Mining equipment that’s compact, cost-effective and durable over time has made a positive impact on mining efficiency and production One of the greatest of these benefits is waste and chemicals reduction The use of manganese dates back to the Stone Age when manganese dioxide created the pigments used in cave paintings
However, the specific gravity or unit weight of waste rock from the mining of iron ore and taconite will be considerably higher than that of conventional aggregat The specific gravity of waste rock can be expected to range from 24 to 30 for most rock types and from 32 to 36 for waste rock from iron ore and taconite minings Mill Tailings
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
For example, Waitoushan Iron Mine, with the tailings re-grinding and re-separating, got the iron concentrate production of 392kt with the grade of 6576% via the magnetic separator  33 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
It in proves the grade and purity of ore, regulates size, and removes unwanted constituents (gangue minerals) It also makes a second waste stream, mill waste or tailings Tailings are finer grained than mine rock and are mixed with water to make slurry that keeps down dust Failure or leakage of tailings ponds is an environmental problem
