前言为了保护环境并为今后复原作准备,已使尾矿处置成为矿山开发和生产费用的重要组成部分。最理想的是把尾矿送回采空区;但这不是总能做到的。最好的方法可能是在距矿山几英里的符合环保要求的地区处理含水份较少的尾矿。为了节省泵送动力和热能,所有工艺用水都应循环使用。坝的大小和高度也应加以限制。 Foreword Tailings disposal has been an important part of mine development and production costs in order to protect the environment and prepare for future recovery. The ideal is to send the tailings back to the gob area; but this is not always possible. The best way to do this might be to treat tailings that contain less moisture, in areas that meet environmental requirements a few miles from the mine. To save on pumping power and heat, all process water should be recycled. Dam size and height should also be limited.
