Research and development trends of hydrometallurgy:An overview based on Hydrometallurgy literature from 1975 to 2019

湿法冶金研究趋势:基于1975-2019年《Hydrometallurgy》文献的综述

Modern hydrometallurgy has been developing for more than 100 years and the related articles keep piling up.Based on a bibliometric analysis of the articles in Hydrometallurgy,the most authoritative journal in the field of hydrometallurgy,we try to catch the research and development trends from a global perspective.Firstly,keywords burstness shows that rare earth,recycling,lithium,ionic liquid,and thorium are the hotspots in recent years,and the economic and technological reasons behind them were discussed in depth.Secondly,the proportion of biohydrometallurgy grows fast from 5%to 13%and the related articles are almost all about bioleaching.There are some new directions such as direct preparation of materials in hydrometallurgical processes and ion-imprinted techniques.Thirdly,the advanced instrument analysis methods such as XAFS(X-ray absorption fine structure),gene sequencing,and micro-CT promote the deep understanding of hydrometallurgy mechanism.Finally,the cooperation network and contribution of the main institutes were mapped.

当代湿法冶金已发展一百多年,相关领域的论文越来越多。《Hydrometallurgy》是湿法冶金领域最有代表性的期刊,基于对该期刊的文献计量分析,从全局角度获得湿法冶金的研究发展趋势。首先,关键词突发性筛查结果显示,稀土、回收循环、锂、离子液体和钍是近些年的研发热点,对这些热点的经济和技术背景进行探讨。其次,生物冶金文献的比例从早期的5%快速增长到近些年的13%,且相关论文主要是生物浸出。在湿法冶金过程中直接制备材料和离子印迹技术是近些年出现的新技术。第三,新出现的仪器分析方法如X射线吸收精细结构谱、基因测序和高分辨断层扫描能促进人们对湿法冶金机理的深入理解。最后,绘制并分析世界主要研究机构的合作图谱。
