Ochwepheshe Baxoxa Ngendima Ye-Sodium Cyanide Ekukhishweni Kwegolide

Okokuqala, i-cyanide ukukhishwa kwegolide le-sodium, eyaziwa nangokuthi i-cyanide leaching, inqubo eyasungulwa isikhathi eside. Njengamanje, cishe amaphesenti angama-30 egolide emhlabeni akhishwa kusetshenziswa le ndlela, okubonisa ukusetshenziswa kwalo okusabalele.

Izinzuzo: Izindleko eziphansi kanye ne-leaching ephumelelayo.

Ukungalungi: Izinkinga zemvelo.

Eqinisweni, inqubo yendabuko ye-cyanide pool leaching kade yafakwa ohlwini ukuze iqedwe. Namuhla, izindlela eziningi zifaka i-cyanide heap leaching noma i-in-situ leaching, kodwa lezi nazo ziyayekwa kancane kancane, njengoba okwamanje abukho ubuchwepheshe obungcono obungazithatha esikhundleni.

I-sodium cyanide inobuthi obukhulu, ngakho ukuphathwa okuqinile nokulawula kuyadingeka ngaphambi nangemva kokusetshenziswa kwayo.

Ake ngifingqe inqubo yokucutshungulwa kwezimbiwa (noma ukuhlomula). Lesi sihloko singase sibonakale sikude emphakathini, njengoba abantu abaningi bengazi ukuthi ngemva kokumbiwa kwensimbi, kufanele idlule esigabeni sokucubungula izimbiwa. Emehlweni omuntu ovamile, insimbi imane imbiwe bese incibilikiswa ibe insimbi ngokuqondile, akunjalo? Nokho, lo mbono awulungile neze. Ama-ore amaningi ngokuvamile anezinga eliphansi futhi aqukethe ukungcola okuningi, okuwenza angafaneleki ukuncibilika ngokuqondile. Ukwengeza, ukuba khona kokungcola okuningi kwenza inqubo yokuncibilika ibe nzima, kwenyuse izindleko, futhi kubangele imikhiqizo esezingeni eliphansi. Ngakho-ke, kunesinyathelo esidingekayo sokucubungula amaminerali phakathi kwezimayini nokuncibilikisa.

Isibonelo, uma wemba insimbi enensimbi (ibanga) elingu-40%, ukuyincibilikisa ngokuqondile kungaholela ekungcoleni okuyingozi njenge-phosphorus, okwenza insimbi ewumphumela ibe brittle. Yini engenziwa? I-ore ingacutshungulwa ukuze kwenyuswe insimbi ibe ngama-60% ngokusebenzisa izindlela ezinjengokuhlukanisa amandla adonsela phansi, ukuhlukaniswa kazibuthe, kanye nokugaya, okuholela ekugxilweni kwensimbi yebanga lama-60%. Lokhu kugxilisa insimbi kuye kwasuswa ukungcola okuningi futhi kungasetshenziswa ngokuqondile ekuncibilikiseni.

Ngokufanayo, insimbi efana nomthofu, i-zinc, ithusi, i-molybdenum, ne-nickel nayo idinga ukucutshungulwa kwamaminerali anjalo ukuze kugxiliswe amaminerali abalulekile futhi kukhishwe ukungcola, kunikeze izinto zokusetshenziswa ezifanelekayo zokuncibilikisa.

Kusukela kule ncazelo engenhla, umuntu kufanele aqonde isidingo sokucutshungulwa kwezimbiwa. Kuthiwani ngetshe legolide?

Yiqiniso, i-ore yegolide nayo idinga ukucubungula amaminerali.

Ama-ore ajwayelekile e-lead-zinc ngokuvamile anezinga elihlanganisiwe elingaba ngu-5% noma ngaphezulu, kanti amanye ama-ore asezingeni eliphansi angaba ngu-2%. Kodwa-ke, i-ore yegolide ihlukile. Izinga le-ore yegolide lilinganiswa ngamagremu ngethani (g/t). Ama-ore amaningi egolide anamazinga angu-1 g/t noma u-2 g/t kuphela, okusho ukuthi kusukela ethani elilodwa le-ore yegolide, kungaba khona igremu eli-1 noma amagremu amabili egolide kuphela. Leli golide likhishwa kanjani? Ngokuvamile kwenziwa kusetshenziswa i-cyanide, encibilikisa igolide ku-ore, bese isebenza. I-Carbon isetshenziselwa ukumunca nokukhipha igolide, okuholela odakeni lwegolide olungacwengwa lube yizingodo zegolide. Inqubo ye-cyanide okwamanje iyindlela engabizi kakhulu futhi engabizi kakhulu.

Ingabe ikhona enye into engancibilikisa igolide futhi ithathe indawo ye-cyanide?

Eqinisweni, kunezinto eziningi ezingancibilikisa igolide, kodwa ukuthola enye indlela engokoqobo I-sodium cyanide kuyinselele impela.

I-Thiourea ingancibilikisa igolide, kodwa isilinganiso esidingekayo sikhulu kakhulu, okwenza sibize kakhulu!

I-Polysulfides ne-lime sulfur nayo ingasetshenziswa, kodwa idinga ama-ion ammonia e-copper, futhi umthamo uphakeme ngendlela efanayo, okuholela ezindlekweni eziphezulu.

Zikhona futhi izindlela ze-biological leaching, kodwa lezi zisesigabeni sokuhlola.

Ezinye izindlela ezisetshenziswa kakhulu ama-ejenti amasha okukhipha amanzi afana ne-JINCHAN ne-JINFU. Ukuthi lawa ma-ejenti aqukethe i-cyanide kuyaphikiswana ngawo, futhi ukusebenza kwawo ngempumelelo nakho kuyindaba yokuxoxa. Ezinye izimayini seziwasebenzisile ngemiphumela ehloniphekile, kodwa ukukhushulwa kwenani elikhulu noma ngethemba lokuthi zingasebenza emhlabeni wonke I-Sodium Cyanide ngoba izimayini eziningi zegolide kusenzima impela.

Ngakho-ke, inqubo ye-cyanide ihlala iyindlela evamile.

Ama-ejenti angena-cyanide asebenzisa i-cyanide noma izinqubo ezisungulwe abacwaningi ekucutshungulweni kwezimbiwa zibhekana nezinselele ezinkulu ekukhuthazeni nasekusekelweni okuvela eminyangweni efanele, okwenza kube nzima ukuzisebenzisa kabanzi. Phela labo abasembonini bayakwazi lokho i-sodium cyanide iyasebenza, kulula ukuyisebenzisa, futhi iyonga—ubani ongeke afune ukukhulisa inzuzo?

Ukuze ungene esikhundleni senqubo ye-cyanide, kunzima ngaphandle kokusekelwa okuqinile kukazwelonke kokuphromotha noma uxhaso lwezimali zocwaningo oluhlobene.

Ingabe kuyiqiniso ukuthi izinqubo ze-cyanidation, njengoba zivamile, kufanele zilimaze imvelo?

Amazwe anezinqubomgomo ezihlukahlukene zokuvikela imvelo, futhi kunezindlela eziqinile zokwelashwa kanye nemithethonqubo yamanzi angcolile ezimayini, izisombululo zokuvuza, nezinsalela zemfucuza.

Eqinisweni, ingaba yingozi kangakanani i-sodium cyanide? Kuyiqiniso ukuthi ukulidla kungaba yingozi. Nokho, ingelashwa; ngokungeza i-bleaching powder, ingabola ngokusabela kwe-redox. Amazwe amaningi anezinqubomgomo ezihambisanayo, iziqondiso, kanye namazinga okulawula lolu daba.

Ukuze uthole iziphakamiso zochwepheshe ezengeziwe? Xhumana nathi!
