Flotation, tseem hu ua froth flotation los yog ntxhia flotation, yog ib qho txiaj ntsig txheej txheem uas cais cov zaub mov muaj txiaj ntsig los ntawm gangue cov zaub mov ntawm cov pa roj-kua-khoom siv los ntawm kev siv qhov sib txawv ntawm qhov chaw ntawm ntau yam minerals hauv cov ore. Nws kuj tseem hu ua "kev sib cais ntawm lub ntsej muag." Txhua tus txheej txheem uas ncaj qha lossis tsis ncaj qha siv cov khoom sib txuas kom ua tiav cov khoom sib cais raws li qhov sib txawv ntawm cov yam ntxwv ntawm cov pob zeb hauv av hu ua flotation.
Cov khoom saum npoo ntawm cov ntxhia yog hais txog lub cev thiab tshuaj lom neeg cov yam ntxwv ntawm cov pob zeb hauv av, xws li deg wettability, deg nqi, hom tshuaj tiv thaiv, saturation, thiab reactivity ntawm deg atoms. Cov ntxhia sib txawv muaj qee qhov kev hloov pauv hauv lawv cov khoom nto. Los ntawm kev siv cov kev sib txawv no thiab siv kev sib cuam tshuam hauv kev sib tshuam, kev sib cais ntawm cov pob zeb hauv av tuaj yeem ua tiav. Yog li ntawd, cov txheej txheem flotation suav nrog cov roj-kua-khoom peb-theem interface.
Cov khoom saum npoo ntawm cov ntxhia tuaj yeem raug hloov kho los txhim kho qhov sib txawv ntawm cov khoom muaj txiaj ntsig thiab gangue ntxhia, yog li yooj yim rau lawv sib cais. Nyob rau hauv flotation, reagents feem ntau yog siv los hloov cov khoom nto ntawm cov ntxhia, ua kom pom qhov tsis sib xws hauv lawv cov yam ntxwv saum npoo thiab kho lossis tswj lawv cov hydrophobicity. Qhov no manipulation tswj tus cwj pwm flotation ntawm cov zaub mov kom ua tiav cov txiaj ntsig zoo sib cais. Yog li ntawd, daim ntawv thov thiab kev nce qib ntawm kev siv tshuab flotation yog ze rau kev tsim cov flotation reagents.
Tsis zoo li qhov ntom lossis sib nqus cov khoom lag luam-ntxhia uas nyuaj dua los tsim cov khoom siv hluav taws xob tsim nyog los sib cais rau kev sib cais. Yog li ntawd, flotation yog dav siv nyob rau hauv mineral beneficiation thiab feem ntau suav hais tias yog ib tug universal beneficiation txoj kev. Nws yog qhov tshwj xeeb zoo thiab siv dav rau kev sib cais ntawm cov khoom zoo thiab ultra-zoo.
