Ore hnav khaub ncaws yog kev lag luam ntau lawm uas npaj cov khoom siv raw rau cov hlau smelting thiab kev lag luam tshuaj. Froth flotation tau dhau los ua ib txoj hauv kev tseem ceeb tshaj plaws ntawm kev ua ntxhia. Yuav luag tag nrho cov peev txheej ntxhia tuaj yeem sib cais siv flotation.
Flotation yog tam sim no dav siv nyob rau hauv kev ua cov ferrous hlau ore dominated hlau thiab manganese, xws li hematite, smithsonite, thiab ilmenite; Cov hlau muaj txiaj ntsig zoo li kub thiab nyiaj; Cov hlau tsis muaj hlau xws li tooj liab, txhuas, zinc, cobalt, npib tsib xee, molybdenum, thiab antimony, xws li sulfide cov zaub mov zoo li galena, sphalerite, chalcopyrite, chalcocite, molybdenite, thiab pentlandite, nrog rau cov oxide minerals xws li malachite, morphirite, thiab hemirsite. non-metallic ntsev minerals xws li fluorite, apatite, thiab barite; thiab soluble ntsev minerals xws li sylvite thiab pob zeb ntsev. Nws kuj yog siv rau kev sib cais ntawm cov hlau tsis muaj hlau thiab silicates, 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 cov pob zeb hauv av, nrog kev ua haujlwm txuas ntxiv mus. Txawm tias qib qis thiab cov ntxhia hauv cov txheej txheem ua haujlwm yav dhau los suav tias yog kev lag luam tsis siv tau tam sim no tuaj yeem rov qab tau thiab siv tau (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 zoo faib ntau dua thiab sib txawv hauv cov ores, qhov nyuaj ntawm kev sib cais nce. Txhawm rau txo cov nqi tsim khoom, kev lag luam xws li metallurgy thiab tshuaj lom neeg xav tau cov qauv zoo dua thiab kev ua tiav rau cov khoom siv raw, piv txwv li, cov khoom sib cais.
Ntawm ib sab tes, yuav tsum tau txhim kho kom zoo; Ntawm qhov tod tes, flotation nce qhia tau zoo dua lwm txoj hauv kev los daws qhov kev sib tw ntawm cov nplua nuj nplua nuj uas nyuaj rau kev sib cais. Nws tau dhau los ua txoj kev siv ntau tshaj plaws thiab cog lus ntxhia ua txoj kev niaj hnub no. Thaum xub thawj siv rau sulfide minerals, flotation tau maj mam nthuav mus rau oxide minerals, non-metallic minerals, thiab lwm yam. Tam sim no, ntau lab tons ntawm cov zaub mov tau ua tiav los ntawm flotation thoob ntiaj teb txhua xyoo.
Nyob rau hauv xyoo tsis ntev los no, daim ntawv thov ntawm flotation technology tsis txwv rau cov ntxhia ua engineering tab sis tau nthuav dav rau kev tiv thaiv ib puag ncig, metallurgy, papermaking, ua liaj ua teb, tshuaj, zaub mov, khoom siv, tshuaj, thiab biology.
Piv txwv li, flotation yog siv los rov qab cov khoom tseem ceeb ntawm cov khoom nruab nrab ntawm pyrometallurgy, volatiles, thiab slags; kom rov qab tau cov kua qaub residue thiab cov khoom precipitated los ntawm hydrometallurgy; rau deinking ntawm recycled ntawv thiab fiber ntau rov qab los ntawm cov kua txiv hmab txiv ntoo pov tseg hauv kev lag luam tshuaj; thiab rau rho tawm cov roj crude hnyav los ntawm cov dej hauv cov xuab zeb, sib cais cov khoom ua paug me me, colloids, kab mob, thiab cov kab hlau tsis huv los ntawm cov dej phwj tuaj, uas yog cov ntawv thov hauv ib puag ncig engineering.
Nrog rau kev txhim kho hauv cov txheej txheem flotation thiab cov txheej txheem, nrog rau qhov tshwm sim ntawm cov tshiab thiab muaj txiaj ntsig flotation reagents thiab cov cuab yeej siv, flotation yuav pom kev siv dav hauv ntau qhov kev lag luam thiab thaj chaw. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev siv cov txheej txheem flotation suav nrog cov nqi ua haujlwm ntau dua vim yog cov tshuaj reagents (piv rau kev sib nqus thiab nqus sib cais); nruj me ntsis rau pub particle loj; ntau yam cuam tshuam hauv cov txheej txheem flotation, xav tau hight tech precision; thiab cov dej khib nyiab uas muaj cov reagents residual uas tuaj yeem tsim kev puas tsuaj rau ib puag ncig.
