pumping of the barren slurry (tailings) to the tailings storage facility. The processing plant has the capacity to treat up to 1.25 million tonnes of ore per annum. These stages can be described under three main headings: grinding and size classification to reduce .
Mine tailings are the ore waste of mines, and are typically a mud-like material. Worldwide, the storage and handling of tailings is a major environmental issue. Many tailings are toxic and must be kept perpetualy isolated from the environment. Scale of tailings production is immense, since metal extraction is usually only ounces or pounds, for ...
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.

For example, Waitoushan Iron Mine, with the tailings re-grinding and re-separating, got the iron concentrate production of 39.2kt with the grade of 65.76% via the magnetic separator [7]. 3.3. Backfill mined out area Waste rock and tailings could also be used in the backfill mined area of a mine in transition from open- pit to underground mining.
mill tailings had reached Lake Coeur d'Alene and had impacted as much as 25,000 acres of floodplain along the river. From 1932 to 1946, mine and mill operators dredged more than 15 million metric tons of tailings-contaminated sediments from the river at Cataldo Mission Flats, stockpiling recovered material on the floodplain.
The health effects discovered from radon exposure in unventilated uranium mining prompted the switch away from uranium mining via tunnel underground mining towards open cut and in-situ leaching technology, a method of extraction that does not produce the same occupational hazards, or mine tailings, as conventional mining.

Graphite tailings：xinhai will use the process of stage grinding and screening to recover the graphite from tailings. In the process of separation, flotation and shaking table is always used. If we want to achieve comprehensive recovery of several kinds of minerals from graphite tailings, we should combine several separation methods.
The mine tailings were produced from grinding and metallurgical treatment of mineral from Eloy and Brunite mines between 1952 and 1981 . The main ore minerals are pyrite, sphalerite, galena, marcasite, and pyrrhotite. Other minor sulfides include arsenopyrite, minerals of the tetrahedrite-tennantite group, chalcopyrite, and stannite .

historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the re-processing plant will be re-
Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon). Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry".
Minto Mine is a high-grade copper and gold mine that is located 240 km north of Whitehorse, Yukon. Operations are ongoing at this time and began in October 2007. Minto processes both open-pit and underground ore using conventional crushing, grinding, and flotation to produce copper concentrates with significant gold and silver credits.
Tailings is a critical consideration for the design of slurry transportation systems. Mine operators are continually looking for solutions for the safe transport, storage and disposal of tailings, as well as converting tailings into construction materials and mine backfill.
