Pyrometallurgy, rho tawm thiab ua kom huv ntawm cov hlau los ntawm cov txheej txheem cuam tshuam nrog kev siv cua sov. Cov haujlwm tseem ceeb tshaj plaws yog roasting, smelting, thiab refining. Ci, lossis cua sov hauv huab cua yam tsis muaj fusion, hloov cov sulfide ores rau hauv oxides, cov sulfur escaping li sulfur dioxide, roj.
Pyrometallurgy piav qhia nrog ib qho piv txwv yog dab tsi?
Pyrometallurgy yog ib ceg ntawm cov khoom siv hlau. … Piv txwv ntawm cov ntsiab lus muab rho tawm los ntawm cov txheej txheem pyrometallurgical suav nrog oxides ntawm cov khoom tsis tshua muaj zog xws li hlau, tooj liab, zinc, chromium, tin, thiab manganese.
txheej txheem hydrometallurgy yog dab tsi?
Hydrometallurgy koom nrog kev siv cov tshuaj aqueous rau kev rov qab cov hlau los ntawm cov hlau, cov concentrates, thiab cov khoom siv rov ua dua lossis cov khoom seem. Cov txheej txheem no yog siv rau hauv kev rho tawm ntawm cov khoom siv hluav taws xob tsawg dua lossis tsawg dua cov hlau zoo li kub thiab nyiaj.
Electrometallurgy txheej txheem yog dab tsi?
Electrometallurgy yog ib txoj hauv kev hlau uas siv hluav taws xob los tsim cov hlau los ntawm electrolysis. … Cov electrolysis tuaj yeem ua tiav ntawm cov hlau oxide molten (smelt electrolysis) uas yog siv piv txwv li los tsim cov txhuas los ntawm txhuas oxide ntawm cov txheej txheem Hall-Hérault.
Yuav ua li cas cov txheej txheem pyrometallurgical yog siv los tsim cov thawj Aluminium?
Aluminium yog tsim los ntawm electrolysis siv cov txheej txheem Hall-Herault nrog lub zog13-18 kWh/kg. Ntawm qhov kub thiab txias, qhov txo qis ntawm oxides tshwm sim hauv lub xeev khov kho.
