Cov xib teg yog lub siab - concentration thiab haib stirring thiab Scrubbing khoom. Nws yog qhov tsim nyog siv nyob rau hauv ntau lub chaw lag luam xws li metallurgy, cov ntaub ntawv tsim tsev, kev lag luam hauv lub teeb, thiab siv los ntxuav cov khoom ntawm cov khoom. Los ntawm kev txhuam hniav thiab cov kev sib txhuam ntawm cov ntaub ntawv, cov av thiab lawv cov oxides ntawm cov khoom siv tuaj yeem tshem tawm, yog li sib sau ua cov khoom tshiab rau cov ntaub ntawv. Txhawm rau pab txhawb cov tshuaj tiv thaiv cov khoom hauv cov txheej txheem thev naus laus zis tom ntej. Lub tshuab no tshwj xeeb yog tsim nyog rau cov txheej txheem ua haujlwm hauv pob zeb. Cov ntaub ntawv uas tau muab txhuam kom txhuam tau ua rau cov flotation, tau txais txiaj ntsig thiab re - ntes. Nws tuaj yeem nce cov kev rov qab ntawm cov ua haujlwm ntawm cov ntxhia. Rau siab - concentration pulp, cov nyhuv cov nyhuv yog haj yam zoo tshaj.
