Tšebeliso ea Sodium Cyanide ho Indasteri ea Metallurgical

Selelekela

Sodium cyanide (NaCN), motsoako o sa pheleng, o bapala karolo ea bohlokoa indastering ea Metallurgical . Ho sa tsotellehe tlhaho ea eona e chefo haholo, litšobotsi tsa eona tse ikhethang tsa lik'hemik'hale li etsa hore e be ea bohlokoa lits'ebetsong tse 'maloa tsa metallurgic, haholo-holo ho ntšoeng ha litšepe tsa bohlokoa. Sengoloa sena se hlahloba lits'ebetso tse fapaneng tsa Sodium cyanide ho metallurgy, se hlahloba mekhoa ea eona ea ho sebetsa, melemo le liphephetso tse amanang le eona.

Lintho tsa Lik'hemik'hale tsa Sodium Cyanide tse Amanang le Metallurgy

Sodium cyanide ke 'mala o mosoeu, o qhibilihang ka metsing. Ka tharollo e nang le metsi, e ikarola ho li-ion tsa sodium (Na⁺) le li-ion tsa cyanide (CN⁻). Ion ea cyanide e bohlokoa haholo ho metallurgy. Ke nucleophile e matla, e bolelang hore e na le kamano e phahameng bakeng sa li-ion tsa tšepe tse qosoang hantle. Thepa ena e lumella li-ion tsa cyanide ho etsa li-complexes tse tsitsitseng tse nang le li-ion tsa tšepe, e leng tšobotsi e sebelisoang lits'ebetsong tse fapaneng tsa metallurgical.

Likopo ho Precious Metal Extraction

Khauta ea Khauta

1. Mokhoa oa ho Hlahisa Kalafo : Tšebeliso e tsebahalang haholo ea Sodium Cyanide ho metallurgy ke ho ntša khauta ho tsoa marong a eona. Mokhoa oa ho Hlahisa Kalafo , o boetse o bitsoa mokhoa oa MacArthur-Forrest, o ile oa ntlafatsoa qetellong ea lekholo la bo19 la lilemo 'me o ntse o le mokhoa o ka sehloohong oa ho ntša Khauta lefatšeng ka bophara. Ts'ebetsong ena, marotholi a khauta a sithabetseng a ntšitsoe ka tharollo e hlapolotsoeng ea sodium cyanide , hangata e le maemong a 0.05 - 0.2%. Nakong ea ts'ebetso ena, khauta ea tšepe e arabela ka oksijene le sodium cyanide ka har'a tharollo ea metsi. Karabelo e fella ka hore khauta e etse motsoako o qhibilihang o tsejoang e le sodium aurocyanide. Motsoako ona o ka aroloa ho tsoa ho matrix e setseng ea marotholi. Kamora mohato oa ho hlahisa, khauta e fumanoa tharollong. Mokhoa o mong o tloaelehileng ke ka tšebeliso ea khabone e sebetsang, moo motsoako oa khauta-cyanide o monngoang ka har'a khabone (ts'ebetso e bitsoang carbon-in-pulp kapa CIP). Ka mor'a moo, khauta e tlosoa khaboneng 'me e hloekisoa ho ea pele ho fumana khauta e hloekileng.

2. Melemo ea ho Ntša Khauta : Sodium cyanide e ratoa haholo ho ntšoeng khauta ka mabaka a 'maloa. E sebetsa hantle haholo ho qhibilihiseng khauta esita le ho tsoa lirafshoeng tsa maemo a tlase, tseo hangata e leng tloaelo merafong ea sejoale-joale. Ts'ebetso ena e bonolo ebile e theko e boima ha e bapisoa le mekhoa e meng e meng. Bokhoni ba eona ba ho theha metsoako e tsitsitseng ka khauta bo lumella karohano e sebetsang ea khauta ho liminerale tse ling tse teng ka har'a lerafshoeng.

3. Liphephetso le Matšoenyeho a Tikoloho : Leha ho le jwalo, tshebediso ya sodium cyanide ho ntsheng kgauta ha e na mathata. Chefo ya yona e feteletseng ke bothata bo boholo. Haeba e sa laolwe hantle, sodium cyanide e ka baka tshoso e kgolo bophelong ba batho le tikolohong. Haeba ho ka tshollwa kapa ha dutla, cyanide e ka silafatsa mehlodi ya metsi, ya bolaya diphedi tsa metsing. Ho feta moo, ho lahla cyanide - e nang le mesaletsa, e ntseng e na le cyanide e nyane le dimethara tse ding tse boima, ke bothata bo rarahaneng. Melao e thata ya tikoloho e se e kentswe dinaheng tse ngata ho netefatsa hore sodium cyanide e tshwarwa ka mokhoa o bolokehileng le ho lahla indasteri ya merafo ya kgauta.

Monyetla oa Silver

1. Mekhoa e Tšoanang e Thehiloeng ho Cyanide : Sodium cyanide e boetse e sebelisoa ho ntšeng silevera ho tsoa marong a eona. Melao-motheo e tšoana le ea ho ntšeng khauta. Marong a silevera a phekoloa ka tharollo ea sodium cyanide, 'me silevera e etsa motsoako oa cyanide o qhibilihang. Motsoako oa silevera-cyanide o ka sebelisoa ho ea pele ho fumana silevera e hloekileng. Mekhoa ea ho hlaphoheloa e ka kenyelletsa pula, electrolysis, kapa ho kenngoa ha metsi mecheng e loketseng, e tšoanang le mekhoa e sebelisoang bakeng sa ho hlaphoheloa khauta.

2. Karolo ho Litšepe tse Rarahaneng : Maemong a mangata, silevera e fumanoa litšepeng tse rarahaneng hammoho le litšepe tse ling tse kang loto, zinki le khauta. Sodium cyanide e ka qhala silevera ka mokhoa o ikhethileng, e leng se lumellang karohano ea eona le likarolo tse ling. Sena se bohlokoa haholo ho holiseng boleng ba letšepe le ho netefatsa ho ntšoa ha litšepe tsohle tsa bohlokoa ka katleho.

Lisebelisoa ho Metal Plating

1. Ho polata ka motlakase : Indastering ea ho polata ka motlakase, sodium cyanide e sebelisoa ho polata ka tšepe tse kang koporo, silevera, cadmium le zinki. Bateng ea ho polata ka motlakase e thehiloeng ho cyanide, sodium cyanide e sebeletsa mesebetsi e mengata. E sebetsa e le moemeli oa ho rarahana, o thusang ho laola ho beoa ha li-ion tsa tšepe holim'a substrate. Mohlala, ho polata ka motlakase ea koporo, li-ion tsa koporo ka har'a tharollo li etsa li-complexes ka li-ion tsa cyanide. Li-ion tsa koporo tse rarahanang lia fokotsoa cathode (ntho e lokelang ho polata) ho etsa depositi ea koporo. Boteng ba cyanide ka bateng ea ho polata bo ka ntlafatsa boleng ba plating ka ho fokotsa sekhahla sa ho beoa ha tšepe, e leng se fellang ka ho koaheloa ho ts'oanang le ho khomarela.

2. Melemo ea ho Sebetsa ka ho Sebetsa ka Matla : Libate tsa ho Sebetsa ka Matla tse thehiloeng ho Cyanide li fana ka melemo e 'maloa. Li ka fana ka matla a betere a ho lahla, ho bolelang hore tšepe e behiloe ka ho lekana linthong tse bōpehileng joaloka tse rarahaneng. Tšebeliso ea sodium cyanide e ka boela ea ntlafatsa khanya le boreledi ba lera le phuthetsoeng. Leha ho le joalo, ka lebaka la chefo ea cyanide, ho na le mokhoa o ntseng o hola oa ho nts'etsapele mekhoa e meng ea ho Sebetsa ka Matla e seng ea Cyanide. Empa lits'ebetsong tse ling moo ho hlokahalang ho Sebetsa ka Matla a Phahameng, joalo ka indastering ea mabenyane le ea elektronike, ho Sebetsa ka Matla ho thehiloeng ho Cyanide ka sodium cyanide ho ntse ho sebelisoa.

Lisebelisoa tsa ho Hloekisa Metal le ho Hloekisa

1. Ho Tlosa Litšila : Sodium cyanide e ka sebelisoa ho hloekiseng litšepe tse itseng ho tlosa litšila. Mohlala, ho hloekiseng nickel, cyanide e ka sebelisoa ho thibela litšila tse kang koporo le zinki e le metsoako ea tsona ea cyanide. Metsoako ena ea tšepe le cyanide ea litšila e ka aroloa ho tsoa tharollong ea nickel ka ho sefa kapa mekhoa e meng ea karohano, e leng se lebisang ho sehlahisoa se hloekileng sa nickel.

2. Ho Hloekisa Tšepe tsa Bohlokoa : Ha ho hloekisoa litšepe tsa bohlokoa tse kang khauta le silevera ka mor'a ho ntšoa, sodium cyanide e ka sebelisoa mehatong e meng ea ho hloekisa. Mohlala, e ka sebelisoa ho qhala le ho tlosa litšila life kapa life tse setseng tsa tšepe ea motheo tse neng li sa aroloa ka botlalo nakong ea ts'ebetso ea pele ea ho ntšoa. Sena se thusa ho fihlela boemo bo phahameng ba bohloeki ba litšepe tsa bohlokoa, e leng sa bohlokoa bakeng sa ts'ebeliso ea mabenyane, lisebelisoa tsa elektroniki le merero ea matsete.

Maikutlo a Bokamoso le Mekhoa e Meng

1. Batla Mekhoa e Meng e sa Lefelloeng ea Cyanide : Ka lebaka la chefo le likotsi tsa tikoloho tse amanang le sodium cyanide, ho na le boiteko bo boholo ba lipatlisiso ho nts'etsapele mekhoa e meng ea ho ntša le ho sebetsana le tšepe. Ka mohlala, indastering ea merafo ea khauta, ho ntse ho fuputsoa lintho tse 'maloa tse ntšang cyanide tse se nang cyanide, tse kang thiosulfates, halides, le metsoako e itseng ea lintho tse phelang. Mekhoa ena e meng e ikemiselitse ho fana ka bokhoni bo tšoanang kapa bo betere ba ho ntša ntle le likotsi tse amanang le tikoloho le polokeho tsa cyanide. Leha ho le joalo, mekhoa ena e mengata e ntse e le mohatong oa liteko kapa oa pele oa khoebo 'me e tobane le liphephetso tse kang litšenyehelo tse phahameng, khetho e tlase, kapa litlhoko tse rarahaneng tsa ts'ebetso.

2. Tsamaiso e Ntlafetseng ea Polokeho le Tikoloho : Ho sa le joalo, indasteri ea tšepe e shebane le ho ntlafatsa polokeho le taolo ea tikoloho ea tšebeliso ea sodium cyanide. Sena se kenyelletsa nts'etsopele ea litsamaiso tse betere tsa ho sebetsana le ho boloka, kalafo e sebetsang hantle ea litšila tse nang le cyanide, le tlhokomelo e ntlafalitsoeng ho netefatsa hore melao ea tikoloho ea lateloa.
