Kev siv cov hlau lead-zinc ore yuav tsum tau txais txiaj ntsig ua ntej nws tuaj yeem siv tau zoo dua.Txoj kev siv feem ntau tau txais txiaj ntsig yog flotation.Txij li nws yog flotation, flotation tshuaj yog ib txwm inseparable.Cov hauv qab no yog cov lus qhia rau flotation reagents siv nyob rau hauv cov hlau lead-zinc ores:
1. Lead thiab zinc flotation regulators: Regulators tuaj yeem muab faib ua inhibitors, activators, nruab nrab pH regulators, slime dispersants, coagulants thiab re-coagulants raws li lawv lub luag haujlwm hauv cov txheej txheem flotation.Regulators muaj xws li ntau yam inorganic tebchaw (xws li ntsev, bases thiab acids) thiab organic compounds.Tib tus neeg sawv cev feem ntau ua lub luag haujlwm sib txawv hauv qhov sib txawv flotation.
2. Lead thiab zinc flotation collectors.Cov khoom siv feem ntau suav nrog: xanthate thiab tshuaj dub.Xanthate chav kawm suav nrog xanthate, xanthate esters, thiab lwm yam. Sulfur nitrogen class, xws li ethyl sulfide, muaj peev xwm sau tau zoo dua xanthate.Nws muaj peev xwm sau tau zoo ntawm galena thiab chalcopyrite, thiab nws cov pyrite sau muaj peev xwm calibrated.Tsis muaj zog, zoo xaiv, ceev flotation ceev, tsawg pab tau tshaj xanthate, thiab muaj zog capture piv rau coarse hais ntawm sulfide ores.Thaum siv rau hauv kev sib cais ntawm tooj liab-lead-sulfur piv ore, nws tuaj yeem tau txais zoo dua xanthate.Zoo sorting nyhuv.Cov tshuaj dub tshuaj dub yog cov khoom siv zoo ntawm sulfide ores.Nws muaj peev xwm sau tau qis dua li ntawm xanthate.Cov khoom solubility ntawm dihydrocarbyl dithiophosphate ntawm tib cov hlau ion yog loj dua li ntawm xanthate ntawm cov ion sib raug.Dub tshuaj Nws muaj foaming zog.Feem ntau siv cov hmoov dub hauv kev lag luam xws li: No. 25 dub hmoov, butylammonium dub hmoov, amine dub hmoov, thiab naphthenic dub hmoov.Ntawm lawv, butylammonium dub hmoov (dibutyl ammonium dithiophosphate) yog cov hmoov dawb uas yooj yim Nws yog soluble hauv dej, tig dub tom qab deliquescence, thiab muaj qee yam foaming zog.Nws yog tsim rau flotation ntawm sulfide ores xws li tooj liab, txhuas, zinc, thiab npib tsib xee.
Tsis tas li ntawd, cyanide tuaj yeem tiv thaiv sphalerite, thiab zinc sulfate, thiosulfate, thiab lwm yam tuaj yeem cuam tshuam cov flotation ntawm sphalerite.
