Daim ntawv thov ntawm cov txhuas zinc ee yuav tsum tau txais txiaj ntsig ua ntej nws tuaj yeem siv tau zoo dua. Cov kev pab hauv txoj kev pab yog kev ua kom qab. Txij li thaum nws yog flotation, flotation tshuaj yog ib txwm muaj kev pab tsis tau. Cov hauv qab no yog kev qhia rau cov flotation reagents siv hauv Lees-Zinc ores:
1. Lead thiab Zinc Flotation Regulators: Regulators tuaj yeem faib ua cov neeg tsis muaj peev xwm, cov neeg tsis sib haum xeeb thiab rov ua haujlwm nruab nrab raws li lawv lub luag haujlwm ntawm cov txheej txheem frotation. Cov neeg tswj hwm muaj ntau cov inorganic sib xyaw ua ke (xws li ntsev, cov hauv paus thiab acids) thiab cov organic teb. Tib tus neeg sawv cev feem ntau ua yeeb yam sib txawv raws li cov huab vog sib txawv.
2. Cov hmoov txhuas thiab Zinc flotation cov neeg sau. Feem ntau cov neeg sau suav nrog: Xanthate thiab tshuaj dub. Xanthaate chav kawm muaj Xanthate, Xanthate Esters, thiab lwm yam ntawm cov chav kawm nitrogen nitrogen, muaj qhov muaj zog dua tshaj xas. Nws muaj muaj zog khaws muaj peev xwm ntawm Galena thiab Chalcoprite, thiab nws cov khoom sau pyrite yog ntsuas. Kev xaiv tsis muaj zog, kev xaiv tau zoo, ua kom nrawm dua li Xanthate, thiab muaj lub zog ntes rau cov ntxhib ntawm cov ees. Thaum siv nyob rau hauv kev sib cais ntawm tooj liab-lead-sulfur piv, nws tuaj yeem tau txais zoo dua xasthate. Zoo dua txheeb cov nyhuv nyhuv. Cov tshuaj dub dub tshuaj yog ib tug siv tau tus txheej txheem sulfide. Nws lub peev xwm sib sau yog tsis muaj zog tshaj 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 nws muaj cov khoom ua npuas dej. 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 uas yooj yim nws yog solub dub tom qab deliquescence, thiab muaj qee yam ua npuas ncauj. Nws yog qhov haum rau kev flotation ntawm sulfide ees xws li tooj liab, txhuas, zinc, thiab npib tsib.
Tsis tas li ntawd, cyanide tuaj yeem tiv thaiv sphalorite, thiab zinc sulfate, thiosulfate, thiab lwm yam. Tuaj yeem inhibit lub flotation ntawm sphalerite.
