贵阳冶炼厂生产电锌的主要原料,是氧化铅锌矿经火法富集产出的烟尘,由于其成分复杂(表1),对生产过程各项技术经济指标影响很大,为了进一步提高电锌质量和金属综合回收率,提高电流效率,降低电耗,改善劳动条件,自1972年以来,我们在综合 Due to its complex composition (Table 1), the main raw material for producing electricity zinc in the Guiyang smelter is the smoke and dust generated from the oxidation of lead and zinc oxide by the fire method. It has a great impact on various technical and economic indicators of the production process. In order to further improve the electricity Zinc quality and metal recovery rate, improve current efficiency, reduce power consumption, improve working conditions, since 1972, we are in the comprehensive
