【摘要】：氰化尾渣是我国的大宗危险固体废物。这种固体废物含有可回收的有价元素,如铜、铅、锌、金、银、硫、铁等。对氰化尾渣的综合利用既可以回收这些有价元素,实现矿石资源的最大化利用,又可以减少氰化尾渣中残存的药剂对环境的危害。本文从氰化尾渣的性质出发,总结了氰化尾渣的预处理方法,介绍了回收铜铅锌、硫铁、金银的研究现状,并指出现阶段存在的主要问题。针对研究现状和存在的问题,提出新工艺的开发、新药剂的研制、尾矿的再利用等发展方向。氰化尾渣的顺利解决将为社会带来一定经济效益和环境效益。
[Abstract]:Cyanide tail slag is a large amount of hazardous solid waste in China. This solid waste contains recoverable valuable elements, such as copper, lead, zinc, gold, silver, sulfur, iron, etc. The comprehensive utilization of cyanide tailings can not only recover these valuable elements, but also maximize the utilization of ore resources, as well as reduce the harm of residual pesticides in cyanide tailings to the environment. Based on the properties of cyanide tailings, the pretreatment method of cyanide tailings is summarized. The research status of recovery of copper, lead, zinc, sulfur iron, gold and silver is introduced, and the main problems existing at the stage of emergence are also pointed out. In view of the present situation and existing problems, the development of new technology, the development of new chemicals and the reutilization of tailings are put forward. The smooth solution of cyanide tailings will bring some economic and environmental benefits to the society.
