摘要:
这是一篇矿业工程领域的论文。镓在半导体、光伏发电等高科技领域具有广泛的应用前景，尤其随着半导体行业的飞速发展，人们对镓的需求量快速增长。镓在自然界并没有独立的矿床，从我国资源量和产量巨大的煤炭中回收镓资源不仅可以大大缓解镓供应紧张的局面，还可以提高资源综合利用效率，减少环境污染。本文综述了煤系镓的赋存状态和分布特征，结合我国煤炭开发利用现状分析了煤系镓资源综合利用特征，重点介绍了以粉煤灰中镓的浸出、分离方法研究现状，总结了现有研究面临的挑战与问题，提出了煤系镓资源综合利用若干建议，以期为我国煤系镓资源综合利用提高参考。
Abstract:This is a paper in the field of mining engineering. Gallium has broad application prospects in high-tech fields such as semiconductors and photovoltaic power generation. Especially with the rapid development of the semiconductor industry, people's demand for gallium is growing rapidly. There is no independent deposit of gallium in nature. Recovering gallium resources from China's huge resources and output of coal can not only greatly alleviate the shortage of gallium supply, but also improve the efficiency of comprehensive utilization of resources and reduce environmental pollution. This article reviews the occurrence and distribution characteristics of gallium in coal measures, and analyzes the comprehensive utilization characteristics of gallium resources in coal measures in combination with the current status of coal development and utilization in China. Based on the challenges and problems faced by the research, some suggestions on the comprehensive utilization of coal-based gallium resources have been put forward in order to improve the reference for the comprehensive utilization of coal-based gallium resources in China.
