    Tailings Wikipedia. Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon), 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

    Critical Mineral Recovery Potential from Tailings and Other Mine Waste Streams. Science Center Objects . Overview; The primary objectives of this one-year scoping project are to determine the feasibility of extracting byproduct mineral commodities, such as critical minerals, from mine tailings. We plan to analyze the existing data and reports

    Recovery Potential From Benson Mine Tailings The focus of this study was to evaluate the potential reuse of mixed mine tailings and waste rock in waterbalance covers WBCs. Reuse of mine waste in geoengineering applications can provide an economic advantage via offsetting raw material requirements and reducing waste volumes to manage.

    May 15, 2017· However, mine tailings may also be recycled and reused, e.g. manganese-rich tailings could be used in agro-forestry, building and construction materials, coatings, cast resin products, glass, ceramics, and glazes (Lottermoser, 2011). Increasing demands for metals, coupled with depleting reserves of high-grade primary ores, has meant that waste

    We examined the national mine waste registries from seven European countries, created to fulfil the requirements of the “Mine Waste Directive” (2006/21/EC), for their potential use as an initial source of information for the valorisation of specific mine waste deposits for their resource recovery. A set of parameters for mine waste valorisation was defined and divided into three groups
