Izinto eziluncedo kunye nezingeloncedo zeSodium Cyanide kwiGold Leaching

Kwishishini lemigodi yegolide, inkqubo ye ukutsalwa kwegolide ibaluleke kakhulu. Isodium i-cyanide kudala yaba reagent engundoqo kwi ukuvuza kwegolide inkqubo. Ukuqonda izinto eziluncedo nezingeloncedo kuyo kubalulekile kubo bobabini abasebenzi-mgodini kunye neengcali zokusingqongileyo, njengoko inceda ekwenzeni izigqibo ezizizo malunga nokusetyenziswa kwayo okuqhubekayo nasekuphononongeni ezinye iindlela.

1. Izinto eziluncedo zeSodium Cyanide kwiGold Leaching

Ubuchule obuphezulu bokuNyekiswa kweGolide

Enye yezona nzuzo zibalulekileyo zoko

I-dum cyanide kwi-leaching yegolide kukusebenza kwayo okuphezulu ekunyibilikiseni igolide. Iiyoni ze-cyanide zenza ii-complexes ezizinzileyo ezineeyoni zegolide. Oku kuvumela ukutsalwa kwegolide nakweziintsimbi zodidi oluphantsi. Ukusabela kweekhemikhali phakathi kwegolide, ioksijini, kunye sodium cyanide kwisisombululo esinamanzi sinokumelwa 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 inexabiso elisebenzayo xa kuthelekiswa neearhente ezininzi ezizezinye ezitshintshayo. Inkqubo yokuvelisa kwayo imiselwe kakuhle, kwaye ifumaneka lula ngobuninzi. Iinkampani zemigodi zinokuthenga Isodium cyanide ngexabiso elifanelekileyo, elibalulekileyo ekugcineni inzuzo, ngakumbi xa ujongene nemisebenzi emikhulu. Ukongeza, izixhobo ezilula ezifunekayo kwinkqubo ye-cyanide leaching zinciphisa ngakumbi 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 drawback ibalulekileyo Isodium cyanide yityhefu yayo egqithisileyo. I-Cyanide iyingozi kakhulu kubomi basemanzini, iintaka kunye nezilwanyana ezanyisayo. Xa kuthe kwachitheka icyanide kwindawo yomgodi, inokungcolisa imithombo yamanzi ekufutshane, nto leyo ekhokelela ekufeni kweentlanzi nezinye izinto eziphila emanzini. Kwanomlinganiselo omncinci we-cyanide emanzini unokuphazamisa yonke i-ecosystem. Ngokomzekelo, i-cyanide inokuthintela umsebenzi we-cytochrome c oxidase kwiiseli, ukukhusela ukusetyenziswa okuqhelekileyo kwe-oksijini kwi-aerobic respiration.

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.
