Ore beneficiation ndi njira yopanga yomwe imakonzekeretsa zopangira zosungunula zitsulo ndi makampani opanga mankhwala, ndipo froth flotation yakhala njira yofunika kwambiri yopezera phindu. Pafupifupi zinthu zonse zamchere zimatha kulekanitsidwa pogwiritsa ntchito flotation.
Pakalipano, kuyandama kumagwiritsidwa ntchito kwambiri pothandizira zitsulo zachitsulo-makamaka chitsulo ndi manganese-monga hematite, smithsonite, ndi ilmenite; zitsulo zamtengo wapatali ngati golidi ndi siliva; zitsulo zopanda chitsulo monga mkuwa, lead, zinki, cobalt, faifi tambala, molybdenum, ndi antimoni, kuphatikizapo mchere wa sulfide monga galena, sphalerite, chalcopyrite, bornite, molybdenite, ndi pentlandite, komanso mchere wa oxide monga malachite, cerussite, hemissiteritemorphite, calfitemorphite, ndi calferite. Amagwiritsidwanso ntchito pa mchere wopanda zitsulo zamchere monga fluorite, apatite, ndi barite, mchere wosungunuka wa mchere monga potashi ndi mchere wamchere, ndi mchere wopanda zitsulo ndi mchere wa silicate monga malasha, graphite, sulfure, diamondi, quartz, mica, feldspar, beryl, ndi spodumene.
Flotation yapeza zambiri pantchito yopindula, ndikupita patsogolo kosalekeza kwaukadaulo. Mchere womwe poyamba unkaganiziridwa kuti alibe phindu la mafakitale chifukwa cha kutsika kwake kapena mawonekedwe ovuta tsopano akubwezedwa (monga zowonjezera zowonjezera) kupyolera mu kuyandama.
Pamene chuma cha mineral chikuchulukirachulukira, ndi mchere wofunikira womwe umagawidwa bwino kwambiri komanso movutikira mkati mwa ore, zovuta zolekanitsa zakula. Kuti achepetse ndalama zopangira, mafakitale monga zitsulo ndi mankhwala akhazikitsa miyezo yapamwamba kwambiri komanso zofunikira zolondola zopangira zinthu zopangira - ndiko kuti, zinthu zolekanitsidwa.
Kumbali imodzi, pakufunika kuwongolera bwino, ndipo kwina, vuto la kulekanitsa mchere wopangidwa bwino lapangitsa kuti kuyandama kukhale kopambana kuposa njira zina, ndikukhazikitsa ngati njira yogwiritsidwa ntchito kwambiri komanso yodalirika yopezera phindu masiku ano. Poyambirira amagwiritsidwa ntchito ku mchere wa sulfide, flotation yakula pang'onopang'ono ndikuphatikiza mchere wa oxide ndi mchere wopanda zitsulo. Masiku ano, kuchuluka kwa mchere wapachaka padziko lonse wopangidwa ndi flotation ukuposa matani mabiliyoni angapo.
M'zaka zaposachedwa, kugwiritsa ntchito ukadaulo wa flotation kwakula kupitilira uinjiniya wokonza mchere kumadera monga kuteteza chilengedwe, zitsulo, kupanga mapepala, ulimi, mankhwala, chakudya, zipangizo, mankhwala, ndi biology.
Zitsanzo zikuphatikizapo kuyandama kwa zinthu zamtengo wapatali kuchokera kuzinthu zapakatikati mu pyrometallurgy, volatiles, ndi slag; kubwezeretsedwa kwa flotation kwa zotsalira za leaching ndi kusamutsidwa kumayambira mu hydrometallurgy; kugwiritsa ntchito zoyandama m'makampani opanga mankhwala pochotsa inki yamapepala obwezerezedwanso ndi kubweza ulusi kuchokera ku zakumwa zotayidwa zamkati; ndi ntchito zaumisiri wa chilengedwe monga kuchotsa mafuta ochuluka kuchokera m'matope a m'mphepete mwa mitsinje, kulekanitsa zoipitsa zabwino kwambiri ndi madzi oipa, ndikuchotsa ma colloid, mabakiteriya, ndi kufufuza zonyansa zachitsulo.
Ndi kusintha kwa njira ndi njira zoyandama, komanso kutulukira kwa zida zatsopano zoyandama, zogwira mtima kwambiri, kuyandama kudzapeza ntchito zambiri m'mafakitale ndi magawo ambiri. Komabe, ndi bwino kukumbukira kuti ntchito flotation kumafuna mkulu processing ndalama (poyerekeza ndi maginito kapena mphamvu yokoka kulekana), okhwima zofunika chakudya tinthu kukula, zambiri chikoka zinthu mu ndondomeko flotation amafuna mkulu mwatsatanetsatane ntchito, ndi ngozi angathe chilengedwe ku madzi oipa munali reagents otsalira.
