Izinto eziluncedo kunye nezingeloncedo zeSodium Cyanide kwiGold Leaching

Kwishishini lemigodi yegolide, inkqubo yokukhupha igolide ibaluleke kakhulu. I-sodium cyanide ibisoloko iyinto ebalulekileyo kwinkqubo yokukhupha igolide . Ukuqonda iingenelo kunye nokungalungi kwayo kubalulekile kubavukuzi kunye nabazingqongileyo, njengoko inceda ekwenzeni izigqibo ezinolwazi malunga nokusetyenziswa kwayo okuqhubekayo kunye nokuphonononga ezinye iindlela.

1. Izinto eziluncedo zeSodium Cyanide kwiGold Leaching

Ubuchule obuphezulu bokuNyekiswa kweGolide

Enye yezona nzuzo zibalulekileyo zoko

I-dum cyanide ekutsaleni igolide kukusebenza kwayo okuphezulu ekunyibilikiseni igolide. Ii-ion ze-cyanide zenza ii-complexes ezizinzileyo ngee-ion zegolide. Oku kuvumela ukukhutshwa kwegolide kwi-ores ezikumgangatho ophantsi. Impendulo yeekhemikhali phakathi kwegolide, ioksijini, kunye ne -sodium cyanide kwisisombululo samanzi ingamelwa ngolu hlobo:

4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH. Le ndlela yokusabela yenza ukuba kutsalwe ngokupheleleyo igolide, nto leyo eyenza ukuba imveliso ifumaneke kwiintsimbi ezikrwada.

Iindleko - Ukusebenza kakuhle

I-sodium cyanide ixabisa kakuhle xa ithelekiswa nezinye iindlela zokukhupha inkunkuma. Inkqubo yayo yokuvelisa izinzile, kwaye ifumaneka ngokulula ngobuninzi. Iinkampani zemigodi zingathenga i-Sodium Cyanide ngexabiso elifanelekileyo, nto leyo ibalulekileyo ekugcineni inzuzo, ingakumbi xa zisebenza kwimisebenzi emikhulu. Ukongeza, izixhobo ezilula ezifunekayo kwinkqubo yokukhupha inkunkuma ye-cyanide zinciphisa iindleko.

Ukuhambelana neentlobo ezahlukeneyo zentsimbi

I-sodium cyanide ingasetyenziselwa uluhlu olubanzi lwegolide-ethwele i-ores. Nokuba intsimbi ekrwada isimahla - iyasila okanye iqulethe iiminerali ezintsonkothileyo zesulfide, i-cyanide leaching ihlala iphuculwa ukuze kukhutshwe igolide. Oku bhetyebhetye kwenza kube lukhetho olukhethwayo kwimisebenzi emininzi yemigodi kwihlabathi jikelele, njengoko kunciphisa imfuno ye-ore ebiza kakhulu - iindlela ezithile zokucubungula.

2. Ububi beSodium Cyanide kwiGold Leaching

Ubungozi bendalo esingqongileyo

Eyona ngxaki ibalulekileyo yeSodium cyanide bubuthi bayo obugqithisileyo. I-Cyanide iyingozi kakhulu kwizilwanyana zasemanzini, iintaka, kunye nezilwanyana ezincancisayo. Xa i-cyanide ichitheka kwindawo yokumba, inokungcolisa imithombo yamanzi ekufutshane, nto leyo ekhokelela ekufeni kweentlanzi kunye nezinye izinto eziphilayo zasemanzini. Nokuba yi-cyanide encinci emanzini inokuphazamisa yonke inkqubo yendalo. Umzekelo, i-cyanide inokuthintela ukusebenza kwe-cytochrome c oxidase kwiiseli, ithintele ukusetyenziswa kweoksijini okuqhelekileyo ekuphefumleni kwe-aerobic.

IiMfuno eziQhelekileyo zoLawulo

Ngenxa yobutyhefu bayo, ukusetyenziswa kwe-sodium cyanide kwimigodi yegolide kuxhomekeke kwimimiselo engqongqo. Iinkampani zemigodi kufuneka zenze utyalo-mali kwiinkqubo zokulawula inkunkuma ezintsonkothileyo ukuthintela i-cyanide ekungeneni kokusingqongileyo. Kufuneka baphumeze iinkqubo zokubeka iliso ukuqinisekisa ukuba amanqanaba e-cyanide emanzini nasemoyeni aphakathi kwemida eyamkelekileyo. Ezi mfuno zolawulo zonyusa iindleko zokusebenza kweenkampani zemigodi, njengoko kufuneka zabe izixhobo zokuthobela imimiselo.

Imingcipheko yeMpilo kubasebenzi

Abasebenzi ababandakanyekayo kwinkqubo yokukhutshwa kwegolide usebenzisa i-sodium cyanide basengozini yokuvezwa. Ukuphefumla okanye ukudibana nolusu kunye ne-cyanide kunokubangela iingxaki ezinzulu zempilo, kubandakanya intloko ebuhlungu, isiyezi, isicaphucaphu, kwaye kwiimeko ezinzima, ukufa. Iinkampani zemigodi kufuneka zibonelele ngoqeqesho olubanzi lokhuseleko kunye nezixhobo zokhuselo lobuqu kubasebenzi bazo ukunciphisa le mingcipheko. Nangona kunjalo, iingozi zisengenzeka, nto leyo ebeka ubomi babasebenzi esichengeni.

Ukuqukumbela, i-sodium cyanide ibonelela ngeengenelo ezahlukileyo ngokwendlela yokusebenza kakuhle, iindleko-ukusebenza, kunye nokuhambelana kwe-ore kwinkqubo yokukhutshwa kwegolide. Nangona kunjalo, iingozi zayo zokusingqongileyo, iimfuno ezingqongqo zolawulo, kunye nemingcipheko kwimpilo yabasebenzi ayinakuhoywa. Njengoko ishishini lemigodi liqhubela phambili, kukho imfuneko ekhulayo yokuphuhlisa ezinye iindlela zokufundisa ezihambelana nokusingqongileyo kunye noqoqosho olusebenzayo, ngelixa kugcinwe imigangatho yomgangatho ophezulu wokutsalwa okuphunyeziweyo ngoku ngesodium cyanide.
