Bohlokoa ba Sodium Cyanide Merafong

Khauta le Silevera

Tšebeliso ea bohlokoa ka ho fetisisa ea sodium cyanide merafong ke ts'ebetsong ea cyanidation bakeng sa ho ntšoa ha khauta le silevera. Khauta le silevera hangata li hlaha lirafshoeng tse tlaase, 'me cyanide e etsa motsoako o qhibilihang ka litšepe tsena tsa bohlokoa. Ha ho na le oksijene le metsi, Sodium cyanide e arabela le khauta kapa silevera ka har'a lerōle, e etsa ion e rarahaneng ea tšepe - cyanide, joalo ka [Au(CN)₂]⁻ kapa [Ag(CN)₂]⁻. Motsoako ona o ka aroloa habonolo ho tloha ho matrix ea lerōle, hangata ka mokhoa oa ho monya khabone e sebetsang kapa ka ho sebelisa mekhoa e meng ea lik'hemik'hale bakeng sa tlhoekiso e eketsehileng.

Litšenyehelo - katleho

Ha ho bapisoa le mekhoa e meng ea ho ntša, ts'ebetso ea cyanidation e sebelisang sodium cyanide e batla e le litšenyehelo - e sebetsa hantle. E lumella ho ntšoa ha litšepe tsa bohlokoa mefuteng e mengata ea ore, ho kenyelletsa le tse nang le mineralogy e rarahaneng. Ts'ebetso ena ea litšenyehelo e etsa hore ho khonehe hore lik'hamphani tsa merafo li sebetse ka mokhoa o nang le phaello, haholo-holo ha li sebetsana le mesebetsi e meholo ea merafo moo ho ka fihlelloang moruo oa tekanyo.

Ha e sebelisoa hantle, mokhoa oa cyanidation o ka finyella litekanyetso tse phahameng tsa ho hlaphoheloa tsa khauta le silevera. Ka ho ntlafatsa maemo a kang pH, cyanide concentration, le ho fumaneha ha oksijene, lik'hamphani tsa merafo li ka ntša karolo e kholo ea lirafshoa tsa bohlokoa tse teng ka har'a ore. Litefiso tse phahameng tsa ho hlaphoheloa ha li eke feela phaello ea mosebetsi oa merafo empa hape li kenya letsoho tšebelisong e ntle ea lisebelisoa tsa tlhaho tse fokolang.

Sodium cyanide e lokela ho bolokoa libakeng tsa polokelo tse inehetseng, tse hlophisitsoeng hantle. Mehaho ena e lokela ho hahuoa ka thepa e hananang le kutu ka tharollo ea cyanide. Li boetse li lokela ho behoa libakeng tse hole le libaka tsa bolulo, mehloli ea metsi le libakeng tse ling tse hlokolosi.

Koetliso le Polokeho ea Basebetsi

Basebetsi bohle ba amehang ho sebetsanang le sodium cyanide ba tlameha ho fumana koetliso e felletseng ea polokeho. Koetliso ena e lokela ho akaretsa thepa ea sodium cyanide, ho kenyelletsa le chefo ea eona, mokhoa oa ho sebetsana ka mokhoa o sireletsehileng le ho fetisetsa litharollo tsa cyanide, le tšebeliso e nepahetseng ea thepa ea ho itšireletsa (PPE).
