  • Tailings Wikipedia

    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.. The extraction of minerals from ore can be done two ways: placer mining, which uses waterOffice of Wastewater Management Hardrock Mining Wastes,Mill Tailings Total waste (rock waste and mill tailings) produced during extraction and beneficiation of minerals can range from 10% of the total raw material removed from the earth for potash to more than 99.9% for gold. Table 1 illustrates the amount of amount of waste various mining industries produced in 1992 (Bureau of Mines 1992).

The mill utilizes crushing, grinding, and froth floatation to produce a concentrate from ore. The process results in the generation of rock tailings. This technique, first used in Montana in 1911, is commonly used for the recovery and upgrading of sulfide ores.

    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.Ute Mill Tailings and Waste Rock HC FINAL,Jul 27, 2015· Collaboration Envisioning Uses for an Inactive Hard Rock Mine in ; Hinsdale County, CO”, was published in April 2011 documenting : the work of a group that consists of artists, poets, scientists, community members, landscape architects, and historians.
