Izinzuzo Eziyinhloko Ze-Sodium Cyanide Heap Leaching Yokukhipha Igolide

I-Sodium cyanide heap leaching iyindlela esetshenziswa kabanzi embonini yezimayini zegolide yokukhipha igolide kuma-ore asezingeni eliphansi. Le nqubo ihilela ukufaka ama-ore egolide asezingeni eliphansi noma ama-flotation tailings entweni yephedi bese ufafaza isixazululo se-cyanide phezu kwenqwaba ukuze kuncibilikiswe igolide nesiliva, kwakhiwe ikhambi eliphethe igolide ukuze kutholakale kabusha okulandelayo. Nazi izinzuzo eziyinhloko zale ndlela:

Izindleko - ukusebenza kahle

1. Ukutshalwa kwezimali okuphansi: Enye yezinzuzo ezibaluleke kakhulu ze- Sodium cyanide heap leaching isidingo sayo semali esincane kakhulu. Uma kuqhathaniswa nezindlela zokukhipha igolide eziyinkimbinkimbi njengokugaya nokuncibilikisa kwendabuko, ezidinga ingqalasizinda enkulu kanye nemishini, i-heap leaching idinga kuphela izinsiza eziyisisekelo njenge-leaching pad, uhlelo lokuqoqa izixazululo, kanye nendlela yokujikeleza kwezixazululo. Asikho isidingo sokwakha izitshalo zokucubungula ezinkulu nezibizayo, okwenza kube inketho ekhangayo, ikakhulukazi emisebenzini yokumba encane kuya kwephakathi noma kumadiphozithi okumba anezinsiza ezilinganiselwe.

2.Ukwehliswa kwezindleko zokusebenza:

• Ukusetshenziswa kwamandla aphansi: Inqubo yokususa inqwaba inesidingo samandla esiphansi. Ayibandakanyi imisebenzi enamandla amakhulu njengokugaya ama-ore abe yimpuphu ecolekileyo emshinini wokugaya ibhola, okuyinto evamile kwezinye izindlela zokukhipha. Ukusebenza okulula kokufutha isixazululo kanye nokubhoboza inqwaba ye-ore kudinga amandla amancane kakhulu, okuholela ekwehliseni izindleko zamandla.

• Izindleko eziphansi ze-reagent (uma kuqhathaniswa nezinye izindlela): Nakuba i-cyanide iyi-reagent ebalulekile futhi ukuphathwa kwayo kudinga izinyathelo zokuphepha eziqinile, ngokwenqubo yokukhipha igolide iyonke, inani le-cyanide elidingekayo ekukhucululeni igolide lingalungiswa. Uma kuqhathaniswa nezinye izindlela zokukhipha igolide, i-cyanide ingabiza kakhulu ezimweni ezithile, ikakhulukazi uma ucabangela inani elikhulu lama-ore aphansi angacutshungulwa kusetshenziswa le ndlela.

Ukufaneleka kwensimbi yezinga eliphansi

1. Ukukhishwa ngokwezomnotho kusuka kuma-depositi ebanga eliphansi: Ukukhishwa kwe-sodium cyanide heap leaching kufaneleka kakhulu ekwelapheni ama-ore egolide ebanga eliphansi, ngokuvamile lawo anamazinga asukela ku-0.5 - 3g/t. Lokhu kuye kwandisa kakhulu ububanzi bemithombo yegolide ephumelelayo ngokwezomnotho. Esikhathini esidlule, ama-depositi amaningi ebanga eliphansi ayebhekwa njengangafanele ukumbiwa. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe bokukhishwa kwe-heap, la ma-depositi manje angasetshenziswa ngenzuzo. Isibonelo, kwezinye izindawo lapho ama-depositi egolide amakhulu, ebanga eliphezulu enqabile khona, ukukhishwa kwegolide kuma-ore ebanga eliphansi ngokusebenzisa i-heap leaching sekuwumthombo omkhulu wokukhiqizwa kwegolide.

2. Ukusetshenziswa kwezinsizakusebenza ezazingasetshenziswanga ngaphambilini: Kuvumela ukusetshenziswa kwezinhlobo ezahlukene zezinsizakusebenza ezazingasetshenziswanga ngaphambilini, njengezinto ezilahliwe zokumba, okuhlanganisa imfucuza evela emisebenzini yokumba ngaphambilini kanye nezinsimbi ezisezingeni eliphansi ezashiywa ngesikhathi senqubo yokumba. Ngokucubungula lezi zinto, igolide elengeziwe alikwazi ukutholwa kuphela, kodwa futhi kusiza ekunciphiseni umonakalo wemvelo ohlobene nokugcina inani elikhulu lezinto ezilahliwe.

Inqubo ibe lula

1. Ukulula kokusebenza: Inqubo yokukhipha inqwaba ilula kakhulu ekusebenzeni kwayo. Uma inqwaba yetshe lensimbi yakhiwe phezu kwephedi yokukhipha insimbi elungiselelwe kahle, umsebenzi oyinhloko uhilela ukufafaza njalo isixazululo se-cyanide phezu kwenqwaba. Le nqubo ayidingi abasebenzi abanamakhono aphezulu emisebenzini yansuku zonke. Izisebenzi zingaqeqeshwa ngokushesha ukuze zenze imisebenzi efana nokufutha isixazululo, ukuqapha amazinga okugeleza kwesisombululo, kanye nokuqoqa amasampula. Lokhu kulula futhi kunegalelo ekunciphiseni izindleko zabasebenzi ezihlobene nokuqeqeshwa kanye nokuqasha abasebenzi abangochwepheshe kakhulu.

2. Izinyathelo zokucubungula ezimbalwa: Uma kuqhathaniswa nezinqubo zokukhipha igolide eziyinkimbinkimbi kakhulu, ukukhipha inqwaba kunezinyathelo ezimbalwa zokucubungula. Asikho isidingo sezinqubo zokuhlukanisa amaminerali eziyinkimbinkimbi ezifana nokugeleza kwegwebu, okubandakanya izinyathelo eziningi zokwengeza ama-reagent ahlukene ukuze kuhlukaniswe amaminerali aphethe igolide kumaminerali e-gangue. Ekukhipheni inqwaba, isixazululo se-cyanide sithinta ngqo i-ore enqwabeni, sincibilikise igolide nesiliva, okwenza kube lula inqubo yokukhipha iyonke.

Intuthuko yezobuchwepheshe ithuthukisa ukusebenza kahle

1. Amasu okuhlanganisa athuthukisiwe: Ukuthuthukiswa kwamasu okuhlanganisa athuthukisiwe kuthuthukise kakhulu ukusebenza kahle kwe -Sodium cyanide heap leaching . Kuma-ore anokungena okuncane noma okuqukethwe okuphezulu kobumba, i-agglomeration ingasetshenziswa ukuthuthukisa ukugeleza kwesisombululo se-cyanide ngenqwaba ye-ore. Ngokufaka ama-binders afana ne-lime noma i-Portland cement ku-ore bese kumanziswa futhi kuhlanganiswe ngomshini ingxube, ukwakheka kweziteshi zokuxuba isixazululo kuyakhuthazwa. Lokhu kuphumela ekuthinteni okuphumelelayo phakathi kwesisombululo se-cyanide namaminerali aphethe igolide, okuholela ekwandeni kwamazinga okubuyisa igolide.

2. Ukusetshenziswa kwezithasiselo ukuthuthukisa ukucwiliswa kwe-ore: Ukwengezwa kwezithasiselo ezithile kungathuthukisa kakhulu inqubo yokucwiliswa kwe-ore. Isibonelo, ukusetshenziswa kwezinto ezikhipha umoya-mpilo njenge-oxygen emsulwa noma i-calcium peroxide kungandisa amandla okucwiliswa kwesisombululo sokucwiliswa kwe-ore, kuthuthukise ukuncibilika kwegolide. Ngaphezu kwalokho, izinto ezisebenzayo ezingaphezulu zingangezwa ukuze kuthuthukiswe ukumanziswa kwezinhlayiya ze-ore yisisombululo se-cyanide, kuthuthukiswe ukusebenza kahle kokucwiliswa kwe-ore. Lokhu kuthuthuka kwezobuchwepheshe kwenze ukucwiliswa kwe -Sodium Cyanide heap kusebenze kahle futhi kuphumelele kakhulu ekukhipheni igolide ezinhlotsheni ezahlukene ze-ore.
