摘要
不列颠精炼金属公司建于1931年,精炼产于澳大利亚昆士兰州芒特·艾萨的粗铅。其间,公司进行过几次扩建和改造,使铅和银的精炼能力大幅度提高。最近,对2号精炼锅操作场地进行了改扩建,使之能处理在阿旺茅斯的不列颠锌公司密闭鼓风炉和M IM公司在德国杜伊斯堡的冶炼厂密闭鼓风炉产出的粗铅。本次扩建还包括修建一座符合工业卫生标准的浮渣处理车间。本文简述现有的原生矿精炼生产,并介绍在工艺冶金学和操作方法中的一些最新改进。
Britannia Refined Metals Ltd.was built in 1931 to refine the lead bullion produced at the Mt.Isa mine in Queensland,Australia.Several periods of expansion and development have taken place over the intervening years, leading to major increases in the refining capacity for both lead and silver. Most recently the No.2 refinery kettle floor was extended to enable it to process lead bullion produced from two Imperial Smelting Furnaces (ISF), at Britannia Zinc Ltd. in Avonmouth, England and at MIM Huttenwerke In Duisburg, Germany. This expansion included the provision of a plant for the hygienic handling of drosses and skims. This paper briefly describes the present primary refining operations and gives an update on the most recent developments in the process metallurgy and operating practice that have taken place.
