Geochemistry of a copper mine tailings deposit in

Dec 10, 2018· The copper mineralisation at Ulveryggen was discovered in the very start of the 20th century with subsequent prospecting studies by various owners over several decades. Folldal Verk A/S opened the Ulveryggen copper mine in 1972, and operated its flotation-based ore dressing plant next to Repparfjorden until closure in 1978.

Geotechnical Properties of Mine Tailings Journal of

The engineering properties of tailings are important for the safety evaluation and engineering design of tailing dams. In the present study, laboratory experiments were performed to investigate the geotechnical properties of four different tailings, including two iron tailings (coarse and fine) and two copper tailings (coarse and fine).

Mar 22, 2019· INTRODUCTION. Mine tailings constitute the major waste product from extractive mineral industries and are made up of a fine‐grained slurry of milled rock, process chemicals, and elevated concentrations of metals from residual ore minerals (Kvassnes and Iversen 2013).In Norway, there are presently 7 active sites where mine tailings are disposed of through submarine pipes into fjords, and

Mine Tailings groundtruthtrekking.org

Mine tailings are the ore waste of mines, and are typically a mud-like material. Worldwide, the storage and handling of tailings is a major environmental issue. Many tailings are toxic and must be kept perpetualy isolated from the environment. Scale of tailings production is immense, since metal extraction is usually only ounces or pounds, for

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
