Coal ntxuav yog siv qhov sib txawv ntawm lub cev thiab tshuaj lom neeg lub zog ntawm cov thee thiab impurities (gangue) rau kev txuag hluav taws xob thiab txo qis emissions, thiab cais cov thee thiab impurities los ntawm lub cev, tshuaj lossis microbial sorting txoj kev.Kev npaj cov thee uas feem ntau siv hauv kev tsim khoom tam sim no yog jigging, hnyav nruab nrab, flotation thiab lwm yam.
Raws li cov txheej txheem ntawm kev npaj cov thee thiab cov twj tso kua mis siv, hnyav nruab nrab ntawm cov thee npaj yog thawj qhov kev xaiv.Hnyav nruab nrab cov thee npaj yog hais txog kev siv qhov sib txawv ntawm qhov sib txawv ntawm cov thee npaj, thiab qhov nruab nrab feem ntau yog dej thiab magnetite hmoov.
