Cov khoom siv smelting
Smelting yog ib qho ntawm cov txheej txheem ntau lawm.Cov txheej txheem pyrometallurgical uas cov ntaub ntawv hlau thiab lwm yam khoom siv tau muab tso rau hauv lub qhov cub cua sov kom yaj thiab quenching thiab tempering, thiab qee qhov kev hloov pauv ntawm lub cev thiab tshuaj lom neeg tshwm sim hauv cov ntaub ntawv hauv qhov cub ntawm qhov kub siab (1300 ~ 1600K), thiaj li tsim tau crude hlau los yog hlau enrichment thiab slag.Ntxiv nrog rau kev mloog zoo, calcine, sinter, thiab lwm yam, qee zaum nws yog ib qho tsim nyog yuav tsum tau ntxiv flux kom cov nqi yooj yim rau yaj thiab txo qis rau qee cov tshuaj tiv thaiv.Tsis tas li ntawd, txhawm rau muab qhov ntsuas kub uas tsim nyog, nws yog ib qho tsim nyog yuav tsum tau ntxiv roj rau combustion thiab xa huab cua los yog oxygen enriched cua.Cov hlau tsis zoo los yog hlau ua kom pom tseeb tuaj yeem sib cais vim qhov sib txuam me me nrog cov molten slag thiab qhov ntom ntom sib txawv rau hauv ob txheej.Cov concentrates suav nrog matte thiab daj slag, uas yuav tsum tau kho los ntawm kev hloov pauv lossis lwm txoj hauv kev kom tau txais hlau.
