Abstract The development of renewable energy sources, electric vehicles and lithium-ion batteries has increased the demand for cobalt from the African Copperbelt that traverses the Democratic Republic of Congo (DRC) and Zambia. This increased demand has enabled the modernization of the process technology used across the region, resulting in the move from direct electrowinning of copper to solvent extraction-electrowinning. With this change has come a variety of technical challenges in the recovery of cobalt from these sources. The expansion markets for cobalt has resulted in a switch in the form of cobalt produced at the mine site, from metal cathode to cobalt hydroxide. In this paper, we provide an overview the processes currently used to produce cobalt from these copper-cobalt ores. The challenges for the technology in the context of the evolving markets for cobalt are highlighted.

从非洲铜带上的铜钴矿生产钴——概述

摘要 可再生能源、电动汽车和锂离子电池的发展增加了穿越刚果民主共和国（DRC）和赞比亚的非洲铜带对钴的需求。这种不断增长的需求推动了该地区使用的工艺技术的现代化，从而从铜的直接电解提取到溶剂萃取-电解提取。随着这种变化，从这些来源中回收钴的过程中出现了各种技术挑战。钴市场的扩张导致矿场生产的钴的形式从金属阴极转向氢氧化钴。在本文中，我们概述了目前用于从这些铜钴矿石中生产钴的工艺。
