  How to manage tailings efficiently and …

  In theory, compacting filtered tailings should be easy, since mines tend to produce a consistent, well-graded sandy silt or silty sand tailings. The filter presses are designed to produce tailings with a geotechnical moisture content within a narrow range; modest-sized equipment can compact the tailings in thin lifts; and traditional earthworks ...
