摘要:Abstract(#br)To extract selenium(VI) from the highly caustic leachate of copper anode slime, the Ca–Al–Cl layered double hydroxides (Ca–Al–Cl–LDHs) with a formula of Ca 2 Al(OH) 6 Cl·2H 2 O by three co-precipitation methods were synthesized. A plate-like morphology...

摘要:Abstract(#br)The SKS furnace is a horizontal cylindrical reactor similar to a Noranda furnace, however, the oxygen enriched air is blown into the furnace from the bottom. Mechanism model of the SKS process was developed by analyzing the smelting characteristics deeply. In our mod...
