Mokhoa o sebetsang oa sodium cyanide joalo ka ho tepella maikutlo

Sodium cyanide (NaCN) ke ntho e sithabetsang haholo bakeng sa liminerale tsa sulfide tse kang chalcopyrite (copper ore). Ka tsamaiso ea flotation, Sodium cyanide e ikarola ka metsing ho lokolla li-ion tsa cyanide (CN⁻). Li-ion tsena tsa cyanide li ka sebetsana le li-ion tsa tšepe holim'a liminerale tsa koporo. Ka mohlala, ka chalcopyrite (CuFeS₂), li-ion tsa cyanide li ka etsa metsoako e tsitsitseng ea tšepe-cyanide. Karabo e ka emeloa ka tsela e latelang:

CuFeS₂ + 4CN⁻ → Cu(CN)₄²⁻ + FeS₂ + 2e⁻

Karabelo ena ka katleho e qhaqha li-ion tsa koporo holim'a chalcopyrite, ho etsa lera la hydrophilic la li-complexes tsa koporo-cyanide. Ka lebaka leo, bokaholimo ba liminerale tsa koporo bo fetoha hydrophobic e fokolang, ho fokotsa bokhoni ba eona ba ho hokela li-bubble tsa moea ka seleng ea flotation. Ka lehlakoreng le leng, molybdenite (MoS₂), e leng liminerale tse ka sehloohong tse nang le molybdenum, e batla e sa kenelle ho li-ion tsa cyanide tlas'a maemo a tloaelehileng a ho phaphamala. Molybdenite e na le sebaka sa tlhaho sa hydrophobic ka lebaka la sebopeho sa eona se kolobisitsoeng, se lumellang hore se phaphame habonolo ke mokelli le libubble tsa moea nakong ea ts'ebetso ea ho phaphamala ha liminerale tsa koporo li tepeletse maikutlong. sodium cyanide.
