一次和二次资源中钴的提取和回收技术:综述

摘要: 钴具有出色的磁性和电化学性能以及较低的导热性,作为一种战略资源,钴已经作为关键原料广泛应用于高新技术领域。然而,由于近年来电池行业的飞速发展消耗了大量钴资源,导致钴资源出现供应危机。因此,本文从总结钴矿储量和分布出发,阐明了近年来钴行业发展和消费情况,并详细地整理了不同钴资源回收方法的原理、优缺点以及研究现状。为了获得钴原料以满足下游产业的发展需求,在资源源头上,对不同种类钴资源(铜钴矿、镍钴矿、锌冶炼渣以及报废钴产品)的开发和回收将会得到发展。同时,在回收技术方面,火法-湿法联合工艺既能够通过火法煅烧改善矿相结构,又能通过后续湿法回收过程实现较高的钴回收率和钴产品纯度。因此,联合工艺将会是未来钴回收最具前景的回收工艺。

 

Extraction and recycling technologies of cobalt from primary and secondary resources: A comprehensive review

Abstract: Cobalt has excellent electrochemical, magnetic, and heat properties. As a strategic resource, it has been applied in many high-tech products. However, the recent rapid growth of the battery industry has substantially depleted cobalt resources, leading to a crisis of cobalt resource supply. The paper examines cobalt ore reserves and distribution, and the recent development and consumption of cobalt resources are summarized as well. In addition, the principles, advantages and disadvantages, and research status of various methods are discussed comprehensively. It can be concluded that the use of diverse sources (Cu–Co ores, Ni–Co ores, zinc plant residues, and waste cobalt products) for cobalt production should be enhanced to meet developmental requirements. Furthermore, in recovery technology, the pyro-hydrometallurgical process employs pyrometallurgy as the pretreatment to modify the phase structure of cobalt minerals, enhancing its recovery in the hydrometallurgical stage and facilitating high-purity cobalt production. Consequently, it represents a promising technology for future cobalt recovery. Lastly, based on the above conclusions, the prospects for cobalt are assessed regarding cobalt ore processing and sustainable cobalt recycling, for which further study should be conducted.
