Kev muab faib rau luag
Raws li cov cuab yeej siv, nws tau muab faib ua cov tshuab ua kom sov lub tshuab ua kom sib tsoo, rov ua kom sov lub tshuab ua kom sov thiab hluav taws xob sib tsoo; raws li cov txheej txheem cov txheej txheem, nws muab faib ua flash smelting, molten pas smelting, vortex smelting, smelting oxygen-nplua nuj, huab cua smelting, smelting smelting, smelting ncaj qha ntawm sulphide mloog zoo thiab vulcanization. Ua tib zoo ua kom kub yus tus kheej, thiab lwm yam. Cov kev faib tawm ob leeg no nyuaj piav qhov tseem ceeb ntawm qhov txheej txheem zom. Cov nplais tawg smelting yog ua raws li cov khoom siv ntau los yog kneaded mloog zoo, thiab cov coke siv los ua cov roj lossis ua kom tus neeg sawv cev txo qis. Lub tshuab ua kom rov ua kom sov smelting yog ib txoj hauv kev uas cov khoom siv hmoov txhuam kom siv cov khoom siv raw, thiab cov roj tau hlawv thiab ua kom kub nyhiab los cuam tshuam. Cov hluav taws xob cua sov ua kom sib tsoo yog ib txoj hauv kev uas cov granules lossis cov ntaub ntawv hmoov siv los ua cov ntaub ntawv nyoos thiab sib tsoo los ntawm hluav taws xob cua sov.
Raws li lub ntsiab lus ntawm cov txheej txheem cov tshuaj tiv thaiv, nws muaj peev xwm muab faib ua oxidative smelting, txo smelting, txo smelting smelting, nrov nrov smelting, tsis txaus ntseeg smelting thiab cov tshuaj tiv thaiv smelting.
