Lonke udaka lwecyanide leaching yinkqubo yakudala nethembekileyo yokutsalwa kwegolide, esetyenziswa kakhulu kwimveliso namhlanje.Kwiminyaka yakutshanje, ukuze kwandiswe imveliso yegolide, ukuqonda imveliso yegolide kwindawo, kunye nokwandisa ukusebenza kakuhle kwemveliso yamashishini, imigodi yegolide eyahlukeneyo yandise umda wesicelo senkqubo yabo yodaka lwecyanide.
Amasuntswana egolide afakwe kwiintsimbi ezahlukeneyo ubukhulu becala yigolide ephakathi kunye necolekileyo, kwaye imeko yegolide ubukhulu becala yigolide ye-intergranular kunye negolide ye-fissure.Lo mbuso uhlonyelweyo ulungele ukuvuza ngokupheleleyo kodaka lwecyanide, kodwa kusekho umlinganiselo omncinci wamasuntswana acolekileyo asongelwe ngegolide kwii-ores ezahlukeneyo, eziya kuba neempembelelo ezithile kwisantya sokuvuza kwegolide.Iziphumo zophando ngezimbiwa zibonisa ukuba uhlobo ngalunye lwentsimbi ekrwada luyintsimbi ekrwada ekunzima ukuyivuthulula, kwaye isixa esikhulu se-cyanide sisetyenziswa ngexesha lokuvuza kwe-cyanide, echaphazela izinga lokuvuza kwegolide.
Inkqubo eqhelekileyo yokuvuza yecyanide yodaka ayityi nje kuphela icyanide eninzi, kodwa inesantya esisezantsi sokuvuza kwentsimbi ekrwada ephakathi kunye nephezulu yesulfide equlethe izinto ezininzi ezingcolileyo ezinjengobhedu, iarsenic, nesalfure.Ukongeza i-nitrate ekhokelayo yokunyangwa kwangaphambili ngaphambi kokuba i-leaching inokunciphisa ilahleko ye-cyanide kwaye yandise izinga lokuvuza.
Ukongeza i-nitrate ekhokelayo ngaphambi kokuba i-leaching inokunciphisa umxholo weengqungquthela zetsimbi ezinyibilikayo kwi-slurry, ngaloo ndlela ukunciphisa ukusetyenziswa kwe-sodium cyanide.Kwimigodi yegolide, thatha i-ore-type high-flavor pyrrhotite-type gold-2-copper ore njengomzekelo.Umxholo wepyrrhotite ufikelela kwi-23130%.Kulwakhiwo lwemolekyuli yepyrrhotite, kukho iathom yesulfure ebotshelelwe buthathaka ngokulula kwi-oxidized ukwenza i-soluble sulfide, edla isixa esikhulu se-cyanide ngexesha lenkqubo ye-cyanide leaching kwaye yandise ixesha lonyango lwangaphambili.Kwaye ukongezwa kwe-nitrate ye-lead kunokunciphisa ubukho be-sulfide ions kwi-slurry kunye ne-sulfide e-soluble e-soluble, ngaloo ndlela ukunciphisa ukusetyenziswa kwe-sodium cyanide kunye nokuphucula izinga lokuhlamba.
