Flotation beneficiation yog dab tsi?

Kev ua kom cov dej ntws tawm, tseem hu ua kev ua npuas dej ntws tawm, yog ib txoj kev ua cov khoom siv uas cais cov khoom muaj nqis ntawm cov khoom siv gangue ntawm qhov sib txuas ntawm cov roj-kua-khoom los ntawm kev siv qhov sib txawv ntawm cov khoom siv ntawm qhov chaw ntawm cov khoom siv sib txawv. Nws kuj tseem hu ua "kev sib cais ntawm cov khoom siv." Txhua txoj kev uas siv cov khoom sib txuas ncaj qha lossis tsis ncaj qha los cais cov khoom siv raws li qhov sib txawv ntawm lawv cov khoom siv sib txuas hu ua kev ua kom cov dej ntws tawm.

Cov yam ntxwv ntawm cov pob zeb hauv av yog hais txog cov yam ntxwv ntawm lub cev thiab tshuaj ntawm cov pob zeb hauv av, xws li qhov ntub dej ntawm qhov chaw, cov yam ntxwv hluav taws xob ntawm qhov chaw, hom kev sib txuas tshuaj lom neeg ntawm cov atoms ntawm qhov chaw, kev sib sau ua ke, thiab kev ua haujlwm. Cov pob zeb hauv av sib txawv muaj cov yam ntxwv ntawm qhov chaw sib txawv, thiab los ntawm kev siv cov kev sib txawv no nrog kev pab ntawm cov theem sib txuas, kev sib cais thiab kev nplua nuj ntawm cov pob zeb tuaj yeem ua tiav. Yog li ntawd, cov txheej txheem flotation cuam tshuam nrog kev sib cuam tshuam ntawm cov roj, kua, thiab cov khoom khov ntawm qhov sib txuas.

Cov yam ntxwv ntawm cov pob zeb hauv av tuaj yeem hloov pauv los ntawm kev cuam tshuam dag kom ua rau qhov sib txawv ntawm cov pob zeb muaj nqis thiab cov pob zeb gangue, yog li ua rau lawv sib cais yooj yim. Hauv kev flotation, cov tshuaj flotation feem ntau siv los hloov kho cov yam ntxwv ntawm cov pob zeb hauv av, txhim kho qhov sib txawv ntawm cov pob zeb hauv av, thiab nce lossis txo qhov hydrophobicity ntawm cov pob zeb hauv av. Qhov no tso cai rau kev hloov kho thiab tswj hwm tus cwj pwm flotation kom ua tiav cov txiaj ntsig sib cais zoo dua. Yog li ntawd, daim ntawv thov thiab kev txhim kho ntawm cov thev naus laus zis flotation yog khi ze rau kev siv cov tshuaj flotation.

Tsis zoo li cov yam ntxwv ntawm lub cev xws li qhov ceev thiab qhov sib nqus, uas nyuaj rau hloov pauv, cov yam ntxwv ntawm cov khoom me me ntawm cov pob zeb tuaj yeem yooj yim kho los ntawm tib neeg kev cuam tshuam los tsim qhov sib txawv uas ua tau raws li qhov yuav tsum tau sib cais. Yog li ntawd, kev ua kom dej ntws tau siv dav hauv kev sib cais cov pob zeb thiab feem ntau hu ua "txheej txheem ua cov pob zeb thoob ntiaj teb." Nws yog qhov zoo tshwj xeeb thiab siv dav rau kev sib cais cov khoom me me thiab cov khoom me me heev, ua rau nws yog ib qho ntawm cov txheej txheem siv tau zoo tshaj plaws thiab ua tau zoo hauv kev ua cov pob zeb.
