Papiso pakeng tsa Sodium Cyanide le Li-Leaching Agents tse Boloketseng Tikoloho ka 2026

1. Nalane ea Indasteri ka 2026

Theknoloji ea ho ntša khauta ka 2026 e eme sebakeng se pakeng tsa khōlo ea indasteri 'me phetoho ea tikoloho. Sodium cyanide (NaCN) e ntse e le eona e sebelisoang haholo Sesebediswa sa ho Leaching sa Khauta lefatšeng ka bophara ka lebaka la bokgoni ba yona ba botekgeniki bo sa bapisweng le letho le melemo ya moruo. Ka nako e ts'oanang, di-agent tsa ho tlosa leaching tse mosa tikolohong, tse atisang ho bapatswa e le "tse se nang cyanide" kapa "di-agent tsa ho tlosa leaching tse tala," di ntse di tswela pele ho hapa tlhokomelo tlasa melao e ntseng e eketseha ya tikoloho le meralo ya matsete e tsamaiswang ke ESG.

Ho ena le kamano e bonolo ea ho nkela sebaka, 'nete ea indasteri ea hona joale e bontša ho phela hammoho le ho arohana Pakeng tsa Sodium cyanide le mekhoa e meng ea ho ntša metsi, e 'ngoe le e 'ngoe e sebeletsa mefuta e fapaneng ea tšepe, libaka tsa taolo le lipheo tsa ts'ebetso.

2. Melao-motheo ea Lik'hemik'hale le ea Botekgeniki

2.1 Mokhoa oa ho Ntša Sodium Cyanide

Sodium cyanide e qhala khauta ka karabelo e thehiloeng hantle ea Elsner:

4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH

Litšobotsi tsa bohlokoa tsa tekheniki:

• Khetho e phahameng bakeng sa khauta le silevera

• Ho lumellana ho pakiloeng le litsamaiso tsa CIP/CIL le heap leaching

• Kinetics e ka boleloang esale pele le taolo e tsitsitseng ea ts'ebetso

• Lintlha tse ngata tsa indasteri tse bokelletsoeng ka lilemo tse fetang 130

2.2 Mekhoa ea Lisebelisoa tsa ho Lutla tse Sireletsang Tikoloho

Disebediswa tsa ho ntsha metsi tse sireletsang tikoloho di kenyeletsa ditsamaiso tse thehilweng ho thiosulfate, ditsamaiso tse thehilweng ho glycine, ditsamaiso tsa chloride, le di-reagent tse ikgethileng tsa metswako. Mekgwa ya tsona e a fapana, empa ka kakaretso e itshetlehile ka:

• Ho rarahana ha khauta tlas'a maemo a bonolo a alkaline kapa a sa nke lehlakore

• Chefo e fokotsehileng e matla ha e bapisoa le cyanide

• K'hemistri e rarahaneng haholoanyane ea reagent le kutloisiso ea ts'ebetso

Leha litsamaiso tse ngata tse mosa tikolohong li khahla, li ntse li haelloa ke mehlala e tloaelehileng ea indasteri ho pholletsa le 'mele e fapaneng ea tšepe.

3. Bokgoni ba ho Ntša Metsi le Sekgahla sa ho Atlehisa Metsi

Ka 2026, sodium cyanide e ntse e le tekanyetso bakeng sa lits'ebetso tse kholo le tse matla tsa ho hlaphoheloa, haholo-holo bakeng sa majwe a boleng bo tlase le a sa hanyetseng kamora kalafo pele ho nako. Dintho tse sireletsang tikoloho hangata di sebetsa hantle li-ore tsa oxide tse phahameng kapa tse bonolo, empa ho tsitsa ha ho hlaphoheloa ho fapana haholo.

4. Papiso ea Sebopeho sa Litšenyehelo

4.1 Sodium cyanide

• Litšenyehelo tse tlase tsa reagent ka thane ea ore

• Ketane ea phepelo ea lefats'e e holileng

• Litefiso tsa tšebeliso tse ka boleloang esale pele

• CAPEX e tlase ka lebaka la lisebelisoa tse tloaelehileng

4.2 Baemeli ba ho Lutla ba Sireletsang Tikoloho

• Litšenyehelo tse phahameng tsa reagent ea yuniti

• Hangata litefiso tse phahameng tsa tšebeliso

• Ho hlokahala litsamaiso tse ling tsa taolo

• Keketseho ea OPEX ka lebaka la ho rarahana ha reagent

Mesebetsing e mengata ea khoebo, litšenyehelo tsohle tsa ho ntša metsi ka ho sebelisa baemeli ba sireletsang tikoloho li ntse li le teng 20-50% e phahameng ho feta Sodium cyanide ha e hlahlojwa ho latela boleng ba gauta ka ounce.

5. Mehopolo ea Tikoloho le Polokeho

Sodium cyanide

• Chefo e matla haholo

• Litlhoko tse tiileng tsa ho sebetsana le tsona, ho li tsamaisa le ho li ntša chefo 'meleng

• Mekhoa e metle ea timetso (INCO, SO₂/Air, H₂O₂)

• Meralo e pakiloeng ea ho latela melao tlas'a Khoutu ea Tsamaiso ea Machaba ea Cyanide

Baemeli ba ho Lulisa ba Sireletsang Tikoloho

• Chefo e tlase e matla

• Ho fokotseha ha kutloisiso ea kotsi ea sechaba

• Ho ntse ho hlokahala ho tlosa chefo ho lihlahisoa tse ling tse ling

• Tšusumetso tikolohong e itšetlehile ka mofuta oa reagent le boitšoaro ba ho senyeha

Habohlokoa, boleng ba taolo ea likotsi, ho ena le khetho ea reagent feela, e khethollang ts'ebetso ea 'nete ea tikoloho.

6. Kamohelo ea Taolo le Mekhoa ea ESG

Ka 2026:

• Sodium cyanide e ntse e lumelloa ka molao libakeng tse ngata tsa merafo tlas'a maemo a laoloang

• Lithibelo tse sa fellang li teng libakeng tse fokolang (mohlala, linaha tse khethiloeng tsa EU)

• Khatello ea ESG e khothalletsa liteko tsa li-reagent tse ling, haholo-holo bakeng sa merero e mecha

Leha ho le jwalo, boholo ba merafo e meholo e ntse e itshetlehile ka sodium cyanide ka lebaka la ho hlaka ha taolo, ho ba le inshorense, le ho ba le banka.

7. Maemo a Kopo ka 2026

Sodium Cyanide e khethoa ha:

• Ho sebetsana le lithane tse kholo, li-ore tsa maemo a tlase

• Ho hlokahala pholiso e phahameng le tlhahiso e tsitsitseng

• Meralo ea motheo ea CIP/CIL e teng e se e le teng

• Bokgoni ba ditjeo bo bohlokwa

Li-agent tsa ho ntša metsi tse mosa tikolohong li loketse ha:

• Tšebeliso ea cyanide e thibetsoe ka molao

• Mesebetsi e menyenyane kapa ea teko e etsoa

• Khatello ea laesense ea sechaba kapa ea sechaba e phahame

• Litšobotsi tsa tšepe li rata k'hemistri e 'ngoe

8. Maikutlo a Bokamoso

Ka 2026, baemeli ba ho ntsha metsi ba mosa tikolohong ba tla ha se sebaka sa bokahohleng bakeng sa sodium cyanide empa e sebetsa e le li-supplement tsa maano maemong a itseng. Sodium cyanide e ntse e le tekanyetso ea indasteri bakeng sa ho ntša khauta, ha li-reagent tse tala li ntse li tsoela pele ho fetoha ka ts'ebeliso e reretsoeng, ntlafatso ea theknoloji, le kopanyo ea lits'ebetso tse kopaneng.

Bokamoso ba ho ntsha khauta ha bo itshetlehe hodima mahlakore a kgethilweng, empa bo itshetlehile hodima ntlafatso ea ts'ebetso, taolo ea likotsi, le khetho ea reagent e ikhethileng ea ore.

9. Qetello

Li-agent tse ntšang sodium cyanide le tse sireletsang tikoloho li emela litsela tse peli tse bapileng ho metallurgy ea khauta ea sejoale-joale. Sodium cyanide e fana ka katleho e sa bapisoeng, ho atoloha le botsitso ba moruo, ha li-agent tse sireletsang tikoloho li sebetsana le lintlha tsa taolo, tsa kahisano le tsa tikoloho lits'ebetsong tsa niche.

Ka 2026, basebetsi ba nang le tsebo ha ba botse "Ke reagent efe e betere?"
Baa botsa "Ke reagent efe e loketseng lejoe lena, sebaka sena, le projeke ena?"
