Flotation, eo hape e tsejoang e le froth flotation, ke mokhoa oa ho lokisa liminerale o arolang liminerale tsa bohlokoa ho tsoa ho liminerale tsa gangue sehokelong se tiileng sa khase ka ho eketsa liphapang tsa thepa e kaholimo ea liminerale tse fapaneng. E boetse e bitsoa "karohano ea sefahleho". Ts'ebetso efe kapa efe e sebelisang likhokahano tsa mekhahlelo ka kotloloho kapa ka mokhoa o sa tobang ho arola likaroloana tsa liminerale tse ipapisitseng le liphapang tsa thepa ea bona ea sefahleho e bitsoa flotation.
Mehaho ea bokaholimo ba liminerale e bua ka litšoaneleho tsa 'mele le tsa lik'hemik'hale tsa bokaholimo ba liminerale, joalo ka metsi a holim'a metsi, thepa ea motlakase ea holim'a metsi, mefuta ea litlamo tsa lik'hemik'hale holim'a liathomo tse holim'a metsi, saturation le reactivity. Likaroloana tse fapaneng tsa liminerale li bonts'a thepa e fapaneng ea holim'a metsi, 'me ka ho sebelisa liphapang tsena ka thuso ea li-interfaces, ho ka finyelloa karohano ea liminerale le ho ntlafatsa. Ka hona, ts'ebetso ea ho phaphamala e kenyelletsa tšebelisano ea khase, mokelikeli le mekhahlelo e tiileng sehokelong.
Thepa ea bokaholimo ba liminerale e ka fetoloa ka ho kenella ka maiketsetso ho holisa phapang lipakeng tsa liminerale tsa bohlokoa le liminerale tsa gangue, ka hona ho bebofatsa karohano ea tsona. Ha ho phaphamala, li-reagents tsa flotation li sebelisoa hangata ho fetola thepa ea bokaholimo ba liminerale, ho ntlafatsa phapang lipakeng tsa liminerale, le ho eketsa kapa ho fokotsa hydrophobicity ea bokaholimo ba liminerale.

Ho fapana le likarolo tsa 'mele tse kang density le magnetic susceptibility, tseo ho leng thata ho li fetola, thepa ea bokaholimo ba likaroloana tsa liminerale e ka sebelisoa habonolo ka ho kenella ha batho ho hlahisa phapang e finyellang litlhoko tsa karohano. Ka lebaka leo, flotation e sebelisoa haholo karohanong ea liminerale 'me hangata e bitsoa "mokhoa oa ho sebetsana le liminerale ka bophara." E sebetsa ka ho khetheha ebile e sebelisoa ka mokhoa o pharaletseng bakeng sa ho arohana ha likaroloana tse ntle le tse ntle haholo, e leng se etsang hore e be e 'ngoe ea mekhoa e mengata le e sebetsang ka ho fetisisa ea ho sebetsana le liminerale.
