Kolwezi concentrator

Based on the encouraging results obtained from laboratory testing, a plant test was conducted at the Kolwezi concentrator, during which a number of important factors in preparation of the fatty acid xanthate emulsion were discovered, some of which included ... 

Industrial plants that treat dolomitic ores include the Kolwezi concentrator (Kongo) and the Nchanga concentrator (Zambia), along with several smaller plants in the Kolwezi district. 

In the 1980s, a new collector (i.e. fatty acid-modified xanthate) was introduced into the Kolwezi concentrator with significant improvement in copper recovery. In 1995, collectors from the PM series were tested in the Nchanga concentrate improving results. The plant results obtained in the Kolwezi concentrate using xanthate and TY3 are compared in Table 19.10. Collector TY3 also had a positive effect on cobalt recovery.
