Ho sebetsana le Tšebeliso e Feteletseng ea Sodium Cyanide Moepong oa Khauta Leaching

Indastering ea merafo ea khauta, ts'ebetso ea cyanidation e lula e le lejoe la motheo bakeng sa ho ntša khauta ho tsoa ore. Leha ho le joalo, taba ea ho feteletseng Sodium cyanide tshebediso nakong Leaching morafong oa khauta ha e nyolle litšenyehelo tsa ts'ebetso feela empa hape e baka likotsi tse kholo tsa tikoloho le polokeho. Poso ena ea blog e shebisisa lisosa, mekhoa e sebetsang ea ho lemoha, le tharollo e sebetsang ea ho sebetsana le bothata bona bo atileng.

Ho Utloisisa Lisosa Tsa Motso

1. Litšobotsi tsa Ore

• Meraloji e rarahaneng: Ores e nang le metsoako e rarahaneng ea liminerale e ka baka ho phahama cyanide tshebediso. Ka mohlala, liminerale tsa sulfide li kopana le cyanide, 'me li etsa metsoako ea thiocyanate. Arsenopyrite le pyrrhotite ka har'a ore e ka ja cyanide ka ho etsa oxidation le karabelo e rarahaneng, ea e khelosa ts'ebetsong ea ho ntšoa ha khauta.

• Lintho tse phahameng tsa carbon: Ores e nang le carbonaceous e na le lintho tse phelang tse etsang khauta-cyanide complexes, ketsahalo e tsejoang e le "preg-robbing." Sena se qobella ho eketsoa ha cyanide ho lefella ts'ebetso e lahlehileng ea ho ntšoa, ho fella ka Tšebeliso e feteletseng.

2. Lintlha tsa Ts'ebetso

• Khudueho e sa Lekaneng: Ho se kopane ho sa lekaneng nakong ea ts'ebetso ea leaching ho etsa hore ho be le kamano e mpe pakeng tsa ore le tharollo ea cyanide. Sena se sitisa ho qhibiliha ha khauta 'me se susumelletsa basebetsi ho eketsa cyanide ka tšepo ea ho ntlafatsa litekanyetso tsa ho ntšoa.

• Maemo a tlase a pH: Cyanidation e itšetlehile haholo ka pH, e nang le sebaka se loketseng ka tloaelo pakeng tsa 10.5 le 11.5. PH e ka tlase ho mefuta ena e etsa hore cyanide e fetohe khase ea hydrogen cyanide, e fokotsa ho fumaneha ha eona bakeng sa ho qhibiliha ha khauta. Ka lehlakoreng le leng, pH e phahameng haholo e ka senya tharollo ea cyanide, hape ea kenya letsoho ho eketseheng ha tšebeliso.

3. Boleng ba Metsi

• Metsi a Thata: Metsi a nang le k'halsiamo e ngata, magnesium, le li-ion tse ling tsa tšepe a ka sebetsana le cyanide, 'me a etsa metsoako ea tšepe ea cyanide e sa keneng. Karabelo ena e felisa cyanide ka har'a tharollo ea leaching, e hlokang ho eketsoa ka cyanide.

• Likahare tsa Oksijene e Senyehileng: Le hoja oksijene e le ea bohlokoa bakeng sa oxidation ea khauta nakong ea cyanidation, maemo a feteletseng a ka potlakisa oxidation ea cyanide ka boeona, e lebisang ho senyeha ha eona ka potlako le ho eketseha ha tšebeliso.

Mekhoa ea ho Khetholla

1. Mohlala le Tlhahlobo ea Kamehla

Bokella lisampole tsa tharollo ea leaching methating e fapaneng ea ts'ebetso, ho kenyeletsoa phepelo, lipakeng, le lintlha tsa ho tsoa. Hlahloba lisampole tsena bakeng sa mahloriso a cyanide u sebelisa mekhoa e kang titration, ion chromatography, kapa colorimetric assays. Ho bapisa maemo a lekantsoeng a cyanide le a theory ho ka thusa ho tseba mekhoa e sa tloaelehang ea tšebeliso.

2. Mekhahlelo ea Ts'ebetso ea Tlhokomelo

Tsoela pele ho lekola likarolo tsa bohlokoa tsa ts'ebetso joalo ka pH, mocheso, lebelo la ho sisinyeha, le litaba tsa oksijene. Ho kheloha ho tloha mefuteng e nepahetseng ho ka bontša mathata a ka bakang tšebeliso e feteletseng ea cyanide. Kenya tšebetsong lits'ebetso tse itirisang tsa ho beha leihlo tse ka tsosang lialamo ha li-parameter li kheloha meeli e behiloeng.

3. Sebopeho sa Ore

Etsa litlhahlobo tse qaqileng tsa mineralogical le lik'hemik'hale tsa lihlopha tsa ore tse kenang. X-ray diffraction (XRD), scanning electron microscopy (SEM), le atomic absorption spectroscopy (AAS) li ka fana ka leseli mabapi le sebopeho sa ore, ho thusa ho bolela esale pele tšebeliso ea cyanide le ho lokisa ts'ebetso ea leaching ka nepo.

Litharollo Tse Atlehang

1. Tlhokomelo ea Ore

• Phekolo ea Oxidative: Bakeng sa lirafshoa tse nang le liminerale tsa sulfide, mekhoa ea ho lokisa pele oxidative joalo ka ho halika, khatello ea oxidation, kapa bio-oxidation e ka sebelisoa. Ts'ebetso tsena li senya liminerale tsa sulfide, li fokotsa ts'ebetso ea tsona ka cyanide le ho ntlafatsa ts'ebetso ea ho ntšoa ha khauta ha li ntse li fokotsa tšebeliso ea cyanide.

• Ho tlosoa ha Carbon: Tabeng ea ores ea carbonaceous, pre-leaching ka carbon activated kapa lisebelisoa tse ling tse tlosang carbon li ka thusa ho felisa phello ea ho utsoa pele ho nako. Sena se lumella cyanide hore e shebane le ho qhibiliha khauta ho e-na le ho jeoa ke taba ea carbonaceous.

2. Ho ntlafatsa ts'ebetso

• Phetoho le Phetoho ea Aeration: Netefatsa maemo a ho ferekana le aeration e nepahetseng ho khothaletsa motsoako o ts'oanang le phetisetso e nepahetseng ea oksijene. Etsa liteko tsa boemo ba sefofane ho fumana lebelo le nepahetseng la ho sisinyeha le sekhahla sa moea bakeng sa mefuta e fapaneng ea ore le maemo a ho lutla.

• Taolo ea pH: Kenya lits'ebetso tse ikemetseng tsa ho laola pH tse ka fetolang pH ea tharollo ea leaching hantle. Sebelisa lime kapa sodium hydroxide ho boloka pH ka har'a mefuta e nepahetseng, ho thibela ho senyeha ha cyanide le ho netefatsa hore khauta e qhibiliha.

3. Phekolo ea Metsi

• Ho nolofatsa: Tšoara metsi a ts'ebetso ho tlosa li-ion tse bakang boima. Li-resin tsa ion tsa phapanyetsano kapa ho nolofatsa kalaka li ka sebelisoa ho fokotsa khalsiamo le li-ion tsa magnesium, ho fokotsa ho kena-kenana le tharollo ea cyanide.

• Taolo ea Oksijene: Ntlafatsa phepelo ea oksijene tšebetsong ea leaching. Sebelisa lisensara tsa oksijene ho beha leihlo le ho laola boemo ba oksijene e qhibilihileng, ho netefatsa hore e lekane bakeng sa oxidation ea khauta empa eseng e feteletseng ho baka ho senyeha ha cyanide.

4. Tsamaiso ea Reagent

• Cyanide e nkang sebaka: Lekola ts'ebeliso ea li-reagents tse ling tsa leaching joalo ka thiosulfate, thiourea, kapa litharollo tse thehiloeng ho chloride. Lintho tsena tse nkang sebaka sena li ka fana ka tšusumetso e tlase ea tikoloho le litheko tse tlase tsa tšebeliso ha li bapisoa le Sodium cyanide, haholo-holo bakeng sa mefuta e itseng ea ore.

• Reagent Recycling: Kenya ts'ebetsong mekhoa ea ho hlaphoheloa le ho tsosolosa cyanide. Mahlale a joalo ka phapanyetsano ea ion, electrowinning, le filtration ea membrane e ka sebelisoa ho khutlisa le ho sebelisa cyanide hape ho tloha mehatleng ea leaching, ho fokotsa ts'ebeliso e akaretsang le tlhahiso ea litšila.

Mehato e thibelang

1. Koetliso ea Basebetsi

Fana ka koetliso e felletseng ho basebetsi ba merafo le ba sebetsang mabapi le lits'ebetso tsa cyanidation, ts'ebetso ea lisebelisoa le tlhokomelo. Basebeletsi ba koetlisitsoeng hantle ba na le monyetla oa ho tseba le ho rarolla mathata hang-hang, ho etsa bonnete ba hore ts'ebetso ea leaching e tsamaea hantle le ka katleho.

2. Data Analytics le Modelling

Sebelisa lisebelisoa tsa tlhahlobo ea data le mekhoa ea ho etsa mohlala ho sekaseka lintlha tsa nalane le tsa nako ea nnete. Ka ho tseba mekhoa le likamano, basebetsi ba ka bolela esale pele mathata a ka bang teng a amanang le tšebeliso ea cyanide le ho nka mehato ea ho a thibela.

3. Liphuputso le Litlhahlobo tsa Kamehla

Etsa liphuputso tsa kamehla tsa ka hare le tsa ka ntle tsa ts'ebetso ea cyanidation. Litlhahlobo tsena li ka thusa ho tseba libaka tse lokelang ho ntlafatsoa, ​​ho netefatsa hore ho tsamauoa le melaoana ea tikoloho le polokeho, le ho boloka katleho e felletseng ea ts'ebetso ea ho chesoa ha khauta.

Qetellong, ho bua ka ho feteletseng sodium cyanide Ho sebelisoa ha merafong ea khauta ho hloka mokhoa o nang le likarolo tse ngata o kenyelletsang ho utloisisa lisosa, ho kenya ts'ebetsong mekhoa e sebetsang ea ho lemoha, ho sebelisa litharollo tse nepahetseng, le ho nka mehato ea thibelo. Ka ho etsa joalo, lik'hamphani tsa merafo li ke ke tsa fokotsa litšenyehelo feela empa hape li ntlafatsa ts'ebetso ea tikoloho ea ts'ebetso ea tsona ea ho hula khauta.
