Tailing Disposal Methods and Tailings Dam Construction

As there is seldom enough ground available on which the tailing of a flotation plant can be run to waste without being stacked, it is usual to impound it in some form of dam where the solids can be deposited and the water decanted off for return to the plant. It is generally advisable to recover as much of the water as possible in order not only to save the expense of obtaining a fresh supply

From Tailings to Treasure? Miners Make Advancing

Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts, another strategy is to produce thickened tailings, which are pressed or have chemicals added to remove excess water. Thickened tailings can be mixed with cement and used in construction or as backfill in underground mines.

The levels of risks involved depend on the site characteristics, including site topography, chosen method of storage and properties of tailings material and, therefore, site selection is integral to the design process and cannot

Tailingsfo Tailings Handling

Occasionally, if the tailings are coarse sand, this conveyor product can be blended with waste rock in a waste dump to form a co-disposal facility. Truck: Particularly for low tonnage tailings operations, the use of trucks are more viable for haulage to the disposal site. Difficult terrain may not permit construction of a conveyor transport system. Slurry pumping systems. Tailings pumping
