Nkag siab txog All-Slime Cyanidation Gold Extraction Process hauv Kub Mines

Hauv kev rho kub , cov txheej txheem cyanidation tag nrho-slime sawv cev rau ib txoj hauv kev tseem ceeb thiab dav dav rau kev rov qab tau kub ntawm cov hlau. Cov txheej txheem no yog qhov zoo tshaj plaws rau kev kho cov khoom siv kub uas muaj kub sib tsoo zoo qhov twg kub tau kis thoob plaws hauv cov hlau hauv cov khoom me me. Cov ntawv blog no yuav nkag mus rau hauv cov ntsiab lus nyuaj ntawm cov txheej txheem rho kub cyanidation tag nrho-slime, qhia txog nws qhov tseem ceeb, cov kauj ruam ua haujlwm, thiab cov kev xav tseem ceeb.

Qhov tseem ceeb ntawm All-Slime Cyanidation

Cov txheej txheem cyanidation uas muaj cov kua nplaum tag nrho tau hloov pauv txoj kev rho kub los ntawm kev ua kom rov qab tau kub los ntawm cov ores uas yav dhau los suav tias tsis yooj yim rau kev ua. Nws tso cai rau kev rho kub los ntawm cov ores qib qis, nrog rau los ntawm cov ores nyuaj uas muaj cov zaub mov refractory. Los ntawm kev yaj kub hauv cov tshuaj cyanide , cov txheej txheem no tuaj yeem ua tiav cov nqi rov qab tau kub siab, ua rau nws yog qhov kev xaiv nyiam rau ntau qhov kev ua haujlwm khawb kub thoob ntiaj teb.

Cov kauj ruam ua haujlwm ntawm All-Slime Cyanidation Process

Ore Kev Npaj

Thawj kauj ruam nyob rau hauv tag nrho cov-slime cyanidation txheej txheem yog ore npaj. Cov kub-cov kabmob ore yog crushed thiab hauv av mus rau ib tug zoo hmoov los ua kom lub nto nto muaj rau kub dissolution. Qhov no feem ntau yog ua los ntawm kev sib xyaw ntawm crushers, grinders, thiab cov ntxaij vab tshaus kom ua tiav qhov xav tau qhov loj me. Cov ore hauv av zoo, lossis "slime," ces ntxuav kom tshem tawm cov impurities thiab npaj rau cov txheej txheem cyanidation.

Cyanidation

Thaum cov ore tau npaj lawm, nws yog tov nrog ib tug cyanide tov nyob rau hauv ib tug series ntawm agitated tso tsheb hlau luam. Cov tshuaj cyanide reacts nrog cov kub nyob rau hauv cov ore, tsim ib tug soluble kub cyanide complex. Cov tshuaj tiv thaiv no tau yooj yim los ntawm qhov muaj cov pa oxygen, uas tau nkag mus rau hauv lub tso tsheb hlau luam los ntawm aeration. Lub sijhawm ntawm cov txheej txheem cyanidation tuaj yeem sib txawv nyob ntawm seb hom ore thiab qhov xav tau kub rov qab tus nqi, tab sis nws feem ntau yog nyob ntawm ob peb teev mus rau ob peb hnub.

Kev sib cais-kua kua

Tom qab cov txheej txheem cyanidation tiav, cov slurry tshwm sim yog raug rau cov kua-kua sib cais. Qhov no feem ntau yog ua los ntawm kev sib xyaw ua ke ntawm thickeners, lim, thiab centrifuges cais cov khoom tailings los ntawm cev xeeb tub leach tov (PLS), uas muaj cov yaj kub. Cov khoom tailings yog tom qab ntawd muab pov tseg rau hauv qhov chaw cia khoom tailings, thaum PLS raug xa mus rau kev ua haujlwm ntxiv kom rov qab tau cov kub.

Kub rov qab

Kauj ruam kawg hauv cov txheej txheem cyanidation tag nrho yog kev rov qab kub. Muaj ntau txoj hauv kev uas siv tau los rov qab kub ntawm PLS, suav nrog kev nqus cov pa roj carbon activated , kev pauv ion, thiab electrowinning. Kev nqus cov pa roj carbon activated yog txoj hauv kev siv ntau tshaj plaws, qhov twg PLS raug xa mus los ntawm ntau cov kem uas muaj cov pa roj carbon activated . Cov kub cyanide complex nqus mus rau ntawm qhov chaw ntawm cov pa roj carbon, thaum cov kua seem rov qab mus rau cov txheej txheem cyanidation. Cov pa roj carbon loaded ces raug stripped ntawm cov kub siv cov kua caustic cyanide kub, thiab cov kub raug rov qab los ntawm electrowinning lossis smelting.

Cov Kev Txiav Txim Tseem Ceeb

Thaum cov txheej txheem tag nrho-slime cyanidation yog ib txoj hauv kev zoo rau kev rho tawm kub, nws kuj ua rau muaj ntau yam teeb meem thiab xav txog. Ib qho kev txhawj xeeb tseem ceeb yog kev siv cov cyanide, uas yog cov tshuaj lom neeg muaj zog heev. Kev tuav kom zoo, khaws cia, thiab pov tseg ntawm cyanide yog qhov tseem ceeb los txo qhov kev pheej hmoo ntawm ib puag ncig thiab kev noj qab haus huv cuam tshuam nrog nws siv. Lwm qhov kev txiav txim siab yog kev kho cov khoom tailings, uas tuaj yeem muaj cov cyanide residual thiab lwm yam kab mob. Kev tswj cov tailings tseem ceeb heev los tiv thaiv kev tso tawm ntawm cov kab mob no mus rau ib puag ncig thiab ua kom muaj kev ruaj ntseg mus ntev ntawm qhov chaw cia khoom tailings.

Tsis tas li ntawd, tag nrho cov txheej txheem cyanidation yuav tsum muaj peev txheej peev hauv cov cuab yeej siv thiab kev tsim kho vaj tse, nrog rau cov nqi khiav lag luam siab rau lub zog, tshuaj, thiab kev ua haujlwm. Cov nqi no tuaj yeem ua rau muaj kev cuam tshuam loj rau kev lag luam kev lag luam ntawm kev lag luam kub mining, thiab ua tib zoo xav txog yuav tsum tau muab rau kev xaiv cov txheej txheem tsim nyog thiab cov cuab yeej siv los txo cov nqi no.

xaus

Cov txheej txheem tag nrho-slime cyanidation yog ib txoj hauv kev tab sis muaj txiaj ntsig zoo rau kev rho tawm kub los ntawm cov pob zeb zoo nkauj hauv av. Los ntawm kev nkag siab txog cov kauj ruam ua haujlwm, cov kev txiav txim siab tseem ceeb, thiab cov teeb meem cuam tshuam nrog cov txheej txheem no, cov tuam txhab lag luam kub tuaj yeem txiav txim siab paub txog nws kev siv thiab ua kom zoo dua lawv cov kev ua haujlwm kub rov qab. Raws li qhov kev thov rau kub tseem nce ntxiv, cov txheej txheem cyanidation tag nrho yuav zoo li yog ib txoj hauv kev tseem ceeb rau kev ua kom tau raws li qhov kev thov no, thaum tseem hais txog kev txhawj xeeb ntawm ib puag ncig thiab kev sib raug zoo cuam tshuam nrog kev khawb kub.
