Nyob rau hauv cov txheej txheem ntawm mining thiab siv cov ntxhia cov peev txheej, Nws yog inevitable los tsim ib tug loj npaum li cas ntawm ore pov tseg. Pob zeb khib nyiab yog ib yam khoom pov tseg, suav nrog ore gravel, slag, khib nyiab, cov tailings, lwm. Yog tias cov khib nyiab no tsis raug pov tseg kom raug, lawv yuav muaj kev cuam tshuam loj rau ib puag ncig.

Kev tswj xyuas cov khib nyiab pov tseg yog ib feem tseem ceeb ntawm cov txheej txheem mining ntawm cov khoom siv pob zeb. Nws koom nrog kev kho kom zoo thiab pov tseg ntawm ntau yam khoom pov tseg uas tau tsim thaum lub sijhawm mining, yog li ntawd txo cov pa phem thiab kev puas tsuaj rau ib puag ncig. Nrog rau kev txhim kho ntawm ib puag ncig kev paub thiab kev ua raws li cov cai thiab cov kev cai nruj, mine kev tswj cov khib nyiab tau dhau los ua ib qho tseem ceeb ntawm txoj kev loj hlob ntawm kev lag luam mining.

Cov pa roj carbon dub, yog cov hmoov dub los yog cov khoom feem ntau yog tsim los ntawm carbon atoms. Vim nws qhov tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, nws plays lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam. Tshwj xeeb, nws yog dav siv hauv roj hmab, yas, inks, txheej txheej, cov khoom siv hluav taws xob, tawv chemicals, roj teeb qhuav thiab ntau lwm yam lag luam. Cov pa roj carbon dub yog ib hom ntawm cov pa roj carbon zoo, uas yog tsim los ntawm kev hlawv lossis pyrolyzing cov ntaub ntawv carbonaceous thaum tsis muaj oxygen. Tiag tiag, nws muaj cov yam ntxwv ntawm zoo conductivity, pigmentation thiab reinforcing zog. Dab tsi ntxiv, carbon dub tsis tuaj yeem txhim kho lub zog txhua yam thiab kev pabcuam lub neej ntawm cov khoom, tab sis kuj muab cov xim zoo dua thiab gloss.
