Izinzuzo Eziyinhloko Ze-Sodium Cyanide Heap Leaching Yokukhipha Igolide

Sodium i-cyanide i-heap leaching iyindlela esetshenziswa kakhulu embonini yezimayini zegolide yokukhipha igolide kuma-ore asezingeni eliphansi. Le nqubo ihlanganisa ukunqwabelanisa insimbi yegolide yezinga eliphansi noma izinsalela ezintantayo empahleni yephedi nokufafaza isixazululo secyanide phezu kwenqwaba ukuze kuncibilike igolide nesiliva, kwakheka isixazululo esinegolide ukuze siphinde sitholakale. Nazi izinzuzo eziyinhloko zale nqubo:

Izindleko - ukusebenza kahle

1.Ukutshalwa kwezimali okuphansi: Enye yezinzuzo ezibaluleke kakhulu ze I-sodium cyanide i-heap leaching iyisidingo sayo semali ephansi uma kuqhathaniswa. Uma kuqhathaniswa nezindlela eziyinkimbinkimbi zokukhipha igolide njengokugaya nokuncibilikisa okungokwesiko, okudinga ingqalasizinda eningi kanye nemishini, inqwaba yokufakwa kwemfucuza idinga kuphela izinsiza eziyisisekelo ezifana nephedi le-leaching, uhlelo lokuqoqa izixazululo, kanye nezindlela zokusatshalaliswa kwezixazululo. Asikho isidingo sokwakha izindawo zokucubungula ezinkulu nezimba eqolo, okwenza kube yindlela ekhangayo, ikakhulukazi emisebenzini yezimayini emincane ukuya kwephakathi noma yamadiphozithi ezimayini anezinsiza ezilinganiselwe.

2.Ukwehliswa kwezindleko zokusebenza:

• Ukusetshenziswa kwamandla aphansi: Inqubo ye-heap leaching inesidingo esiphansi samandla. Akubandakanyi ukusebenza okunamandla okunamandla njengokugaya ama-ore abe yimpushana emshinini wokugaya ibhola, okuvamile kwezinye izindlela zokukhipha. Ukusebenza okulula kokufafaza kwesixazululo kanye nokubhoboza ngenqwaba yensimbi kudinga amandla amancane kakhulu, okuholela ekwehleni kwezindleko zamandla.

• Izindleko eziphansi ze-reagent (ngokuhlobene nezinye izindlela): Nakuba i-cyanide iyisisetshenziswa esibalulekile futhi ukuphatha kwayo kudinga izinyathelo zokuphepha eziqinile, ngokuya ngayo yonke inqubo yokukhipha igolide, inani le-cyanide elidingekayo ukuze kukhishwe inqwaba lingathuthukiswa. Uma kuqhathaniswa namanye ama-ejenti okuchetshwa kwegolide ekukhishweni kwegolide, i-cyanide ingaba yindleko - isebenze kahle ezimweni ezithile, ikakhulukazi uma kucatshangelwa umthamo omkhulu we-ores wezinga eliphansi ongacutshungulwa kusetshenziswa le ndlela.

Ukufaneleka kwensimbi yezinga eliphansi

1. Ukukhishwa kwezomnotho kumadiphozithi ebanga eliphansi: I-sodium cyanide heap leaching ifaneleka kakhulu - ilungele ukwelapha ama-ores egolide ebanga eliphansi, ngokuvamile lawo anamabanga asukela ku-0.5 - 3g/t. Lokhu kukhulise kakhulu izinsiza zegolide ezisebenza ngokwezomnotho. Esikhathini esedlule, idiphozithi eminingi yezinga eliphansi yayibhekwa njengengenamali kweyami. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe be-heap leaching, lawa madiphozithi manje angasetshenziswa ngokunenzuzo. Isibonelo, kwezinye izifunda lapho amadiphozithi egolide ngesilinganiso esikhulu, esezingeni eliphezulu eyivelakancane, ukumbiwa kwegolide ezinsimbini zezinga eliphansi ngokusebenzisa inqwaba yokucwiliswa kwegolide sekuphenduke umthombo omkhulu wokukhiqizwa kwegolide.

2. Ukusetshenziswa kwezinsiza ebezingakaze zisetshenziswe ngaphambilini: Ivumela ukusetshenziswa kwezinhlobo ezahlukene zezinsiza ebezingasetshenziswa ngaphambilini, ezifana nemfucumfucu yasezimayini, okuhlanganisa nezinsalela zemisebenzi yokumba yangaphambilini kanye nensimbi yezinga eliphansi eyayishiywe ngesikhathi kuqhubeka inqubo yokumba. Ngokucubungula lezi zinto, akugcini nje ukutholwa igolide elengeziwe, kodwa futhi kusiza ekwehliseni umkhondo wemvelo ohambisana nokugcina inani elikhulu lezinto ezilahlwayo.

Inqubo ibe lula

1. Ukusebenza kalula: Inqubo yokukhishwa kwenqwaba iqondile ekusebenzeni kwayo. Uma inqwaba yensimbi seyakhiwe endaweni elungiselelwe kahle yokuleaching, umsebenzi omkhulu uhilela ukufafaza ingxube ye-cyanide phezu kwenqwaba. Inqubo ayidingi abasebenzi abanamakhono aphezulu emisebenzini yansuku zonke. Abasebenzi bangaqeqeshwa ngokushesha ukuze benze imisebenzi efana nokufafaza ngesixazululo, ukuqapha amazinga okugeleza kwezixazululo, nokuqoqa amasampula. Lokhu kulula futhi kunomthelela ekwehleni kwezindleko zabasebenzi ezihambisana nokuqeqeshwa nokuqasha abasebenzi abakhethekile kakhulu.

2.Izinyathelo ezimbalwa zokucubungula: Uma kuqhathaniswa nezinqubo zokukhipha igolide eziyinkimbinkimbi, i-heap leaching inezinyathelo ezimbalwa zokucubungula. Asikho isidingo sezinqubo zokuhlukanisa amaminerali eziyinkimbinkimbi ezifana ne-froth flotation, okubandakanya izinyathelo eziningi zokwengeza ama-reagents ahlukene ukuhlukanisa amaminerali anegolide namaminerali e-ganggue. Lapho kucwiliswa inqwaba, isixazululo se-cyanide sithintana ngokuqondile ne-ore enqwabeni, sincibilikisa igolide nesiliva, senze inqubo yokukhipha ibe lula.

Intuthuko yezobuchwepheshe ithuthukisa ukusebenza kahle

1.Izindlela ezithuthukisiwe ze-agglomeration: Ukuthuthukiswa kwezindlela ezithuthukisiwe ze-agglomeration kuthuthukise kakhulu ukusebenza kahle kwe Ukukhishwa kwe-sodium cyanide heap. Kuma-ores angakwazi ukungena kahle noma okuqukethwe kobumba oluphezulu, i-agglomeration ingasetshenziswa ukuthuthukisa ukugeleza kwesisombululo se-cyanide ngenqwaba ye-ore. Ngokungeza izibophezelo ezifana ne-lime noma usimende we-Portland ensimbini bese umanzisa futhi uhlanganise ingxube ngomshini, ukwakheka kwamashaneli okukhishwa kwesixazululo kuyakhuthazwa. Lokhu kubangela ukuthintana okuphumelelayo phakathi kwesixazululo se-cyanide namaminerali anegolide, okuholela ekwenyukeni kwamazinga okuthola igolide.

2. Ukusetshenziswa kwezithasiselo ukuthuthukisa ukuvuza: Ukwengezwa kwezithasiselo ezithile kungathuthukisa kakhulu inqubo yokucwilisa. Isibonelo, ukusetshenziswa kwama-oxygen - akhipha ama-oxygen afana ne-oxygen emsulwa noma i-calcium peroxide kungakhuphula amandla okukhipha i-oxidation ekhambi le-leaching, kuthuthukise ukuncibilika kwegolide. Ukwengeza, ama-agent asebenzayo angengezwa ukuze kuthuthukiswe ukumanziswa kwezinhlayiya ze-ore ngesisombululo se-cyanide, ukuthuthukisa ukusebenza kahle kokucwiliswa kwe-ore. Lokhu kuthuthuka kwezobuchwepheshe kwenziwe I-Sodium Cyanide i-heap leaching isebenza kahle kakhulu futhi isebenza ngempumelelo ekukhipheni igolide ezinhlotsheni ezahlukahlukene zamatshe.
