Mining suav nrog kev rho tawm cov khoom muaj txiaj ntsig lossis cov khoom siv geological los ntawm lub ntiaj teb, suav nrog kev tshawb nrhiav, rho tawm, ua, thiab thauj khoom. Hlau smelting, ib feem tseem ceeb ntawm mining, yog txheej txheem ntawm extracting hlau xws li hlau, tooj liab, thiab txhuas los ntawm ores.
Cov kauj ruam hauv cov hlau smelting muaj xws li:
Mining: Tau txais ores uas xav tau hlau los ntawm lub ntiaj teb.
Crushing thiab Sib Tsoo: Sib tsoo cov ores rau hauv cov khoom me me rau thaj tsam zoo dua.
Concentration: cais cov khoom muaj txiaj ntsig los ntawm cov khoom pov tseg (gangue).
Smelting: Thaum tshav kub kub concentrated ore nyob rau hauv lub cub tawg ntawm kub kub kom tshem tawm cov hlau los ntawm tshem impurities.
Refining: Cov txheej txheem purification ntxiv kom ua tiav cov hlau purity xav tau.
Mining thiab smelting muaj qhov cuam tshuam rau ib puag ncig vim muaj cov txheej txheem rho tawm, tsim pov tseg, tso pa tawm, thiab kev hloov pauv toj roob hauv pes. Kev siv zog tab tom ua kom txo qis cov kev cuam tshuam no los ntawm kev siv thev naus laus zis thiab ua raws li kev tswj hwm ib puag ncig.

Mining thiab hlau smelting muaj xws li: electrodeposited titanium electrode rau cobalt,electrodeposited titanium electrode rau zinc,electrodeposited titanium electrode rau tooj liab,electrodeposited titanium electrode rau nickel-cobalt.
