Tailings dam - Wikipedia

A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive. Solid tailings are often used as part of the structure itself. Tailings dams rank among the largest engineered structures on earth. The Syncrude Mildred Lake Tailings Dyke in Alberta, Canada, is an embankment dam about 18 kilometres (11 mi) long and from 40 A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue.

Mineralogical Examination of Gold Processing Plant Tailings

24/10/2019  The results of the mineralogical examination of old sulphide and oxidized gold ore tailings of a mining and processing plant in the Krasnoyarsk Territory are presented. Secondary mineral forms of antimony, namely, antimony bloom Sb 2 O 3 and tripuhyite FeSBO 4, as well as iron are found. Gypsum in the waste is a newly formed phase, undetected in the initial ore, revealed in sulphide and mixed ore tailings and is absent in oxidized ore tailings. 24/10/2019  The results of the mineralogical examination of old sulphide and oxidized gold ore tailings of a mining and processing plant in the Krasnoyarsk Territory are presented.

Tailings are variable by essence with mining and processing. For instance, early Pb-Zn tailings are generally pyrite-poor as pyrite was valorized for sulphur. Since a few decades, pyrite is dumped in tailings, changing radically their composition (and AMD behavior). We should talk of tailings stratigraphy here. Other variations may be observed with depth. On the opposite, the horizontal ...Tailings are variable by essence with mining and processing. For instance, early Pb-Zn tailings are generally pyrite-poor as pyrite was valorized for sulphur.
