自1982年12月以来,赞比亚基特韦新钴厂一直在生产。该厂由赞比亚联合铜业有限公司(ZCCM)恩卡纳分公司Ashford,Kent的赞比亚工程服务有限公司(ZES)设计与施工。新工厂采取焙烧-浸出-电积法(RLE)处理铜钴精矿,设计能力为130,000吨/年。焙烧炉烟气与黄铁矿焙烧炉烟气混合生产硫酸。本文对赞比亚的钴生产现状作了简单的历史性评述。比较详细地介绍了实际碰到的有关投产和工艺问题的解决办法。目前工厂已达到月产钻的设计能力,还介绍了为实现设计能力所作的改造。
Since December 1982, the new cobalt-based cobalt plant in Kitwe, Zambia, has been in production. The plant was designed and constructed by Zep Engineering Services Ltd. (ZES) of Ashford, Kent, ZCCM Branch. The new facility uses a roasting-leaching-electrowinning process (RLE) to process copper-cobalt concentrates with a design capacity of 130,000 tons / year. Roaster flue gas and pyrite roaster flue gas mixed to produce sulfuric acid. This article makes a simple historical review of the status of cobalt production in Zambia. A more detailed introduction to the actual encountered on the production and process solutions to the problem. At present the factory has reached the design capacity of monthly production drilling, also introduced to achieve the design capacity of the transformation.
