尾矿活化方法的研究进展综述

本文简要介绍我国尾矿堆存现状和尾矿资源化利用的方法，针对尾矿用作建筑材料时存在活性较差的问题，综述了现有的机械活化、热活化、化学活化等尾矿活化方法及其机理、优缺点和研究进展。分析表明，目前仍然需要多种方法结合才能达到较好的活化效果，化学活化具有成本低廉的优势，但尚不能完全代替其他活化方法，若能突破将能更好地大宗消纳尾矿，解决尾矿堆存现状及可能出现的环境污染问题。

A review on the research progress of tailings activation methods

This paper briefly introduced the current situation of tailings stockpiling and the associated resource utilization methods of tailings in China. In terms of the low activity of utilizing tailings as building materials, we summarized the research progress made in several activation methods of tailings, including mechanical activation, thermal activation and chemical activation, and the corresponding mechanisms as well as their merits and demerits. We concluded that only integrating multi-methods could achieve the optimal activation. Despite cost-effectiveness, chemical activation still cannot completely substitute other activation methods. If being addressed thoroughly, it would better serve the resource utilization of tailings and remarkably remove the potential environmental issues.
