High Efficient Treatment of Zinc Leaching Residue by Using Combination Zinc Smelting Process with KIVCET Process
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.
