1988年5月以来,利用凯泽(Kayser)冶炼厂开发的阳极泥处理新工艺处理本厂和外来的阳极泥,通过加入各种试剂,如CI_2,HCI,H_2SO_4以及一种有机络合剂,使得贵金属、稀有金属和砷、锑分别溶解,溶液中有价金属通过置换,中和沉淀和水解方法分别加以回收。含贵金属的置换沉淀熔成多尔合金,然后加以分离;硒和碲析出以粉状粗产品出售;砷和锑富集后以化合物形式分离出来,处理后的残留物为锡、锑渣,其中含贵金属约100g/t,再返回冶炼厂处理。除生产设备外,还配有一套独立的废水处理设备和一套烟气多级洗涤设备,以保证空气和水的排放达到最新规定的要求。吕纳恩(Lunen)冶炼厂铜电解精炼所产阳极泥,不仅含有贵金属,还含有相当数量的锡,铅,砷,锑,以及成分波动的硒和碲。1983年决定研究一种合适的工艺,这种工艺除提取贵金属外,还可提取其它有价元素。试验和研究工作大约进行了3年,最后完成了初步设计。在此基础上,由苏尔策,艾舍尔-威斯和凯泽(Sulyer,Escher-Wyss和Kayser)公司合作承担施工图设计。在进行施工图设计的同时,基建工作已开始,以使该项目在最短时间内建成。
Since May 1988, the anode mud treatment technology developed by the Kayser smelter has been used to treat the factory and the extractive anode mud. By adding various reagents such as CI_2, HCI, H_2SO_4 and an organic complexing agent, Making precious metals, rare metals and arsenic, antimony were dissolved, the solution of valuable metals by replacement, neutralization and hydrolysis were recovered. Metallocene-containing metathesis precipitate melted into Dole alloy, and then separated; selenium and tellurium precipitated to powdery crude product for sale; arsenic and antimony enriched as a compound isolated form, the treated residue was tin, antimony slag, wherein Containing precious metal about 100g / t, and then returned to the smelter. In addition to the production equipment, there is a separate set of wastewater treatment equipment and a multi-stage flue gas cleaning equipment to ensure that air and water emissions meet the latest requirements. The anode slime produced from copper electrolytic refining at the Lunen smelter contains not only precious metals but also a considerable amount of tin, lead, arsenic, antimony, and compositionally fluctuating selenium and tellurium. In 1983 decided to study a suitable process, this process in addition to extracting precious metals, but also extract other valuable elements. The experimental and research work took about three years, culminating in the preliminary design. On this basis, Sulzer, Asher-Weiss and Kayser (Sulyer, Escher-Wyss and Kayser) companies to undertake construction drawings design. At the same time as the construction drawing design, infrastructure work has begun so that the project can be completed in the shortest time.
