The reaction mechanism of the direct smelting of lead in KIVCET was mainly introduced,four common zinc leaching residue processing method were compared.Comparison showed that the KIVCET furnace method has a high recovery rate for met-als such as lead,zinc,copper,silver,and indium in the slag material.Lead,copper,and silver entering the crude lead can be better re-fined in the next step,and all sulfur in the slag material entered the shaft furnace flue gas for acid production,fundamentally elimi-nate the high desulfurization cost problem of producing low concentration sulfur-containing flue gas by treating zinc leaching slag separately.Combining with the conventional wet zinc smelting process to treat zinc leaching residue,can achieve harmless and re-sourceful treatment of zinc leaching slag,obtaine good economic benefit,and eliminate the potential impact on the environment caused by the accumulation of zinc leach residue.
