Joyina izandla kunye neKazakhstan ukwenza ishishini leGolide eliqaqambileyo

Kwinqanaba elikhulayo loshishino lomgodi wegolide kwihlabathi, iKazakhstan ikwindawo ebaluleke kakhulu ngezixhobo zayo ezityebileyo zomgodi wegolide. Ngoku, ngolangazelelo olupheleleyo kunye nokunyaniseka, sizisa iikhemikhali ezivuzayo zegolide - Isodium cyanide, kunye nokubanzi Iinkonzo Zobugcisa, ndijonge phambili ekuhambeni ecaleni namashishini omgodi wegolide eKazakhstan kwaye ngokudibeneyo avule isahluko esitsha kuxhaphazo kunye nokutsalwa komgodi wegolide.

I. Uhlalutyo olunzulu loMgaqo woBugcisa weCyanide Gold Extraction

The ICyanide Gold Extraction Inkqubo isetyenziswa ngokubanzi kwibala lokutsalwa komgodi wegolide, ngokusekwe kwindlela yayo ekhethekileyo negqwesileyo yokusabela kweekhemikhali. Nini sodium cyanide (NaCN) isisombululo sidibana nentsimbi yegolide, uthotho lweempendulo ezintsonkothileyo nezicwangcisiweyo zenzeka ngokuzolileyo.

Okokuqala, kwindawo ye-aerobic, Isodium cyanide ufumana i-hydrolysis ebuthathaka emanzini ukuvelisa i-cyanide ions (CN⁻). Ngokuthatha inxaxheba kwe-oksijini emoyeni, igolide ifumana impendulo eyinkimbinkimbi kunye ne-cyanide ions. I-equation ye-chemical reaction equation yile: 4Au + 8NaCN + O₂ + 2H₂O = 4NaAu(CN)₂ + 4NaOH. Kule mpendulo, igolide i-oxidized kwi-ion zegolide e-monovalent (Au⁺) kwaye yenza i-complex ezinzileyo-i-sodium dicyanoaurate (NaAu(CN)₂) ene-cyanide ion, ngaloo ndlela yenza igolide inyibilike kwisisombululo.

Emva koko, igolide echithwe kwisisombululo kufuneka ikhutshwe. Enye yeendlela ezisetyenziswa ngokuqhelekileyo yi-zinc powder replacement method. Xa i-zinc powder (Zn) yongezwa kwisisombululo esine-sodium dicyanoaurate, ngenxa yomsebenzi onamandla wesinyithi we-zinc kuneyegolide, le mpendulo yokutshintshwa ilandelayo iyenzeka: 2NaAu (CN) ₂ + Zn = 2Au + Na₂Zn (CN) ₄. Kule nkqubo, i-ion zegolide kwisisombululo zitshintshwa yi-zinc kunye ne-precipitate ngendlela yegolide ye-elemental, ngaloo ndlela ifezekisa ukukhutshwa kwegolide.

Enye indlela esetyenziswa ngokuqhelekileyo yindlela ye-carbon adsorption esebenzayo. Ikhabhoni esebenzayo inommandla omkhulu ocacileyo kunye nesakhiwo esityebileyo se-microporous, kwaye inomthamo owomeleleyo we-adsorption ye-dicyanoaurate ion (Au(CN)₂⁻). Xa isisombululo esiqulethe izinto zegolide sidlula kwibhedi yekhabhoni esebenzayo, iikhompleksi zegolide zibhengezwa kumphezulu wekhabhoni esebenzayo. Ke, ngeenkqubo ezilandelayo ezinje nge-desorption kunye ne-electrolysis, igolide iyahlulwa kwikhabhoni esebenzayo ukufumana igolide esulungekileyo.

II. Izinto eziluncedo zeCyanide Gold Extraction Process ziyabonakala

1. I-Advantage yeendleko eziBalulekileyo

Njengomchiza ophambili kwinkqubo yokukhutshwa kwegolide yecyanide, ixabiso le-sodium cyanide lizinzile kwaye ixabiso layo linokulawulwa kwimveliso enkulu. Oku kwenza ukuba amashishini omgodi wegolide akwazi ukulawula ngokufanelekileyo iindleko zokugrunjwa ngexesha lexesha elide lemveliso nokusebenza, kunye nokuphucula izibonelelo zoqoqosho. Xa kuthelekiswa nezinye ii-reagents ezibizayo ezifunwa zezinye iinkqubo zokutsalwa kwegolide, i Iindleko ze-Advantage i-sodium cyanide ibonakala ngokwayo, inciphisa uxinzelelo lwezemali kumashishini kunye nokuphucula ukukhuphisana kwabo kwimarike.

2. UkuSebenza kweGolide okuPhezulu kakhulu

Inkqubo yokutsalwa kwegolide yecyanide inamandla kakhulu okunyibilikisa igolide kwaye inokukhupha ngokupheleleyo igolide kwintsimbi ekrwada. Phantsi kweemeko zenkqubo efanelekileyo, izinga lokubuyiselwa kwegolide linokufikelela kwinqanaba eliphezulu, nto leyo ethetha ukuba amashishini anokufumana igolide eyongezelelekileyo kumlinganiselo ofanayo wentsimbi ekrwada, ephucula kakhulu izinga lokusetyenziswa kobutyebi nokudala ixabiso elingakumbi kumashishini.

3. Inkqubo Evuthiweyo neZinzileyo

Emva kweminyaka yophuhliso kunye nokuziqhelanisa, inkqubo yokutsalwa kwegolide yecyanide sele ikhulile. Inkqubo yokusebenza kwayo isemgangathweni kwaye amagcisa anokuyilawula ngokulula. Oku kunceda amashishini omgodi wegolide ukuba asebenze ngokuzinzileyo nangokufanelekileyo ngexesha lenkqubo yemveliso, ukunciphisa iingozi zemveliso kunye nelahleko ebangelwa kukungazinzi kobugcisa kunye nokunciphisa imingcipheko yemveliso.

4. Ukuguquguquka okubanzi

Le nkqubo inokuziqhelanisa kakuhle neentlobo ezahlukeneyo zeentsimbi zegolide. Nokuba yintsimbi ekrwada ene-oxidized, i-sulfide ore okanye i-ore exutyiweyo, ukutsalwa kwegolide okusebenzayo kunokufezekiswa ngokulungelelanisa ngokufanelekileyo iiparamitha zenkqubo. Oku Ukuguquguquka okubanzi yenza imigodi yegolide eneemeko ezahlukeneyo zejoloji eKazakhstan ukuba yamkele inkqubo yokutsalwa kwegolide yecyanide kwaye idlale ngokupheleleyo kwiinzuzo zabo zemithombo.

III. Zonke - ngeenxa zonke Iinkonzo zobuGcisa Ukukhatshwa

Inkampani yethu iyaqonda ngokunzulu ukuba iimveliso ezikumgangatho ophezulu zisisiseko sentsebenziswano, kwaye zonke-iinkonzo zobugcisa ezijikelezayo zingundoqo ekuqinisekiseni imveliso egudileyo yamashishini omgodi wegolide.
