Ore beneficiation yog txheej txheem tsim khoom uas npaj cov khoom siv raw rau cov hlau smelting thiab tshuaj lom neeg kev lag luam, thiab froth flotation tau dhau los ua txoj kev pabcuam tseem ceeb tshaj plaws. Yuav luag tag nrho cov peev txheej ntxhia tuaj yeem sib cais siv flotation.
Tam sim no, flotation yog dav siv nyob rau hauv cov txiaj ntsig ntawm ferrous hlau - feem ntau yog hlau thiab manganese - xws li hematite, smithsonite, thiab ilmenite; cov hlau zoo li kub thiab nyiaj; Cov hlau tsis muaj hlau xws li tooj liab, txhuas, zinc, cobalt, npib tsib xee, molybdenum, thiab antimony, suav nrog sulfide minerals xws li galena, sphalerite, chalcopyrite, bornite, molybdenite, thiab pentlandite, nrog rau cov oxide minerals xws li malachite, cerussite, hemimorphite, thiab lwm yam. Nws kuj tseem siv rau cov ntsev uas tsis yog xim hlau xws li fluorite, apatite, thiab barite, soluble ntsev minerals xws li potash thiab pob zeb ntsev, thiab cov minerals uas tsis yog xim hlau thiab silicate minerals xws li thee, graphite, sulfur, pob zeb diamond, quartz, mica, feldspar, beryl, thiab spodumene.
Flotation tau sau ntau qhov kev paub dhau los hauv kev ua haujlwm tau txais txiaj ntsig, nrog kev nce qib thev naus laus zis tsis tu ncua. Cov ntxhia uas yav tas los suav tias tsis muaj nqi lag luam vim lawv cov qib qis lossis cov qauv nyuaj tam sim no tau rov qab los (raws li cov peev txheej thib ob) los ntawm flotation.
Raws li cov peev txheej ntxhia tau nce zuj zus, nrog cov khoom siv muaj txiaj ntsig tau faib ntau dua thiab zoo sib xws hauv cov ore, qhov nyuaj ntawm kev sib cais tau loj hlob. Txhawm rau txo cov nqi tsim khoom, kev lag luam xws li cov ntaub ntawv metallurgical thiab tshuaj tau teeb tsa cov qauv zoo dua thiab cov kev xav tau zoo rau kev ua cov khoom siv raw - uas yog, cov khoom sib cais.
Ntawm ib sab, yuav tsum tau txhim kho kom zoo, thiab ntawm qhov tod tes, qhov kev sib tw ntawm kev sib cais cov nplua-grained minerals tau ua rau flotation nce zoo dua rau lwm txoj hauv kev, tsim kom muaj kev siv ntau tshaj plaws thiab muaj txiaj ntsig zoo niaj hnub no. Thaum xub thawj siv rau sulfide minerals, flotation tau maj mam nthuav mus rau suav nrog oxide minerals thiab non-metallic minerals. Niaj hnub no, lub ntiaj teb txhua xyoo ntim ntawm cov ntxhia ua tiav los ntawm flotation tshaj li ob peb billion tons.
Nyob rau hauv xyoo tsis ntev los no, daim ntawv thov ntawm flotation technology tau nthuav dav tshaj li ntxhia ua engineering rau cov teb xws li kev tiv thaiv ib puag ncig, metallurgy, papermaking, ua liaj ua teb, tshuaj, zaub mov, khoom siv, tshuaj, thiab biology.
Piv txwv suav nrog cov flotation rov qab ntawm cov khoom tseem ceeb los ntawm cov khoom nruab nrab hauv pyrometallurgy, volatiles, thiab slag; flotation rov qab ntawm leaching residues thiab hloov chaw precipitates hauv hydrometallurgy; kev siv flotation nyob rau hauv kev lag luam tshuaj rau de-inking recycled ntawv thiab rov qab fibers los ntawm pulp pov tseg cawv; thiab cov kev siv ib puag ncig ib puag ncig xws li rho tawm cov roj hnyav hnyav los ntawm cov dej khib nyiab, sib cais cov khoom ua paug ntawm cov dej khib nyiab, thiab tshem tawm cov colloids, kab mob, thiab cov kab hlau tsis huv.
Nrog rau kev txhim kho hauv cov txheej txheem flotation thiab cov txheej txheem, nrog rau qhov tshwm sim ntawm cov tshiab, muaj txiaj ntsig zoo flotation reagents thiab cov cuab yeej, flotation yuav pom txawm tias dav siv thoob plaws ntau qhov kev lag luam thiab thaj chaw. Txawm li cas los xij, nws tsim nyog sau cia tias kev siv flotation suav nrog cov nqi ua haujlwm ntau dua (piv rau kev sib nqus los yog lub ntiajteb txawj nqus sib cais), cov kev xav tau nruj dua rau cov khoom noj me me, ntau yam cuam tshuam rau hauv cov txheej txheem flotation xav tau kev ua haujlwm siab, thiab muaj peev xwm ua rau muaj kev phom sij los ntawm cov dej khib nyiab uas muaj cov residual reagents.
