Lead thiab Zinc tseem ceeb cov ntaub ntawv raw rau kev txhim kho kev lag luam niaj hnub. Nrog rau kev loj hlob sai sai, qhov kev thov rau cov txhuas thiab zinc txuas ntxiv nce, thiab cov khoom siv nyuaj-ua kom tau nce ntxiv. Nyob rau hauv cov ntsiab lus no, cov ntxhia ua tiav tshiab nrog cov phooj ywg sib sau ua ke, thiab cov neeg tsis muaj zog, thiab siv tau cov khoom siv huv thiab ua kom zoo dua qub Zinc ores. Cov hauv qab no yuav muab kev nkag siab zoo rau koj txog cov tshuaj reagents siv hauv Leas-zinc ore flotation.
Lead and Zinc flotation Collector
xanthate
Xws li cov neeg sawv cev suav nrog Xanthate, Xanthate Esters, thiab lwm yam.
Sulphur thiab nitrogen
Piv txwv li, Ethyl sulfide muaj cov peev xwm sau muaj zog dua li xasthate. Nws muaj cov peev xwm sau muaj zog rau galena thiab chalcoprite, tab sis tsis muaj zog los sau pyrite, zoo frolotation ceev, thiab tsawg dua ntau dua xasthate. Nws muaj zog khaws lub zog rau cov ntxhib cov lus ntawm sulfide ores, thiab thaum twg siv rau sorting tooj liab-lees, nws tuaj yeem ua tiav cov txiaj ntsig zoo dua li Xanthate.
Tshuaj Dub
Cov hmoov dub yog qhov ua tau zoo sau ntawm sulfide ores, thiab nws lub peev xwm sib sau yog tsis muaj zog dua li xasthate. Cov khoom siv solubility ntawm dhihydrrocarbyl dithiophosphate ntawm tib cov hlau ion yog loj dua li ntawm xasthate ntawm cov ion. Cov tshuaj dub tau ua npuas dej zoo nkauj. Feem ntau siv cov hmoov nplej dub hauv kev lag luam suav nrog: No. 25 dub hmoov, butylammon hmoov zoo, thiab naphthenic hmoov hmoov. Ntawm lawv, Butylammonium hmoov (Dibutyl ammonium dithiophetphate) yog cov hmoov dawb, yooj yim sols tom qab tshem tawm cov khoom ntiag tug. Nws yog qhov haum rau kev flotation ntawm sulfide ees xws li tooj liab, txhuas, zinc, thiab npib tsib. Cov. Nyob rau hauv weakly alkaline slurry, lub peev xwm sib sau ntawm pyrite thiab pyrrotite tsis muaj zog, tab sis kev sib sau muaj peev xwm ntawm galena muaj zog.
Lead and Zinc Flotation Regulator
Cov kev kho tuaj yeem faib ua cov neeg ua haujlwm tsis raug, cov kev hloov pauv av me, coiaulants thiab flocculants raws li lawv lub luag haujlwm ntawm cov txheej txheem frolotation. Cov neeg kho tau xws li ntau cov inorganic sib txuas (xws li ntsev, cov hauv paus thiab kua qaub) thiab cov organic sib xyaw. Tib tus neeg sawv cev feem ntau ua yeeb yam sib txawv raws li cov huab vog sib txawv.
Cyanide (nacn, kcn)
Cyanide yog cov neeg ua haujlwm ua haujlwm tau thaum lub sij hawm txhuas thiab zinc sorting. Cyanide feem ntau yog sodium cyanide thiab poov tshuaj cyascide, thiab cyilium cyanide tseem siv. Cyanide yog cov ntsev hluav taws xob tsim los ntawm cov zog muaj zog thiab cov kua qaub tsis muaj zog. Nws hydrolyzes nyob rau hauv lub slurry los ua kom muaj HCN thiab CNˉ
KCN = K⁺ + CNˉ CNN + H₂O = HCN⁺ + OHˉ
Los ntawm qhov sib npaug saum toj no, nws tuaj yeem pom tau tias nyob rau hauv Alkaline pulp, cov concentration ntawm cnˉ nce, uas tau txais txiaj ntsig rau kev cuam tshuam. Yog tias cov pH raug txo qis, hcn (hydrocyanic acid) yog tsim thiab cov nyhuv inisabities yog txo. Yog li ntawd, thaum siv cyanide, lub alkaline xwm ntawm slurry yuav tsum tau tswj. Cyanide yog tus neeg sawv cev muaj kev lom zem heev, thiab tshawb xyuas ntawm cyanide-dawb lossis cyanide-tsis muaj inhibitors tau txuas ntxiv tau ntau xyoo.
zinc sulfate
Cov khoom ntshiab ntawm zinc sulfate yog dawb crystal, yooj yim soluble hauv dej, thiab yog ib tug inhibitor ntawm sphalerite sphalerite. Feem ntau nws muaj kev cuam tshuam cuam tshuam tsuas yog hauv alkaline slurry. Qhov siab tshaj li cov pH ntawm slurry, qhov pom tseeb ntau dua nws txoj hauv kev tiv thaiv. Zinc Sulfate ua cov tshuaj tiv thaiv hauv qab no hauv dej:
Zsso₄ = Zn²⁺ + So₄
ZN²⁺ + 2H₂o = ZN (Oh) ₂ + + 2H⁺ZN (Oh) ₂ yog ib qho amphoteric compound uas yaj hauv acid los ua ntsev
ZN (Huag) ₂ + horso₄ = Zsso₄ + 2H₂o
Hauv qhov nruab nrab alkaline, hzno₂ˉ thiab zann tau txais. Lawv adsorption rau cov ntxhia kom txhim kho lub hydrophilicity ntawm cov ntxhia npoo.
ZN (Huag) ₂ + Naoh = Nahzno₂ + H₂o
ZN (OH) ₂ + 2NZNOH = NANZNO₂ + 2H₂O
Thaum zinc sulfate yog siv nyob ib leeg, lub inisence inks yog neeg pluag. Feem ntau nws yog siv ua ke nrog cyanide, sodium sulfide, sulfite sulfide, etclishing, sodium caribitia tau cuam tshuam rau sphalerite. Cov zauv feem ntau siv yog: cyanide feem ntau: zinc sulfate = 1: 2-5. Nyob rau lub sijhawm no, CNˉ thiab ZNIC daim ntawv colloidal Zn (CN) ₂ preageter.
