Flotation, inozivikanwawo sefroth flotation kana mineral flotation, inzira yekubatsira iyo inoparadzanisa zvicherwa zvakakosha kubva kune gangue zvicherwa pagasi-liquid-solid interface nekushandisa mutsauko wepamusoro zviwanikwa zvezvicherwa zvakasiyana muore. Inonzi zvakare "interfacial separation." Chero maitiro anoshandisa zvakananga kana zvisina kunanga zvimiro zvemukati kuti awane kupatsanurwa kwechikamu zvichienderana nekusiyana kwehunhu hwepamusoro hwemaminerari particles anonzi flotation.
Hunhu hwepamusoro hwemaminerari hunoreva maitiro emuviri nemakemikari emamineral particles, senge kunyorova kwepamusoro, pamusoro pechaji, mhando dzemakemikari bond, saturation, uye reactivity yemaatomu epamusoro. Yakasiyana mamineral particles anoratidza kumwe kusiyanisa mune yavo yepamusoro zvimiro. Nekusimudzira misiyano iyi uye nekushandisa kupindirana kwemukati, kupatsanurwa kwemaminerari uye kupfumisa kunogona kuwanikwa. Naizvozvo, iyo flotation process inosanganisira gasi-liquid-solid three-phase interface.
Nzvimbo dzepamusoro dzemaminerari dzinogona kugadziridzwa zvakagadziridzwa kuti dziwedzere mutsauko pakati peakakosha uye gangue mineral particles, nekudaro kufambisa kupatsanurwa kwavo. Mukutenderera, mareagents anowanzo shandiswa kushandura nzvimbo dzepamusoro dzezvicherwa, kuwedzera mutsauko muhunhu hwavo hwepamusoro uye kugadzirisa kana kudzora hydrophobicity yavo. Uku kunyengedza kunogadzirisa maitiro ekuyangarara kwemaminerari kuti awane mhedzisiro iri nani yekuparadzanisa. Nekuda kweizvozvo, iko kushandiswa uye kufambira mberi kweiyo flotation tekinoroji yakabatana zvakanyanya nekuvandudzwa kwema flotation reagents.
Kusiyana nekuwanda kana kuti magineti susceptibility - zvicherwa zvinonyanya kunetsa kushandura - nzvimbo dzepamusoro dzemamineral particles dzinowanzo gadziridzwa kuti dzigadzire mutsauko unodiwa wepakati-maminerari pakuparadzana kunoshanda. Nekuda kweizvozvo, flotation inoshandiswa zvakanyanya mune mineral beneficiation uye inowanzoonekwa senzira yepasirese yekubatsira. Inonyanya kushanda uye yakanyanyisa kushandiswa pakuparadzaniswa kwezvinhu zvakanaka uye zvekupedzisira-zvakanaka.
