depyritized tailings are net acid consuming and will be stored in a surface tailings management area. The pyrite concentrate is net acid generating and will be used as backfill in the underground mine workings. The majority of carbonates in the depyritized tailings were ferroan dolomite containing 10 to 15% iron (by weight)

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 during mining ...

THE TILDEN MINE There are, at present, two iron mines operating in the UP--both are in the Marquette Range. This page is devoted to the Tilden Mine, although the other (Empire) Mine is equally impressive. Marquette County's Empire and Tilden mines together produce 20% of North America's iron ore.
Abstract: Ireland's largest 19th century mining site, the Newtownards Lead Mines at Conlig and Whitespots, County Down, may present significant human and animal health and environmental risks such as exhibited by other abandoned mine sites of similar size. We present information on the distribution of lead enrichment in tailings, spoil, soil ...

Given that the phyllosilicates are responsible for the pozzolanic activity, a decisive property in the use of pozzolan materials is found in the very ﬁne-grade samples with the highest
The invention relates to a preparation method of dolomite tailing bricks, solving the problems of low forming compactness, low demolding perfectness ratio, low initial strength of brick blanks and difficult practical application existing in brick manufacture because of high water and slurry contents and fine granularity of traditional dolomite tailings.

MINTOX includes the major reaction sequences known to control the hydrogeochemistry at many base metal tailings sites.
The Mutoshi Mine is an old open pit copper mine on the Kolwezi Klippe in the west of the Congo Copperbelt. It is a reduced facies type copper deposit made up of two ore beds separated by a layer of siliceous dolomite. The mine was first opened in 1903, and was initially worked for gold.
to examine the possibility of utilizing mining tailings containing impurities as low-cost, but presumably non-ideal, raw materials in an effective way. Mine tailings from talc ore mines are rich in magnesite (70–80%). Other minerals are 10–15% talc, 5–10% chlorite, 2–10% dolomite, and 0.5–1% iron sulphides . As the alumina
