Kev ua kom cov pob zeb sib xyaw ua ke, tseem hu ua kev ua npuas dej sib xyaw ua ke lossis kev ua kom cov pob zeb sib xyaw ua ke, yog ib txoj kev ua kom cov pob zeb muaj nqis sib cais los ntawm cov pob zeb sib xyaw ua ke ntawm qhov sib txuas ntawm cov roj-kua-khoom los ntawm kev siv qhov sib txawv ntawm cov yam ntxwv ntawm ntau yam pob zeb hauv cov pob zeb. Nws kuj tseem hu ua "kev sib cais ntawm cov pob zeb sib xyaw ua ke." Txhua txoj kev uas siv cov yam ntxwv ntawm cov pob zeb sib xyaw ua ke ncaj qha lossis tsis ncaj qha los ua kom cov pob zeb sib xyaw ua ke raws li qhov sib txawv ntawm cov yam ntxwv ntawm cov pob zeb sib xyaw ua ke hu ua kev ua kom cov pob zeb sib xyaw ua ke.
Cov yam ntxwv ntawm cov zaub mov saum npoo av yog hais txog cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg ntawm cov khoom me me, xws li qhov ntub dej ntawm qhov chaw, qhov them ntawm qhov chaw, hom kev sib txuas tshuaj lom neeg, kev sib sau ua ke, thiab kev ua haujlwm ntawm cov atoms ntawm qhov chaw. Cov khoom me me sib txawv qhia txog qee qhov kev hloov pauv hauv lawv cov yam ntxwv ntawm qhov chaw. Los ntawm kev siv cov kev sib txawv no thiab siv kev sib cuam tshuam ntawm cov khoom, kev sib cais thiab kev nplua nuj ntawm cov zaub mov tuaj yeem ua tiav. Yog li ntawd, cov txheej txheem flotation cuam tshuam nrog cov roj-kua-khoom peb-theem interface.
Cov khoom ntawm cov zaub mov saum npoo av tuaj yeem hloov kho kom zoo dua qhov sib txawv ntawm cov khoom muaj nqis thiab cov khoom siv gangue, yog li ua rau lawv sib cais. Hauv kev flotation, cov tshuaj reagents feem ntau yog siv los hloov cov khoom ntawm cov zaub mov saum npoo av, ua kom muaj qhov sib txawv ntawm lawv cov yam ntxwv ntawm qhov chaw thiab kho lossis tswj lawv cov hydrophobicity. Qhov kev tswj hwm no tswj hwm tus cwj pwm flotation ntawm cov zaub mov kom ua tiav cov txiaj ntsig sib cais zoo dua. Yog li ntawd, daim ntawv thov thiab kev nce qib ntawm cov thev naus laus zis flotation yog ze rau kev txhim kho cov tshuaj reagents flotation.
Tsis zoo li qhov ceev lossis qhov sib nqus tau - cov khoom siv hauv cov pob zeb uas nyuaj rau hloov pauv - cov yam ntxwv ntawm cov khoom siv hauv cov pob zeb feem ntau tuaj yeem hloov kho kom tsim tau qhov sib txawv ntawm cov pob zeb kom sib cais tau zoo. Yog li ntawd, kev ua kom cov dej ntws tau siv dav hauv kev ua kom cov pob zeb zoo thiab feem ntau suav hais tias yog txoj kev ua kom cov pob zeb zoo thoob ntiaj teb. Nws yog qhov tshwj xeeb tshaj yog thiab siv dav rau kev sib cais cov khoom zoo thiab cov khoom zoo heev.
