我局鼓风炉炼铜车间产出的烟尘,除含铜外,还含鍺、铅、锌、镉、铊、砷等有色和稀有金属。因其中含SiO_2较高,若直接采用湿法提鍺,不但回收率低,且其余金属难以综合利用。在毛主席革命路线指引下,我们遵照毛主席“综合利用大有文章可做”的教导,与昆明冶金研究所共同对此烟尘进行了综合回收研究,采用电炉熔炼获得了较满意的结果。在三年来的生产实践中,我们
Our bureau blast furnace smelting copper smelter workshop output, in addition to copper, but also contain germanium, lead, zinc, cadmium, thallium, arsenic and other non-ferrous metals and rare metals. Because of its high SiO 2, if the direct use of wet extraction of germanium, not only low recovery, and difficult to comprehensive utilization of the remaining metals. Guided by Chairman Mao’s revolutionary line, we conducted a comprehensive recovery study of this soot together with the Kunming Metallurgical Research Institute under the guidance of Chairman Mao’s “There are plenty of articles on comprehensive utilization” and obtained satisfactory results by electric furnace smelting. In the past three years of production practice, we
