ment of a finely ground concentrate. Finding disposal sites for the tailings, produced as a waste by-product of the new system, became a necessity. Nearby valleys located between the rock hills provided these areas and the rock outcrops were used to act as buttresses for the tailings
A distinction is usually made between mineral mining wastes and coal refuse. Mineral mining wastes are usually described as being either waste rock or mill tailings. Waste rock is the coarse material that is excavated to expose the ore during mine development. Mill tailings are the residues obtained from the separation of minerals from their ores.
During mill operations, the cemented tailings facility (CTF) would be filled with both waste rock from the mine development phase and with cemented tailings. The waste rock would be used in the construction of a drain blanket and sump before the tailings are placed. Waste rock also

Paste tailings is a modification to the conventional methods of disposal of tailings (pond storage). Conventional tailings slurries are composed of a low percent of solids and relatively high water content (normally ranging from 20% to 60% solids for most hard rock mining) and when deposited into the tailings pond the solids and liquids separate.
