19世纪90年代特雷尔厂开始熔炼其邻近的罗斯兰矿所产铜金矿石。当罗斯兰矿趋于贫竭时,就开始处理来自不列颠哥伦比亚省其它矿山的手选方铅矿石。随着本世纪最初20年间浮选分离铅、锌、铁硫化矿物技术的发展,位于不列颠哥伦比亚省金伯利的沙利文大型矿体就成为特雷尔铅锌冶炼厂发展的基地。铅熔炼开始于1901年,锌电解开始于1916年,到1984年,特雷尔冶金联合企业已产出铅、锌各一千万吨。其目前生产能力为每年27万吨锌和11万吨铅。本文回顾了特雷尔厂生产工艺演变的历史,着重介绍了始于70年代的;F车间现代化改造规划,也叙述,计划于80年代末引进的QsL氧气炼铅工艺。炼铅的现代化改造将使其生产能力扩大到最高可年产16万吨铅。
The Terrell plant began smelting the copper-gold ore from its neighboring Roseland mine in the 1890s. As the Roslan mine tended to become depleted, it began to process the hand-chosen galena from other mines in British Columbia. With the flotation separation of lead, zinc and iron sulphide mineral technologies in the first two decades of this century, the Sullivan large ore body located in Kimberley, British Columbia has become a base for the development of the Terrell lead-zinc smelter. Lead smelting began in 1901, zinc electrolysis began in 1916, and by 1984 Trail Metallurgical Co had produced 10 million tonnes of lead and zinc each. Its current production capacity is 270,000 tons of zinc and 110,000 tons of lead a year. This paper reviews the history of Trelleborg’s evolution of manufacturing processes, highlighting the plans for the modernization of F’s plant dating back to the 1970s and the QsL Oxygen Lead Smelting Process, which was introduced in the late 1980s. The modernization of lead smelting will expand its production capacity to an annual output of 160,000 tons of lead.
