Mine Waste Transfer and Disposal Methods  Mine Tailings

Mine Waste Transfer and Disposal Methods Mine Tailings

Mine Tailings. Tailings are finely ground rocks and other mineral waste as a result of mineral processing. Due to the way minerals are processed, tailings can contain concentrations of processing chemicals. This can make mine tailings an environmental concern, so proper transportation and disposal are crucial.

The exploration of iron ore in small mining companies results in a large amount of unrecovered fine material, representing 35% of the run of mine. Millions of tons of useful minerals are discarded every year into tailings, incurring operation costs, raising production losses and environmental impact. In addition to the disposal of 300 t/h of this material, millions of tons are already stored

Tailings Mineral Industry Solution</h4>Paste vs. ConventionalThe advantages of paste thickeners in tailings circuits have been wellestablished for most minerals. The type of paste thickener underflow generally used for surface stacking of tailings is called thickened tailings. Thickened tailings are a suspension of solids which are relatively nonsettling and nonsegregating and which have a higher concentration and viscosity than that of conventional tailings.Common applications include a thickener with underflow pumps that are typically centrifuga

Terminology

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) 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.
The extraction of minerals from ore can be done two ways placer mining, which uses water and gravity

Environmental Risks From Mine Tailings

Environmental Risks From Mine Tailings

Aug 10, 20180183;32;Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into tailings.
