Joyina izandla kunye neKazakhstan ukwenza ishishini leGolide eliqaqambileyo

Kwilixa elikhulayo leshishini lemigodi yegolide kwihlabathi liphela elikhulayo, iKazakhstan ikwindawo ebalulekileyo ngenxa yemithombo yayo etyebileyo yemigodi yegolide. Ngoku, ngenzondelelo epheleleyo nokunyaniseka, sizisa iikhemikhali zobuchwephesha zokukhupha igolide - iSodium Cyanide , kunye neeNkonzo zobuGcisa ezipheleleyo , sijonge phambili ekuhambeni kunye namashishini emigodi yegolide eKazakhstan kunye nokuvula isahluko esitsha ekusetyenzisweni nasekukhutshweni kwemigodi yegolide.

I. Uhlalutyo olunzulu loMgaqo woBugcisa weCyanide Gold Extraction

Inkqubo yokuQokelelwa kweGolide yeCyanide isetyenziswa kakhulu kwicandelo lokuqokelelwa kwemigodi yegolide, ngokusekelwe kwindlela yayo ekhethekileyo neyobuchule yokusabela kwamakhemikhali. Xa isisombululo se -sodium cyanide (NaCN) sidibana negolide ore, uthotho lweempendulo ezintsonkothileyo nezicwangcisiweyo zenzeka ngokuzolileyo.

Okokuqala, kwindawo ene-aerobic, iSodium cyanide idlula kwi-hydrolysis ebuthathaka emanzini ukuze ivelise i-ions ze-cyanide (CN⁻). Ngokuthatha inxaxheba kweoksijini emoyeni, igolide idlula kwi-complexation reaction kunye ne-ions ze-cyanide. I-equation ye-chemical reaction yi: 4Au + 8NaCN + O₂ + 2H₂O = 4NaAu(CN)₂ + 4NaOH. Kule reaction, igolide i-oxidized ibe yi-ions zegolide ze-monovalent (Au⁺) kwaye yenza i-complex eqinileyo - i-sodium dicyanoaurate (NaAu(CN)₂) ene-ions ze-cyanide, 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

Njengekhemikhali ephambili kwinkqubo yokukhupha igolide ye-cyanide, ixabiso le-sodium cyanide lizinzile kwaye iindleko zalo zinokulawulwa kwimveliso enkulu. Oku kwenza amashishini emigodi yegolide akwazi ukulawula ngokufanelekileyo iindleko zokukhupha ngexesha lemveliso kunye nokusebenza kwexesha elide, kwaye aphucule iingenelo zoqoqosho. Xa kuthelekiswa nezinye ii-reagents ezibizayo ezifunekayo kwezinye iinkqubo zokukhupha igolide, i- Cost Advantage ye-sodium cyanide iyabonakala, inciphisa uxinzelelo lwezemali kumashishini kwaye iphucula ukhuphiswano lwawo 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 iyakwazi ukuziqhelanisa neentlobo ezahlukeneyo zeentsimbi zegolide. Nokuba yi-oxidized ore, i-sulfide ore okanye i-mixed ore, ukukhupha igolide okusebenzayo kunokufezekiswa ngokulungelelanisa ngokufanelekileyo iiparameter zenkqubo. Olu hlengahlengiso olubanzi luvumela imigodi yegolide eneemeko ezahlukeneyo zejoloji eKazakhstan ukuba yamkele inkqubo yokukhupha igolide ye-cyanide kwaye inike amandla apheleleyo kwizibonelelo zayo zemithombo.
