Ukuziqhelanisa noLungiso lweNdawo eyoNgezelelweyo yeSodium Cyanide kwiNkqubo yeGold Cyanidation

Kwi Ishishini lemigodi yegolide, i Inkqubo ye-cyanidation idlala indima ebalulekileyo ekukhupheni igolide kwintsimbi ekrwada. Kwisityalo esincinci se-30 t/d se-carbon-in-pulp (CIP) somgodi othile wegolide, uhlengahlengiso olubalulekileyo lwenziwe malunga nesiza sokongeza Isodium cyanide, eye yazisa utshintsho oluphawulekayo ekusebenzeni kwemveliso.

intshayelelo

Inkqubo yokuqala yalo mgodi wegolide iCIP plant ibandakanye ukongeza Isodium cyanide ngexesha elinye kwitanki yokuphazamiseka. Nangona kunjalo, kwiinzame zokwandisa i Ukutsalwa kwegolide inkqubo, ukuphucula izikhombisi zenkqubo, kunye nokwandisa ukusebenza kakuhle kwezoqoqosho, isigqibo senziwe ukulungisa indawo yokongeza sodium cyanide. Indlela entsha yokongeza i-sodium i-cyanide emva kwamanqanaba amabini okusila.

Iinkcukacha zoLungiso lweNkqubo

Umsebenzi wokusila onamanqanaba amabini ekusetyenzweni kwentsimbi ekrwada linyathelo eliphambili lokukhulula amasuntswana egolide kwi-matrix ekrwada. Ngokudibanisa i-sodium cyanide ngokukhawuleza emva kwezi zigaba zimbini zokusila, kulindeleke ukuba ii-ion zecyanide zidibane nemigangatho yegolide esandula kuvezwa ngokusebenzayo ngakumbi. Oku kungenxa yokuba inkqubo yokusila iveza amasuntswana egolide angakumbi, kwaye ukongezwa kwangethuba kwesodium cyanide kuvumela ukusabela ngokukhawuleza nangempumelelo. Kwindlela yantlandlolo yokongeza i-sodium cyanide kwitanki yokuphazamiseka, bekukho ixesha elithile phambi kokuba i-cyanide inxibelelane namasuntswana egolide, kwaye enye igolide ibinokufikeleleka kancinci ngenxa yobukho bezinye iiminerali okanye ukudityaniswa kwamasuntswana.

Uvavanyo lweZalathi zeNkqubo

Ireyithi yoBuyiselo lwegolide

Emva kokulungelelaniswa kwendawo yokongezwa kwe-sodium cyanide, ukuphucuka okubonakalayo kwinqanaba lokubuyisela igolide kuye kwabonwa. Ukudibana ngokuthe ngqo phakathi kwecyanide kunye namasuntswana egolide kukhokelele ekunyibilikeni okupheleleyo kwegolide. Kwinkqubo yangaphambili, izinga lokubuyisela igolide liye laguquguquka malunga ne-[X]%. Nangona kunjalo, ngendlela entsha yokongeza, izinga lokubuyisela liye lonyuka ngokuthe ngcembe laya kutsho malunga ne-[X + Y]%, nto leyo ebonisa ukutsalwa okusebenzayo kwegolide kwintsimbi ekrwada.

Ubunyulu beMveliso yeGolide

Ukongeza kwinqanaba lokubuyisela, ukucoceka kwemveliso yegolide kubonise utshintsho oluhle. Inkqubo ephuculweyo yanciphisa ukutsalwa ngokubambisana kobunye ukungcola, njengoko ukongezwa kwangaphambili kwesodium cyanide kwenze ukuba abantu basabela ngokukhetha ngakumbi ngegolide. Ukusulungeka kwemveliso yokugqibela yegolide kuye kwanda ukusuka [kwipesenti yokusulungeka koqobo] ukuya [kwipesenti entsha yokusulungeka], nto leyo ibaluleke kakhulu ekuphuculeni umgangatho wemveliso yegolide kunye nexabiso layo lemarike.

Uhlalutyo lweeNdleko zoMveliso

Ukusetyenziswa kweSodium Cyanide

Enye yezona zinto zixhalabisayo kwinkqubo ye-cyanidation kukusetyenziswa kwe-sodium cyanide. Okumangalisa kukuba, emva kokulungelelaniswa kwendawo yokongeza, ukusetyenziswa kwe-sodium cyanide yehla. Kwinkqubo yokuqala, ngenxa yokunxibelelana okuncinci kunye namasuntswana egolide, inani elikhulu le-sodium cyanide lalifuneka ukuze kuqinisekiswe ukusabela okwaneleyo. Nangona kunjalo, ngendlela entsha, ukongezwa okujoliswe ngakumbi kwe-sodium cyanide kwakhokelela ekusebenziseni okusebenzayo. Ukusetyenziswa kwe-sodium cyanide ngetoni nganye yeore yehle ukusuka [kwixabiso lokuqala lokusetyenziswa] ukuya [kwixabiso elitsha lokusetyenziswa], okubangele ukongiwa kweendleko.

Ukusetyenziswa kwamandla

Nangona indawo eyongezelelweyo ye-sodium cyanide itshintshile, ukusetyenziswa kwamandla ngokubanzi kwenkqubo akuzange kunyuke. Enyanisweni, ukuya kwinqanaba elithile, ukusetyenziswa kwamandla okuhambelana nokuphazamiseka kwinqanaba lokugqibela lenkqubo lehle kancinci. Oku kungenxa yokuba ukusabela okusebenzayo kwinqanaba langaphambili kunciphise imfuno yokuphazamiseka okugqithileyo kwitanki yokuphazamiseka ukukhuthaza ukusabela phakathi kwecyanide negolide.

Izibonelelo zoqoqosho

Ukonga iindleko

Ukunciphisa ukusetyenziswa kwe-sodium cyanide kukhokelela ngokuthe ngqo ekongeni iindleko. Ukuthathela ingqalelo imveliso enkulu yomgodi wegolide, kwanokuncipha okuncinci kokusetyenziswa kwesodium cyanide ngetoni yentsimbi ekrwada kunokuqokelelana ukuya kutsho kwisixa esikhulu ekuhambeni kwexesha. Ukongeza, ukuhla kancinci kusetyenziso lwamandla nako kube negalelo ekongeni iindleko. Lilonke, ukongiwa kweendleko zenyanga kufikelele [kwixabiso elithile], nto leyo eluphuculo olubonakalayo kulwakhiwo lweendleko zomgodi wegolide.

Ingeniso eyandisiweyo

Izinga eliphezulu lokufunyanwa kwegolide kunye nokuphucuka kokucoceka kwemveliso yegolide kwazisa ingeniso eyandisiweyo. Ngezinga eliphezulu lokubuyisela, igolide eninzi yaveliswa kwisixa esifanayo se-ore. Kwaye ukucoceka okuphuculweyo kuthetha ukuba imveliso yegolide yayinokuthengiswa ngexabiso elingcono kwimarike. Isiphumo esidityanisiweyo sale miba mibini ikhokelele ekwenyukeni okukhulu kwengeniso yenyanga yomgodi wegolide, ifikelele [kwixabiso elithile].

isiphelo

Uhlengahlengiso lwesiza sokongeza i-sodium cyanide kwinkqubo yegolide yecyanidation yesi sityalo sincinci se-CIP se-30 t/d sibonakalise iziphumo ezilungileyo ezimangalisayo. Ngokombono wezalathi zenkqubo, zombini izinga lokubuyiswa kwegolide kunye nokusulungeka kwemveliso yegolide kuphuculwe. Ngokweendleko zokuvelisa, ukusetyenziswa kwe-sodium cyanide kuye kwancipha, kwaye kuye kwancitshiswa kancinane ekusebenziseni amandla. Olu tshintsho ekugqibeleni luguqulelwe kwinzuzo ebalulekileyo yezoqoqosho, kunye nokonga kweendleko kunye nokwanda kwengeniso. Esi senzo sibonelela ngamava axabisekileyo kwezinye imigodi yegolide ngokuqwalasela inkqubo yokuphucula inkqubo ye-cyanidation, kwaye ibonisa ukuba uhlengahlengiso olulula kodwa olucingwe kakuhle kwindawo yokongezwa kwee-reagents eziphambili kunokuba neempembelelo ezintle kakhulu kwimveliso yonke kunye nokusebenza kwezoqoqosho kumgodi wegolide.
