本世纪六十年代后期,在津巴布韦的两个公司采用了奥托昆普技术从镍-铜-硫的冰镍中生产电解镍。南非英-美有限公司和津巴布韦里奥廷托有限公司分别在宾都拉及卡多马附近的地方建设了采矿、选矿、熔炼及精炼厂。当时,由于该国在政治上和经济上处于隔绝状态,两个工厂的生产在技术上也是与外界隔绝的。本文介绍这两个精炼厂为适应当地的需要及提高效率和增加生产能力而进行的革新和研制工作情况。工作的重点是最大限度地提高精炼厂镍和铜的回收率,产出高品位的电积镍和生产阴极铜,但在撰写本文时,由于经济上以及生产上的考虑,里奥廷托公司的精炼厂已经停产了。
In the late 1960s, two companies in Zimbabwe used Outokumpu technology to produce electrolytic nickel from nickel-copper-sulfur iced nickel. South Africa Ying-Mei Co., Ltd. and Rio Tinto Zimbabwe Co., Ltd. built mining, beneficiation, smelting and refineries near Bindera and Kadoma respectively. At the time, the production of the two factories was also technically isolated from the outside world as the country was politically and economically isolated. This article describes the innovations and developments that these two refineries have made to meet local needs and increase efficiency and productivity. The focus of the work is to maximize the recovery of nickel and copper from refineries, to produce high-grade nickel and copper cathodes, but at the time of writing, due to economic and production considerations, Refinery has been discontinued.
