4.3 Indima yeSodium Cyanide eMgodini

Isodium cyanide idlala indima ebaluleke kakhulu kwishishini lemigodi, ngakumbi ekukhutshweni kweentsimbi ezixabisekileyo, ukutsalwa kwegolide kungumzekelo obalaseleyo.

Inkqubo yokusebenzisa i-sodium cyanide ukukhupha igolide kwi-ore ibizwa ngokuba yi-cyanidation. Okokuqala, intsimbi ekrwada iculwa ibe ngumgubo ocolekileyo kusetyenziswa oomatshini boshishino. Oku kwandisa ummandla wentsimbi ekrwada, nto leyo eyenza ukuba ifikeleleke ngakumbi kwiintshukumo zemichiza ezilandelayo. Emva koko, i-ore powder yongezwa kwisisombululo se-sodium - cyanide (NaCN). Ebukhoneni be-oksijeni, ukuphendulwa kweekhemikhali kwenzeka: 4Au + 8NaCN + O₂ + 2H₂O = 4Na[Au (CN)₂] + 4NaOH. Kule mpendulo, iimolekyuli zegolide zenza ibhondi eyomeleleyo kunye ne-NaCN, zenza igolide enyibilikayo - i-cyanide complex, iNa[Au (CN)) ₂]. Le ngqungquthela ivumela igolide ukuba inyibilike kwisisombululo, iyahlula kwezinye iindawo ze-ore.

Emva kokuba igolide ichithwe kwisisombululo se-cyanide, isinyathelo esilandelayo kukubuyisela igolide. Oku kwenziwa ngokuqhelekileyo kusetyenziswa i-zinc. I-Zinc iphendula ngegolide - i-cyanide complex kwisisombululo. Ukusabela kwemichiza yi-2 [Au (CN)₂]⁻+Zn = 2Au + [Zn (CN)₄]²⁻. Ngale ndlela yokusabela, iimolekyuli ze-cyanide zahlulwa kwigolide, kwaye igolide iguqulwa ibuyele kwisimo esiqinileyo, ilungele inkqubo elandelayo ye-熔炼 (ukunyibilikisa). Kwinkqubo yokunyibilikisa, igolide eqinileyo iyacocwa ngakumbi kwaye inyibilikiswe ukuze kufumaneke iingots zegolide ezisulungekileyo.

Ukusetyenziswa kwe-sodium cyanide kwi-extraction yegolide kuxabiswa kakhulu kuba iphucula kakhulu isinyithi - izinga lokubuyisela. Xa kuthelekiswa nezinye iindlela, i-cyanidation inokukhupha igolide ngokufanelekileyo kwi-ores yomgangatho ophantsi, ebikade ithathwa njengengenaqoqosho kum.
