Abstract：
Cobalt is a strategic and critical mineral whose demand is expected to grow rapidly. This study aims to provide a comprehensive summary of cobalt extraction and recovery research from 2012 to 2021 in the form of bibliometric analysis. The work was based on the Science Citation Index Expanded (Web of Science) and carried out using the InCites of Clarivate for bibliometric data analysis and the software VOSviewer for science mapping. By analyzing a dataset of 4967 publications, the most influential journals, countries, authors, institutions, and publications were identified, and the keyword co-occurrence networks were mapped. The China mainland produced the most publications, while the USA had the highest average number of citations per publication and the UK was the most collaborative with other countries. The keyword analysis shows that the research hotspots gradually shifted over time from early means and methods for determination of cobalt in solution to recovery of cobalt from spent lithium batteries, smelting slag, copper-cobalt ore, etc. The research will be focused on further improvement and optimization of the separation, extraction, and recovery processes of cobalt from spent batteries in recent and future years, and three approaches were promoted to facilitate economization and industrialization of the processes in this field.
摘要：
钴是一种战略性和关键矿物，其需求预计将快速增长。本研究旨在以文献计量分析的形式对2012-2021年钴的提取和回收研究进行全面总结。这项工作基于扩展的科学引文索引（WebofScience），并使用ClarivateInCites进行文献计量数据分析，并使用VOSviewer软件进行科学制图。通过分析4967种出版物的数据集，最有影响力的期刊,国家,作者,机构,并确定了出版物，并对关键词共现网络进行了映射。中国大陆产生的出版物最多，而美国每篇出版物的平均引用次数最高，而英国与其他国家的合作最多。关键词分析表明，随着时间的推移，研究热点逐渐从溶液中钴的早期测定手段和方法转移到废旧锂电池中钴的回收，熔渣,铜钴矿,等。该研究将集中在进一步改进和优化分离，提取,以及近年来和未来几年从废电池中回收钴的过程，并推广了三种方法来促进该领域流程的经济化和工业化。
