Abstract

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.
