Tšebeliso ea Polyacrylamide ho Khauta le Silver Ore Extraction

Ho ntšoa ka katleho ha khauta le silevera ho tloha ore ke mokhoa o rarahaneng o hlokang taolo e nepahetseng ea lik'hemik'hale le mekhoa e tsoetseng pele ea ho sebetsa. Har'a li-reagents tse ngata tse sebelisoang meepong ea sejoale-joale.Polyacrylamide(PAM) e hlahella e le e 'ngoe ea lik'hemik'hale tsa merafo tse sebetsang ka ho fetisisa le tse sebelisoang haholo. Ka thepa e ntle haholo ea ho phaphamala le ho ikamahanya le maemo ho mefuta e fapaneng ea ore, PAM e bapala karolo ea bohlokoa ho ntlafatseng karohano, ho eketsa chai, le ho fokotsa tšusumetso ea tikoloho ts'ebetsong eohle ea khauta le silevera.

Kamoo Polyacrylamide e sebetsang ka teng ts'ebetsong ea ho ntša

1. Tokiso ea Ore

Ts'ebetso e qala ka ho sila le ho sila, nakong eo tšepe e tala e fokotsoang hore e be karoloana e ntle e loketseng bakeng sa ho tsoa. Ebe ore ena e pshatlehileng e tsoakoa le metsi le kalaka ho etsa seretse se tšoanang ka leloaleng la bolo. Sehlahisoa se hlahisoang se fana ka motheo oa ts'ebetso ea metallurgical e tlase joalo ka sedimentation, leaching, le adsorption.

2. Sedimentation le Flocculation

Ka mor'a moo, slurry e kenngoa ka har'a mochini o teteaneng oa pre-leach. Ke hona mooPolyacrylamide Flocculantsli kenyelelitsoe pele. Limolek'hule tsa PAM li thusa ho kopanya likaroloana tse tiileng tse tiileng, 'me li etsa hore li etse li-aggregate tse khōloanyane kapa "flocs." Li-flocs tsena li lula ka potlako botlaaseng ba tanka e teteaneng, e leng se etsang hore ho be le mokelikeli o hlakileng ka holimo. Mohato ona ke oa bohlokoa bakeng sa ho tlosa lintho tse tiileng tse feteletseng le ho ntlafatsa katleho ea mekhoa ea lik'hemik'hale tse latelang.

3. Cyanide Leaching

Ka mor'a karohano e tiileng-metsi, slurry e teteaneng e kena letotong la litanka tsa leaching. Litankang tsena, ho eketsoa tharollo ea cyanide ho qhaqha khauta le silevera ho tloha ore. PAM e thusa ho boloka botsitso bo nepahetseng ba slurry le ho ntlafatsa tšebelisano lipakeng tsa cyanide le likaroloana tsa diminerale. Khokahano ena e matlafalitsoeng e matlafatsa ts'ebetso ea ho cheka, e nolofalletsang khauta e ngata le silevera ho khutlisoa ho tsoa bokae bo lekanang ba ore e tala.

4. Khabone ea Adsorption

Hang ha litšepe tsa bohlokoa li qhibilihisoa ka har'a tharollo, slurry e phalla ka har'a litanka tsa carbon adsorption. Mothating ona, khabone e kentsoeng e sebelisa khauta le silevera e qhibilihisitsoeng ho tsoa tharollong. Tšebeliso ea polyacrylamide e etsa bonnete ba hore slurry e phalla ka mokhoa o ts'oanang le ntle le ho koala, e leng ho lumellang ho kopanya hantle le ho ba le adsorption e kholo. Ha puisano ena e sebetsa hantle, e phahamisa lebelo la ho hlaphoheloa ha litšepe tsa bohlokoa.

5. Elution le Metal Recovery

Khabone e kentsoeng ka tšepe e ntan'o aroloa ebe e fetisetsoa tsamaisong ea elution, moo metsi a chesang haholo kapa tharollo ea caustic cyanide e hlobolang khauta le silevera ho carbon. Tharollo e tsosolositsoeng, eo hona joale e nang le li-ion tse ngata tsa tšepe, e romeloa setsing sa ho qhibilihisa bakeng sa ho hloekisoa ho eketsehileng. Seretse se setseng—seo hangata se bitsoang mehatla—se fetisetsoa matangoaneng a tailings. Mona, PAM e boetse e sebelisetsoa ho lokisa lintho tse thata tse setseng, ho hlakisa metsi, le ho tšehetsa polokelo e bolokehileng, e ikarabellang ea tikoloho ea litšila tsa merafo.

Melemo ea ho Sebelisa Polyacrylamide Meepong ea Khauta

✅ Lihlahisoa tse Phahameng ka ho Fetisisa

Li-flocculants tsa Polyacrylamide li ka eketsa litefiso tsa ho khutlisa khauta le silevera ka ho feta 20%, ho latela lithuto tsa ntlafatso ea merafo. Karohano e ntlafetseng e etsa hore ho be le tlhahiso e kholo ea tšepe le tšebeliso e ntle ea lisebelisoa tsa tšepe.

✅ Nako ea ho sebetsa ka potlako

Ka ho potlakisa sedimentation le ho ntlafatsa phallo ea slurry, PAM e thusa ho fokotsa nako ea ho boloka li-thickeners le litanka. Sena se ka lebisa ho ts'ebetso e potlakileng ea 30%, ho ntlafatsa ts'ebetso le ho fokotsa nako ea ts'ebetso.

✅ E na le litšenyehelo ebile e tšoarella

Tšebeliso ea Polyacrylamide e thusa ho fokotsa bongata ba cyanide le li-reagents tse ling tse hlokahalang, ho fokotsa litšenyehelo tsa lik'hemik'hale. Ho feta moo, ntlafatso e ntlafalitsoeng ea ho sebelisoa ha metsi le phokotso ea ho tsoa ha lik'hemik'hale li kenya letsoho mekhoeng e tšoarellang ea merafo, e thusang ts'ebetso ho fihlela melao ea mmuso le maemo a tikoloho.

Mofani ea Tšepahalang oa Polyacrylamide bakeng sa Likopo tsa Meepo

E le setsebimofani oa lik'hemik'hale tsa ho hloekisa metsile lik'hemik'hale tsa merafo, re fana ka mefuta e mengata ea lihlahisoa tsa polyacrylamide tse loketseng ho ntšoa ha ore ea khauta le silevera. Hore na o hloka anionic, cationic, kapa PAM e seng ea ionic, rea fana ka:

• Bohloeki bo phahameng le boleng bo tsitsitseng
• Tšehetso ea tekheniki bakeng sa litekanyetso le ts'ebeliso ea ts'ebeliso
• Ho paka ka mokhoa o ikhethileng le ho fana ka thepa e ngata
• Litheko tsa tlholisano le thomello e potlakileng

Re boetse re sebelisa lilaboratori tse tsoetseng pele 'me re boloka taolo e tiileng ea boleng ho netefatsa hore sehlopha se seng le se seng se fihlela litlhoko tsa hau tse ikhethileng tsa ts'ebetso.
