Hlanganyela Izandla ne-Kazakhstan ukuze Udale Imboni Yezimayini Yegolide Eqhakazile

Egagasini elikhulayo lemboni yezimayini zegolide emhlabeni wonke echumayo, iKazakhstan ithatha isikhundla esibalulekile ngemithombo yayo ecebile yezimayini zegolide. Manje, ngentshiseko egcwele nobuqotho, siletha amakhemikhali ochwepheshe okukhipha igolide - iSodium Cyanide , kanye nezinsizakalo zobuchwepheshe eziphelele , sibheke phambili ekuhambeni eceleni kwamabhizinisi ezimayini zegolide eKazakhstan kanye nokuvula isahluko esisha ngokubambisana ekusetshenzisweni nasekukhishweni kwezimayini zegolide.

I. Ukuhlaziywa Okujulile Komgomo Wezobuchwepheshe Wokumba Igolide Le-Cyanide

Inqubo yokukhipha igolide i-Cyanide isetshenziswa kabanzi ensimini yokukhipha imayini yegolide, ngokusekelwe endleleni yayo yokusabela kwamakhemikhali eyingqayizivele nenhle kakhulu. Lapho isixazululo se -sodium cyanide (NaCN) sithintana ne-gold ore, uchungechunge lwezimpendulo eziyinkimbinkimbi nezihlelekile lwenzeka buthule.

Okokuqala, endaweni ezungezile umoya, i-Sodium cyanide idlula ku-hydrolysis ebuthakathaka emanzini ukuze ikhiqize ama-ion e-cyanide (CN⁻). Ngokuhlanganyela komoya-mpilo emoyeni, igolide lidlula ku-complexation reaction nama-ion e-cyanide. I-chemical reaction equation ithi: 4Au + 8NaCN + O₂ + 2H₂O = 4NaAu(CN)₂ + 4NaOH. Kulokhu kusabela, igolide liyashiswa libe ama-ion egolide e-monovalent (Au⁺) futhi lakha i-complex eqinile - i-sodium dicyanoaurate (NaAu(CN)₂) enama-ion e-cyanide, ngaleyo ndlela lenza igolide lincibilike esixazululweni.

Okulandelayo, igolide elincibilikisiwe kusixazululo lidinga ukukhishwa. Enye yezindlela ezisetshenziswa kakhulu i-zinc powder replacement method. Lapho i-zinc powder (Zn) yengezwe kwisixazululo esiqukethe i-sodium dicyanoaurate, ngenxa yomsebenzi wensimbi onamandla we-zinc kunegolide, ukusabela okulandelayo kokubuyisela kwenzeka: 2NaAu (CN) ₂ + Zn = 2Au + Na₂Zn (CN) ₄. Kule nqubo, ama-ion egolide esixazululweni athathelwa indawo yi-zinc kanye ne-precipitate ngendlela yegolide eliyisisekelo, ngaleyo ndlela kuzuzwe ukukhishwa kwegolide.

Enye indlela evame ukusetshenziswa yindlela ye-activated carbon adsorption. Ikhabhoni ecushiwe inendawo enkulu ethize kanye nesakhiwo esicebile se-microporous, futhi inamandla okukhangisa ama-ion e-dicyanoaurate (Au(CN)₂⁻). Lapho ikhambi eliqukethe izakhi zegolide lidlula kumbhede wekhabhoni ocushiwe, izakhiwo zegolide ziyakhangiswa ebusweni bekhabhoni ecushiwe. Bese, ngezinqubo ezilandelayo ezifana ne-desorption ne-electrolysis, igolide liyahlukaniswa nekhabhoni ecushiwe ukuze kutholwe igolide elimsulwa.

II. Izinzuzo Zenqubo Yegolide Ye-Cyanide Ziyabonakala

1. Inzuzo Yezindleko Ezibalulekile

Njengekhemikhali ebalulekile enqubweni yokukhipha igolide le-cyanide, intengo ye-sodium cyanide izinzile futhi izindleko zayo zingalawulwa ekukhiqizweni okukhulu. Lokhu kwenza amabhizinisi ezimayini zegolide akwazi ukulawula ngempumelelo izindleko zokukhipha ngesikhathi sokukhiqizwa nokusebenza kwesikhathi eside, futhi athuthukise izinzuzo zomnotho. Uma kuqhathaniswa nezinye izinto ezibizayo ezidingekayo kwezinye izinqubo zokukhipha igolide, i- Cost Advantage ye-sodium cyanide iyabonakala, inciphisa ingcindezi yezezimali kumabhizinisi futhi ithuthukisa ukuncintisana kwawo emakethe.

2. Ukusebenza Kwegolide Okuphakeme Kakhulu

Inqubo yokukhipha igolide ye-cyanide inamandla amakhulu kakhulu okuncibilikisa igolide futhi ingakhipha igolide ngokuphelele ore. Ngaphansi kwezimo zenqubo ezifanele, izinga lokuthola igolide lingafinyelela izinga eliphezulu kakhulu, okusho ukuthi amabhizinisi angathola igolide elengeziwe ngenani elifanayo lensimbi, lithuthukise kakhulu izinga lokusetshenziswa kwezinsiza nokudala inani elengeziwe lamabhizinisi.

3. Inqubo Evuthiwe Nezinzile

Ngemuva kweminyaka yokuthuthuka nokusebenza, inqubo yokukhipha igolide ye-cyanide isivuthiwe impela. Inqubo yayo yokusebenza isezingeni futhi ochwepheshe bangayibamba kalula. Lokhu kwenza amabhizinisi ezimayini zegolide asebenze ngokuzinza nangempumelelo ngesikhathi sokukhiqiza, kunciphisa izingozi zokukhiqiza kanye nokulahlekelwa okubangelwa ukungazinzi kwezobuchwepheshe kanye nokunciphisa ubungozi bokukhiqiza.

4. Ukuguquguquka Okubanzi

Le nqubo iyakwazi ukuzivumelanisa kahle nezinhlobo ezahlukene zamatshe egolide. Kungakhathaliseki ukuthi i-oxidized ore, i-sulfide ore noma i-mixed ore, ukukhishwa kwegolide okuphumelelayo kungatholakala ngokulungisa kahle imingcele yenqubo. Lokhu Kuguquguquka Okubanzi kwenza izimayini zegolide ezinezimo ezahlukahlukene zejiyoloji eKazakhstan zikwazi ukwamukela inqubo yokukhishwa kwegolide nge-cyanide futhi zinikeze ukusebenza okugcwele ezinzuzweni zazo zemithombo.

Inkampani yethu iqonda ngokujulile ukuthi imikhiqizo yekhwalithi ephezulu iyisisekelo sokubambisana, futhi izinsizakalo zobuchwepheshe ezijikelezayo ziwukhiye wokuqinisekisa ukukhiqizwa okushelelayo kwamabhizinisi ezimayini zegolide. Ngakho-ke, sisungule ithimba lezobuchwepheshe elakhiwe ochwepheshe abakhulu ukuze banikeze ukusekelwa okukodwa kobuchwepheshe kumabhizinisi ezimayini zegolide e-Kazakhstan.

Ekuqaleni kwephrojekthi, ithimba lethu lezobuchwepheshe lizokwenza inhlolovo ejulile ye-geological endaweni kanye nokuhlaziya insimbi ezimayini zegolide, futhi ngokuhlolwa kokuhlomula, lenze ngendlela oyifisayo izinhlelo zenqubo yokukhipha igolide ezilungele amabhizinisi ukuze kuqinisekiswe ukuba nokwenzeka nokusebenza kahle okuphezulu kwenqubo.

Ngesikhathi senqubo yokukhiqiza, abasebenzi bethu bezobuchwepheshe bazohlinzeka ngomhlahlandlela ogcwele, futhi baxazulule ngokushesha izinkinga amabhizinisi ahlangabezane nazo ekulungiseni amaphutha, izinqubo zokusebenza, nokulawula ipharamitha. Futhi sizohlinzeka njalo ngokuqeqeshwa kochwepheshe kubasebenzi bezobuchwepheshe kanye nabasebenzayo bamabhizinisi ukuze sibasize ngokuqhubekayo bathuthukise amazinga abo obuchwepheshe namakhono okusebenza, siqinisekise ukusebenza okuzinzile kwenqubo yokukhiqiza.

Mayelana nokugcinwa kwemishini kamuva, sinethimba elilungisa izinto zokusebenza elinganikeza amabhizinisi izinsizakalo ezifana nokuhlolwa njalo kwemishini, ukunakekelwa, nokuxazulula izinkinga, liqinisekise ukuthi okokusebenza kuhlala kusesimweni esihle sokusebenza, kunweba isikhathi sokusebenza kwemishini, kanye nokunciphisa izindleko zokugcinwa kwemishini yamabhizinisi.

Bangane abathandekayo bebhizinisi lezimayini zegolide eKazakhstan, sikumema ngobuqotho ukuthi usebenzisane nathi. Ukukhetha imikhiqizo yethu ye-sodium cyanide kanye nezinsizakalo zobuchwepheshe kusho ukukhetha uchwepheshe, ukusebenza kahle okuphezulu, nokuthula kwengqondo. Masibonise amathalente ethu emkhakheni wezimayini zegolide, ngokuhlanganyela sidale impumelelo ekhaliphile, futhi sibambe iqhaza ekuthuthukisweni kwemboni yezimayini zegolide e-Kazakhstan!
