近年来,国外的旋涡熔炼技术发展较快。苏联已出现了旋涡电热熔炼和富氧熔炼,并用于处理铜精矿、铜锌精矿和其他含铜物料,据称获得了良好的效果。处理铜锌精矿时,可得含锌97.5%的粗锌和品位为45%的铜冰铜;金属直收率:铜98%,锌61.2%;烟气二氧化硫浓度80～85%;氧气消耗为250(米~3/吨精矿);电耗为410(度/吨精矿)。在我国,辽宁省冶金研究所和葫芦岛锌
In recent years, foreign vortex melting technology developed rapidly. The Soviet Union has seen vortex electric smelting and oxygen-rich smelting and is used to treat copper concentrates, copper-zinc concentrates and other copper-containing materials, allegedly achieving good results. In the treatment of copper-zinc concentrates, crude zinc with 97.5% of zinc and copper-matte with 45% of grade are obtained. The direct metal yield is 98% of copper and 61.2% of zinc, and the concentration of sulfur dioxide in flue gas is 80-85%. Oxygen consumption 250 (m ~ 3 / ton concentrate); electricity consumption of 410 (degrees / ton concentrate). In our country, Liaoning Provincial Institute of Metallurgy and Huludao zinc
