Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.
Mining Liners. Mining uses multiple liners for multiple functions: heap leach liners, solution pond liners, tailings dams. Check local regulations for lining materials requirements. Heap leach mining uses a chemical solution to dissolve metals in ore, which can then be collected by a liner and refined.
Most modern hardrock metal mines dispose of tailings as a wet mud, held in pits lined with clay or a synthetic liner. Many mines put the tailings back into the original mining pit. Some large mines use entire existing valleys sealed off with earthen dams, and others store tailings in natural lakes.
