Tšebeliso ea Sodium Cyanide ho Indasteri ea Metallurgical le Ho arolelana Boiphihlelo

Selelekela

Sodium cyanide (NaCN), e le moemeli ea sebetsang hantle oa ho kopanya le ho ntša metsi, e bapala karolo ea bohlokoa Indastering ea Metallurgical . Litšobotsi tsa eona tse ikhethang tsa lik'hemik'hale li e nolofalletsa ho theha metsoako e tsitsitseng e nang le li-ion tse fapaneng tsa tšepe, ka hona e fihlella ho ntšoa, ho aroloa le ho hloekisoa ha litšepe. Sengoloa sena se tla sekaseka lits'ebetso tsa mantlha tsa Sodium Cyanide tšimong ea metallurgic le ho akaretsa lintlha tsa bohlokoa tsa ts'ebetso ho latela boiphihlelo bo sebetsang.

I. Tšebeliso ea Core ea Sodium Cyanide ho Indasteri ea Metallurgis

1.Tlhahiso ea Khauta (Cyanidation Process for Gold Extraction)

• Molao-motheo : Sodium cyanide e arabela le khauta moo oksijene e leng teng ho etsa metsoako ea cyanide ea khauta e qhibilihang (joalo ka [Au(CN)₂]⁻). Khauta e ntan'o fumanoa ka ho kenngoa ha khabone e sebetsang kapa ho fallisoa ha zinki.

• Melemo : E na le bokgoni bo matla ba ho ikamahanya le diminerale tsa kgauta tsa maemo a tlase le diminerale tse rarahaneng, mme sekgahla sa ho dutla ha leifo se ka fihla ho feta 90%.

• Nyeoe : Morafo oa khauta o ekelitse sekhahla sa ho hlaphoheloa ha khauta ho 92% ka ho ntlafatsa mahloriso a sodium cyanide (0.05%-0.1%) le nako ea ho ntša metsi (lihora tse 24-48).

2.Electroplating le Metal Surface Treatment

• Morero : Jwalo ka sehlomathiso ditharollong tsa Electroplating , e sebediswa bakeng sa ho electroplating ditshipi tse kang koporo, zinki le silevera, tse ka ntlafatsang ho tshwana le ho kgomarela ha seaparo.

• Litlhokomelo : Ho bokellana ha cyanide ho hloka ho laoloa ka thata ho qoba masalla a mangata, a ka lebisang tšilafalong ea tikoloho.

3.Metal karohano le tlhoekiso

• Maemo a Tšebeliso : Khetha litšepe tse reriloeng (tse kang nickel le cobalt) ho tsoa litšepeng tsa polymetallic, kapa u tlose li-ion tse litšila (tse kang tšepe le loto).

• Lintlha tsa Tekheniki : Finyella ho kopana ha litšepe tse fapaneng ka mohato ka mohato ka ho fetola boleng ba pH le tekanyo ea Sodium cyanide.

II. Boiphihlelo ba Bohlokoa le Ntlafatso ea Setsebi Tšebelisong ea Sodium Cyanide

1.Taolo ea Boiketlo le Tekanyetso

• Molao oa Matla : Nakong ea ho ntša khauta, khatello ea sodium cyanide hangata ke 0.03%-0.1%, 'me e hloka ho fetoloa ho latela thepa ea lejoe (joalo ka litaba tsa khabone le litaba tsa sulfide).

• Nyeoe : Moepo o fumane hore tšebeliso ea sodium cyanide e eketsehile ka mokhoa o sa tloaelehang. Kamora lipatlisiso, ho fumanoe hore sebabole se ka har'a lejoe se feta tekanyetso. Bothata bo rarollotsoe kamora ho sebelisa mokhoa oa pele oa kalafo (ho besa kapa ho oxidation).

2.Optimization of Leaching Conditions

• Boleng ba pH : Ho boloka tikoloho e nang le alkaline (pH 10-11) ho ka thibela tlhahiso ea khase ea hydrogen cyanide le ho ntlafatsa Bokhoni ba ho Lutla ha Leaching ka nako e le 'ngoe.

• Mocheso : Ho futhumatsa ho loketseng (30-40°C) ho ka potlakisa karabelo, empa tshebediso ya matla le ditjeo di hloka ho leka-lekana.

3.Tshireletso ea Tikoloho le Taolo ea Polokeho

• Kalafo ea Metsi a Litšila : Sebelisa mokhoa oa alkaline chlorination (sodium hypochlorite + sodium hydroxide) ho qhala cyanide ho netefatsa hore ho ntšoa ha metsi ho fihlela tekanyetso (khatello ea CN⁻ e ka tlase ho 0.5 mg/L).

• Tšireletso ea Polokeho : Hlomella ka mohala oa tlhahiso o koetsoeng ka botlalo, sistimi ea ho beha leihlo e iketsang, le sesebelisoa sa ho fafatsa ka tšohanyetso. Basebetsi ba lokela ho apara liaparo tse sireletsang tsa lik'hemik'hale le limaske tsa khase.

III. Mathata a Tloaelehileng le Litharollo

1.Kotsi ea Chefo ea Cyanide

• Mehato ea Thibelo : Kamehla hlahloba ho tiea ha lisebelisoa 'me u qobe ho kopana ha tharollo ea cyanide le lintho tse nang le asiti (ho thibela tlhahiso ea khase e chefo haholo ea HCN).

• Kalafo ea Tšohanyetso : Hlatsoa hang-hang sebaka seo letlalo le kopanang le sona ka metsi a mangata a hloekileng. Haeba motho a ka monya ka phoso, motho ea hlokofalitsoeng o lokela ho batla phekolo hang-hang 'me a entoe ka sodium thiosulfate bakeng sa ho ntša chefo letlalong.

2.Decrease in Leaching Effective

• Mabaka a ka bang teng : Tekanyo e sa lekaneng ea oxidation ea lejoe, ho bola ha sodium cyanide (ka lebaka la khanya kapa mocheso o phahameng), le tšitiso ea li-ion tse sa hloekang (tse kang loto le koporo).

• Litharollo : Kenya oxidant (joalo ka hydrogen peroxide) ho kgothaletsa oxidation ya lejwe, kapa ho tlosa ditshila ka ho di phekola pele ho nako.

IV. Mekhoa ea Bokamoso le Mahlale a Mang

• Mekhoa ea ho Lutla Ha e na Cyanide : Mekhoa e metle joalo ka mokhoa oa thiourea le mokhoa oa bioleaching e ntse e hlaha butle-butle, e leng se ka fokotsang likotsi tsa tikoloho.

• Taolo e Bohlale : Ho beha leihlo diparamente ka nako ya sebele tse kang mahloriso a sodium cyanide le boleng ba pH ka di-algorithms tsa AI ho fihlella taolo e nepahetseng.

fihlela qeto e

Sodium cyanide e na le bokgoni bo phahameng le dikotsi tse ka bang teng indastering ya metallurgical. Tshebediso e utlwahalang e itshetlehile hodima moralo wa tshebetso ya saense, taolo e tiileng ya polokeho, le boqapi bo tswelang pele ba theknoloji. Ka ho ntlafatsa diparamitha tsa tshebetso le ho matlafatsa mehato ya Tshireletso ya Tikoloho , boleng ba yona bo ka eketswa mme dikotsi tsa fokotseha, ho kgothaletsa indasteri ho ntshetsa pele ka tsela e tala le e tsitsitseng.
