Abstract
CITIC Heavy Industries has a large installed base of grinding equipment throughout Africa
in different configurations, including high-pressure grinding rollers with ball mill and
semi-autogenous ball crusher. The total installed power of CITIC’s mills exceeds 430 MW.
In this paper, we compare several typical grinding circuits of copper in Africa with about
15 kt/d throughput based on ore properties, process selection, equipment sizing, and key
equipment capital and operating costs. Actual operating performance is also introduced.
The comparison for the following mine sites provides a general reference for the selection
of copper grinding circuits with this approximate throughput: Kamoa-Kakula Copper
Mine with high-pressure grinding rollers with ball mill circuit, and Deziwa and Sicomine
Copper-Cobalt Mines with semi-autogenous ball crusher circuits
