BEING SEPARATED AND THE METAL COMPLEX REDUCED FROM THE METAL. THE METAL IS GOLD, SILVER AND / OR PLATINUM, AND THE MATERIALS CONTAINING GOLD ARE SELECTED FROM QUARTZ CONTAINING GOLD, PYRITES CONTAINING GOLD, SILVANITE, NAGIAGITE AND CALVAITE; AND THOSE CONTAINING SILVER ARE SELECTED FROM SOUR SILVER, STROMEYERITE AND DOUBLE SILVER SULFIDE WITH ARSENIC SULFIDE AND ANTIMONIUM SULFIDE |
