Cov txheej txheem tseem ceeb ntawm zinc oxide yog flotation. Tom qab cua sov thiab sulfurization, xanthate flotation yog siv. Nyob rau hauv hom no, tus ore yog thawj deslimed, thiab ces cov slurry yog rhuab rau 50-60 ° C thiab sulfurized nrog sodium sulfide. , thiab tom qab ntawd siv high-qib xanthate thiab hmoov dub rau flotation. Yog tias vulcanized nyob rau hauv chav tsev kub, zaj duab xis vulcanization yuav tsis muaj zog thiab cov flotation nyhuv yuav ua tsis zoo. Thaum lub sijhawm tsawg-kub vulcanization, nws yog qhov yooj yim rau tsim colloidal precipitates. Ntawm qhov tsis sib xws, qhov siab dua lub vulcanization kub, qhov muaj zog ntawm cov duab dhos ua yeeb yaj kiab ua kom muaj zog, cov neeg tsis tshua muaj zog tsim nyob rau hauv cov slurry, thiab nrawm dua ntawm kev ceev. Cov concentration ntawm sodium sulfide nyob rau hauv slurry, nws tseem yog ib qho txheej txheem tseem ceeb heev thaum lub sijhawm ua kom muaj kev txwv. Sludge, hlau oxide thiab manganese oxide nyob rau hauv lub slurry yuav haus sodium sulfide thiab txo cov kev xav zoo, yog li lawv yuav tsum tau muab tshem tawm ua ntej. Thawj Sulfide thiab tom qab ntawd amine flotation txoj kev, hom no haum rau cov flotation ntawm zinc carbonate, silicate thiab lwm tus oxidized minerals.
Qhov kom zoo dua ntawm Amine Collector yog tias hauv nruab nrab alkaline, nws muaj cov txiaj ntsig zoo ntawm quartz thiab alkaline lub ntiaj teb hlau carbon. Cov ntsev tsis muaj cov nyhuv tshwj xeeb. Thaum siv cov neeg sau tau hais tias, cov sodium seem, tsis muaj qhov cuam tshuam tsis muaj qhov cuam tshuam, tab sis kuj ua kom tau txais zinc oxerals. Thawj amines muaj cov txiaj ntsig khaws muaj zog ntawm zinc oxide, tshwj xeeb tshaj yog cov muaj 12-18 cov pa roj atoms. Thawj amines yog qhov tseem ceeb tshwj xeeb, thaum lub peev xwm sau tau ntawm theem nrab thiab tertiary amines yog qhov tsis muaj zog heev. Lead thiab Zinc Flotation Cov Regulator Cov neeg tuaj yeem hloov kho cov neeg ua haujlwm, cov neeg tsis sib haum xeeb, ua rau cov neeg sib cais nruab nrab thiab rov ua haujlwm hauv lawv cov haujlwm hauv cov txheej txheem frotation.
Ntawm cov neeg inhibitors: zinc sulfate. Daim ntawv ntshiab ntawm zinc sulfate yog dawb crystal, yooj yim soluble hauv dej. Nws yog ib tug inhibitor ntawm sphalerite. Feem ntau nws muaj kev cuam tshuam cuam tshuam tsuas yog hauv alkaline slurry. Qhov siab dua phot the slurry, qhov muaj zog nws cov nyhuv inhibitis. Qhov pom tseeb ntau nws yuav tiav. Zinc sulfate ua cov tshuaj tiv thaiv hauv qab no: ZNSO4 = ZN2 ++ SN42-ZN2 + UAS DABTOLLO 2 YOG LEEJ TWG NYEEM HAUV SCOR ZN (Huag ) 2 + h2s04 = Zso4 + 2h2o hauv Alkaline Nruab Nrab muab Hzno2- thiab ZNO22-. Lawv adsorption rau cov ntxhia kom txhim kho lub hydrophilicity ntawm cov ntxhia npoo. ZN (Huag) 2 + NAHHH = NAHZNO2 + H2NE ZN (OH) 2 + NA2NOX = NAZZNO2 + nws feem ntau yog ua ke nrog Cypide, Sulium Sulfide, Sulfite lossis thiosulfate. , sodium carbonate, thiab lwm yam siv ua ke. Cov kev siv ua ke ntawm zinc sulfate thiab cyanide tuaj yeem txhim kho cov kev txwv tsis pub muaj txiaj ntsig ntawm sphaalerite. Cov zauv feem ntau siv yog: cyanide feem ntau: zinc sulfate = 1: 2-5. Nyob rau lub sijhawm no, CN- thiab ZN2 + Form colloidal Zn (CN) 2 nag lossis daus.
