摘要
论述了自金银冶炼产生的氧化渣中,采用小型鼓风炉进行还原熔炼、熔析炉除铜后制成高铋粗铅阳极板,在低电流密度下高铋粗铅合金电解精炼回收Bi工艺的特点及技术条件的控制,并取得了预期的效果。
This paper discusses the Oxide residue which produced from smelting of gold and silver ,by reducing smelting in a small blast furnace and removing copper in liquating furnace , and get the anode plate with high Bismuth, states the characteristics and technical conditions of Bismuth recovery from the crude lead alloy at low current densities
