Umkhuba Wokulungisa Indawo Yokwengeza Ye-Sodium Cyanide Kunqubo Yegolide Ye-Cyanidation

Embonini yezimayini zegolide , inqubo ye-Cyanidation idlala indima ebalulekile ekukhipheni igolide ku-ore. Esikhungweni se-carbon-in-pulp (CIP) esincane esingama-t/d semayini ethile yegolide, kwenziwe ukulungiswa okukhulu mayelana nendawo yokwengeza i -Sodium cyanide , okulethe izinguquko eziphawulekayo ekusebenzeni kokukhiqiza.

Isingeniso

Inqubo yokuqala yesitshalo se-CIP sale mayini yegolide yayihilela ukufaka i-Sodium Cyanide endaweni ethile ethangini lokukhukhumeza. Kodwa-ke, emzamweni wokwenza ngcono inqubo yokukhipha iGolide , ukuthuthukisa izinkomba zenqubo, nokuthuthukisa ukusebenza kahle kwezomnotho, kwenziwa isinqumo sokulungisa indawo yokwengeza i- sodium cyanide . Indlela entsha ukufaka i-sodium cyanide ngemuva kwezigaba ezimbili zokugaya.

Imininingwane Yokulungiswa Kwenqubo

Umsebenzi wokugaya izigaba ezimbili ekucutshungulweni kwetshe legolide kuyisinyathelo esibalulekile sokukhulula izinhlayiya zegolide ku-matrix ye-ore. Ngokungeza i-sodium cyanide ngokushesha ngemva kwalezi zigaba ezimbili zokugaya, kulindeleke ukuthi ama-ion e-cyanide ahlangane nezindawo zegolide ezisanda kuvezwa ngempumelelo. Lokhu kungenxa yokuthi inqubo yokugaya iveza izinhlayiya zegolide ezengeziwe, futhi ukufakwa ngesikhathi kwe-sodium cyanide kuvumela ukusabela okushesha nokusebenza kahle kakhudlwana. Endleleni yasekuqaleni yokwengeza i-sodium cyanide ethangini elinyakazayo, kwakunesikhathi esithile ngaphambi kokuba i-cyanide ihlangane nezinhlayiya zegolide, futhi elinye igolide lalingase lingafinyeleleki kancane ngenxa yokuba khona kwamanye amaminerali noma ukuhlangana kwezinhlayiya.

Ukuhlolwa Kwezikhombisi Zenqubo

Igolide Lokubuyisela Izinga

Ngemva kokulungiswa kwendawo yokwengeza i-sodium cyanide, kwaba nokuthuthuka okuphawulekayo kwezinga lokutholwa kwegolide. Ukuxhumana okuqondile phakathi kwezinhlayiya ze-cyanide negolide kwaholela ekuhlakazweni okuphelele kwegolide. Enqubweni yangaphambilini, izinga lokutholwa kwegolide liguquguquke cishe ku-[X]%. Kodwa-ke, ngendlela entsha yokwengeza, izinga lokuthola kabusha liye lenyuka kancane kancane lafinyelela cishe ku-[X + Y]%, okubonisa ukukhishwa okuphumelelayo kwegolide etsheni.

Ukuhlanzeka komkhiqizo wegolide

Ngaphezu kwesilinganiso sokubuyisela, ukuhlanzeka komkhiqizo wegolide nakho kubonise ushintsho oluhle. Inqubo eyenziwe kahle yehlise ukukhishwa ngokubambisana kokunye ukungcola, njengoba ukungezwa kwangaphambilini kwe-sodium cyanide kuvumela ukusabela okukhetheke kakhulu ngegolide. Ukuhlanzeka komkhiqizo wokugcina wegolide kukhuphuke ukusuka [kumaphesenti okuhlanzeka kwangempela] kuya [kumaphesenti amasha wokuhlanzeka], okubaluleke kakhulu ekuthuthukiseni ikhwalithi yomkhiqizo wegolide kanye nenani lawo lemakethe.

Ukuhlaziywa Kwezindleko Zokukhiqiza

Ukusetshenziswa kwe-sodium cyanide

Enye yezinto ezikhathazayo ezinkulu enqubweni ye-cyanidation ukusetshenziswa kwe-sodium cyanide. Ngokumangalisayo, ngemva kokulungiswa kwendawo yokwengeza, ukusetshenziswa kwe-sodium cyanide kwehle. Enqubweni yasekuqaleni, ngenxa yokuxhumana okuncane okusebenzayo nezinhlayiya zegolide, inani elikhulu kakhulu le-sodium cyanide lalidingeka ukuze kuqinisekiswe ukusabela okwanele. Kodwa-ke, ngendlela entsha, ukungezwa okuhloswe kakhulu kwe-sodium cyanide kuholele ekusetshenzisweni okuphumelelayo. Ukusetshenziswa kwe-sodium cyanide ngethani le-ore kwehle ukusuka [inani lokusetshenziswa kwangempela] kuya [inani elisha lokusetshenziswa], okuholele ekongeni kwezindleko ezinkulu.

Ukusetshenziswa Kwamandla

Nakuba indawo yokwengeza ye-sodium cyanide yashintsha, ukusetshenziswa kwamandla okuphelele kwenqubo akuzange kukhule. Eqinisweni, ngokwezinga elithile, ukusetshenziswa kwamandla okuhlobene nokuyaluza esigabeni sakamuva senqubo kwehle kancane. Lokhu kungenxa yokuthi ukusabela okusebenza kahle kakhulu esigabeni sangaphambilini kunciphise isidingo sokuyaluza ngokweqile ethangini elinyakazayo ukuze kuthuthukiswe ukusabela phakathi kwe-cyanide negolide.

Izinzuzo Zomnotho

Izindleko zokulondolozwa

Ukwehliswa kokusetshenziswa kwe-sodium cyanide kwaholela ngokuqondile ekongeni kwezindleko. Uma kucatshangelwa ukukhiqizwa kwezinga elikhulu kwemayini yegolide, ngisho nokuncipha okuncane kokusetshenziswa kwe-sodium cyanide ngethani le-ore kungaqongelela inani elikhulu ngokuhamba kwesikhathi. Ngaphezu kwalokho, ukwehla kancane kokusetshenziswa kwamandla nakho kube nomthelela ekongeni izindleko. Sekukonke, ukonga kwezindleko zanyanga zonke kufinyelele [inani elithile], okuwukuthuthukiswa okuphawulekayo kwesakhiwo sezindleko zemayini yegolide.

Imali Ekhuphukile

Izinga eliphezulu lokutholwa kwegolide kanye nokuhlanzeka okuthuthukisiwe komkhiqizo wegolide kwaletha imali eyengeziwe. Ngezinga eliphezulu lokuthola kabusha, igolide elengeziwe lakhiqizwa ngenani elifanayo lensimbi. Futhi ukuhlanzeka okuthuthukisiwe kwakusho ukuthi umkhiqizo wegolide ungathengiswa ngentengo engcono emakethe. Umphumela ohlangene walezi zici ezimbili uholele ekwenyukeni okukhulu kwemali engenayo yanyanga zonke yemayini yegolide, yafinyelela [inani elithile].

Isiphetho

Ukulungiswa kwendawo yokwengezwa kwe-sodium cyanide ohlelweni lwegolide lwe-cyanidation yalesi sitshalo esincane se-CIP esingu-30 t/d kubonise imiphumela emihle emangalisayo. Ngokombono wezinkomba zenqubo, kokubili izinga lokutholwa kwegolide kanye nokuhlanzeka komkhiqizo wegolide kwenziwe ngcono. Mayelana nezindleko zokukhiqiza, ukusetshenziswa kwe-sodium cyanide kwehlile, futhi kube nokuncishiswa okuncane kokusetshenziswa kwamandla. Lezi zinguquko ekugcineni zihumushe ezinzuzweni ezibalulekile zezomnotho, ngakho kokubili ukonga izindleko kanye nemali engenayo eyengeziwe. Lo mkhuba uhlinzeka ngolwazi olubalulekile kwezinye izimayini zegolide uma kucatshangelwa ukuthuthukiswa kwenqubo enqubweni ye-cyanidation, futhi kukhombisa ukuthi ukulungiswa okulula kodwa okucatshangelwe kahle endaweni yokwengezwa yama-reagents abalulekile kungaba nomthelela omuhle kakhulu ekukhiqizeni kukonke kanye nokusebenza komnotho kwemayini yegolide.
