Tšebeliso ea Sodium Cyanide ho Indasteri ea Metallurgical

Selelekela

Sodium cyanide (NaCN), motsoako oa inorganic, o bapala karolo ea bohlokoa ho Indasteri ea metallurgic. Ho sa tsotellehe tlhaho ea eona e chefo haholo, lik'hemik'hale tsa eona tse ikhethang li etsa hore e be ea bohlokoa haholo lits'ebetsong tse 'maloa tsa metallurgic, haholo-holo ha ho ntšoa litšepe tsa bohlokoa. Sengoliloeng sena se kenella lits'ebetsong tse fapaneng tsa Sodium cyanide ho metallurgy, ho hlahloba mekhoa ea eona ea ho sebetsa, melemo, le mathata a 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 Cyanidation: Tšebeliso e tsebahalang haholo ea Sodium cyanide ka metallurgy ke ho ntšoa ha khauta ho tsoa libopeng tsa eona. The Mokhoa oa cyanidation, eo hape e bitsoang MacArthur - Forrest process, e ile ea hlahisoa ho elella bofelong ba lekholo la bo19 la lilemo 'me e ntse e le mokhoa o ka sehloohong oa Khauta e ntšoang lefatshe ka bophara. Ts'ebetsong ena, ore e sithabetseng ea khauta e tšeloa ka tharollo e hlapollang ea sodium cyanide, hangata ka har'a mefuta e fapaneng ea 0.05 - 0.2%. Nakong ea ts'ebetso ena, khauta ea tšepe e kopana le oksijene le sodium cyanide ka tharollo e nang le metsi. Karabelo e fella ka hore khauta e thehe motsoako o qhibilihang o tsejoang e le sodium aurocyanide. Sebaka sena se rarahaneng se ka aroloa ho matrix a ore a setseng. Ka mor'a mohato oa leaching, khauta e tsosolosoa ho tsoa tharollo. Mokhoa o mong o tloaelehileng ke oa ho sebelisa activated carbon, moo khauta - cyanide complex e kenngoeng holim'a carbon (mokhoa o bitsoang carbon - in - pulp kapa CIP). Ka mor'a moo, khauta e ntšoa khabone 'me e hloekisoa ho feta ho fumana khauta e hloekileng.

2. Melemo ea Khauta ho Extraction: Sodium cyanide e ratoa ha ho ntšoa khauta ka mabaka a 'maloa. E sebetsa haholo ho qhaqha khauta esita le ho tloha ho li-ores tsa boemo bo tlaase, tseo hangata e leng tse tloaelehileng merafong ea kajeno. Ts'ebetso e batla e le bonolo ebile e theko e boima - e sebetsa hantle ha e bapisoa le mekhoa e meng. Bokhoni ba eona ba ho etsa li-complexes tse tsitsitseng tse nang le khauta li lumella karohano e ntle ea khauta ho liminerale tse ling tse teng ka har'a ore.

3. Mathata le Matšoenyeho a Tikoloho: Leha ho le joalo, tšebeliso ea sodium cyanide ha ho ntšoa khauta ha e na mathata a eona. Chefo ea eona e feteletseng ke ntho e tšoenyang haholo. Haeba e sa laoloe hantle, sodium cyanide e ka baka tšokelo e kholo bophelong ba batho le tikolohong. Ha ho ka tšolloa kapa ho lutla, cyanide e ka silafatsa mehloli ea metsi, ea bolaea lintho tse phelang metsing. Ho feta moo, ho lahloa ha cyanide - e nang le mehatla, e ntseng e na le cyanide e nyane le lirafshoa tse ling tse boima, ke taba e rarahaneng. Melao e matla ea tikoloho e kentsoe linaheng tse ngata ho netefatsa ts'ebetso e bolokehileng le ho lahloa ha sodium cyanide indastering ea merafo ea khauta.

Monyetla oa Silver

1. Tšoanang Cyanide - Thehiloeng Mekhoa: Sodium cyanide e boetse e sebelisoa ha ho ntšoa silevera ho ores ea eona. Melao-motheo e tšoana le ea ha ho ntšoa khauta. Ores ea silevera e phekoloa ka tharollo ea sodium cyanide, 'me silevera e etsa motsoako oa cyanide o qhibilihang. Sesebelisoa sa silevera - cyanide se ka sebetsoa le ho feta ho fumana silevera e hloekileng. Mekhoa ea ho hlaphoheloa e ka kenyelletsa pula, electrolysis, kapa adsorption mecheng ea litaba e loketseng, e ts'oanang le lits'ebetso tse sebelisetsoang ho khutlisa khauta.

2. Karolo ho Complex Ores: Maemong a mangata, silevera e fumanoa lirapeng tse rarahaneng hammoho le litšepe tse ling tse kang loto, zinki le khauta. Sodium cyanide e ka qhala silevera ka boikhethelo, e lumella ho arohana ha eona le likarolo tse ling. Sena ke sa bohlokoa haholo ho holisa boleng ba ore le ho netefatsa ho ntšoa ha litšepe tsohle tsa bohlokoa ka nepo.

Lisebelisoa ho Metal Plating

1. electroplating: Indasteri ea electroplating, sodium cyanide e sebelisoa ha ho etsoa litšepe tse kang koporo, silevera, cadmium le zinki. Ka bateng ea electroplating ea cyanide, sodium cyanide e sebetsa mesebetsi e mengata. E sebetsa e le ntho e rarahaneng, e thusang ho laola ho kenngoa ha li-ion tsa tšepe holim'a substrate. Ka mohlala, ka electroplating ea koporo, li-ion tsa koporo ka tharollo li etsa li-complexes tse nang le li-ion tsa cyanide. Joale li-ion tse rarahaneng tsa koporo li fokotsoa ka har'a cathode (ntho e lokelang ho petoa) ho etsa depositi ea koporo. Ho ba teng ha cyanide ka bateng ea plating ho ka ntlafatsa boleng ba plating ka ho fokotsa sekhahla sa ho beoa ha tšepe, ho etsa hore ho be le seaparo se ts'oanang le se khomarelang.

2. Melemo ka Plating: Cyanide - based electroplating baths fana ka melemo e mengata. Ba ka fana ka matla a molemo a ho lahlela, e leng se bolelang hore tšepe e kenngoa ka mokhoa o ts'oanang ka lintho tse rarahaneng - tse bōpehileng. Tšebeliso ea sodium cyanide e ka boela ea ntlafatsa khanya le boreleli ba lera le pentiloeng. 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 e seng ea cyanide electroplating. Empa lits'ebetsong tse ling moo ho hlokahalang ho roala boleng ba boleng bo holimo, joalo ka indastering ea mabenyane le lisebelisoa tsa elektroniki, ho ntse ho sebelisoa electroplating ea cyanide e nang le sodium cyanide.

Lisebelisoa tsa ho Hloekisa Metal le ho Hloekisa

1. Ho Tlosa Litšila: Sodium cyanide e ka sebelisoa ho hloekisoa ha litšepe tse itseng ho tlosa litšila. Mohlala, ha ho hloekisoa nickel, cyanide e ka sebelisoa ho khetha litšila tse joalo ka koporo le zinki joalo ka li-complexes tsa cyanide tse fapaneng. Lisebelisoa tsena tsa tšepe - cyanide tsa litšila li ka arohana le tharollo ea nickel ka ho hloekisa kapa mekhoa e meng ea karohano, e lebisang ho sehlahisoa se hloekileng sa nickel.

2. Ho Hloekisa Litšepe Tsa Bohlokoa: Ho hloekisoa ha litšepe tsa bohlokoa tse kang khauta le silevera ka mor'a ho ntšoa, sodium cyanide e ka sebelisoa mehatong e meng ea ho hloekisa. Ka mohlala, e ka sebelisoa ho qhaqha le ho tlosa litšila leha e le life tse setseng tsa tšepe tse neng li sa arohane ka ho feletseng nakong ea ts'ebetso ea pele ea ho ntša. Sena se thusa ho fihlela boemo bo holimo ba bohloeki ba lirafshoa tsa bohlokoa, bo bohlokoa bakeng sa ts'ebeliso ea mabenyane, lisebelisoa tsa elektroniki le merero ea matsete.

Maikutlo a Bokamoso le Mekhoa e Meng

1. Batla Cyanide - Mekhoa e meng ea Mahala: Ka lebaka la chefo le likotsi tsa tikoloho tse amanang le sodium cyanide, ho na le boiteko bo matla ba lipatlisiso ba ho hlahisa mekhoa e meng ea ho ntša le ho sebetsa tšepe. Ka mohlala, indastering ea merafo ea khauta, ho ntse ho etsoa lipatlisiso tse 'maloa tsa li-cyanide - li-leaching agents tse sa lefelloeng, tse kang thiosulfates, halides, le metsoako e itseng ea tlhaho. Mekhoa ena e meng e ikemiselitse ho fana ka ts'ebetso e ts'oanang kapa e betere ea ho ntšoa ntle le likotsi tse amanang le tikoloho le polokeho ea cyanide. Leha ho le joalo, tse ngata tsa mekhoa ena e meng li ntse li le molemong oa liteko kapa tsa pele-pele tsa khoebo 'me li tobana le mathata a kang litšenyehelo tse phahameng, khetho e tlaase, kapa litlhoko tse rarahaneng tsa ho sebetsa.

2. Ntlafatso ea Polokeho le Taolo ea Tikoloho: Khabareng, indasteri ea metallurgic e tsepamisitse maikutlo ho ntlafatsa polokeho le tsamaiso 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 cyanide - e nang le litšila, le tlhahlobo e matlafalitsoeng ho netefatsa hore ho lateloa melao ea tikoloho.
