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 moo ho kopanang teng pakeng tsa khōlo ea indasteri le phetoho ea tikoloho . Sodium cyanide (NaCN) e ntse e le Sethethefatsi sa ho Ntša Khauta se sebelisoang haholo lefatšeng ka bophara ka lebaka la bokhoni ba eona ba tekheniki bo sa bapisoeng le melemo ea moruo. Ka nako e ts'oanang, li-agent tsa ho ntša khauta tse mosa tikolohong, tse atisang ho rekisoa e le "tse se nang cyanide" kapa "li-agent tsa ho ntša khauta tse tala," li ntse li tsoela pele ho hapa tlhokomelo tlas'a melao e ntseng e eketseha ea tikoloho le meralo ea matsete e tsamaisoang ke ESG.

Ho ena le kamano e bonolo feela ea ho nkela sebaka, 'nete ea indasteri ea hona joale e bontša ho ba teng le karohano lipakeng tsa Sodium Cyanide le litsamaiso tse ling tsa 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 e le ntho e hohelang ka mohopolo, litsamaiso tse ngata tse sireletsang tikoloho li ntse li haelloa ke mehlala e tloaelehileng ea indasteri ho pholletsa le mekhatlo 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 ts'ebetso e phahameng ea ho hlaphoheloa, e kholo , haholo-holo bakeng sa li-ore tsa maemo a tlase le tse hanyetsang kamora kalafo ea pele. Li-agent tse amohelang tikoloho hangata li sebetsa hantle li-ore tsa maemo a holimo kapa tse bonolo tsa oxide , empa botsitso ba ho hlaphoheloa bo 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 li-agent tse sireletsang tikoloho li lula li le holimo ka 20-50% ho feta Sodium cyanide ha li hlahlojoa motheong oa khauta 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 fapana le khetho ea reagent feela, ke bona bo 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 se be le inshorense, le ho kgona ho boloka tjhelete.

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, di-leaching agents tse sireletsang tikoloho ha se sebaka sa sodium cyanide e akaretsang empa di sebetsa e le ditlatsetso tsa mawa maemong a itseng. Sodium cyanide e ntse e le tekanyetso ya indasteri bakeng sa leaching ya kgauta, ha di-reagents tse tala di ntse di tswela pele ho fetoha ka tshebediso e rerilweng, ntlafatso ya theknoloji, le kopanyo ya tshebetso e kopantsweng.

Bokamoso ba ho ntsha gauta ha bo itshetlehe hodima mahlakore a kgethilweng, empa bo itshetlehile hodima ntlafatso ya tshebetso, taolo ya dikotsi, le kgetho ya reagent e ikgethang ka 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?"
