Release behavior of uranium in uranium mill tailings under ...

The behavior and availability of uranium in uranium mill tailings is dependent on the physico-chemical form of uranium and the characteristics of the tailings (Othmane et al., 2013). When uranium mill tailings are exposed to atmospheric oxygen and moisture in the tailing pond, the release of uranium is also influenced by the water in contact with the material ( Al-Hashimi et al., 1996 ).

Tailings - Wikipedia

Terminology. Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon).. Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry". These tailings contain large amounts of pyrite (FeS 2) and Iron(II) sulfide (FeS ...

In terms of environmental behaviour, the concentrate addition did not affect the geochemical behaviour of the CPB submitted to an aggressive environment using mini alteration cell tests. This study demonstrated that for the case of the Doyon mine, it would be possible to use environmental desulphurization to produce non-acid generating low sulphide tailings and a sulphide concentrate.

In order to assess the suitability of granular mill tailings as paste backfill, its properties and behaviors are required to be determined independently (Yilmaz et al., 2011a).

Tailings.info What Are Tailings? - Their nature and production

The environment and ground conditions are the most crucial parameters that control tailings storage methodology which ultimately affects the way a facility is designed, built, operated and closed. For this reason a range of alternate methods of tailings storage and discharge techniques need to be considered when designing a facility for a particular location.

Characterization of a Bacterial Community in an …

Similar to tailing samples of other lead-zinc mine sites, the Klondyke tailings are iron rich and have a low acid-neutralizing-to-acid-generating (AGP) potential ratio (Table (Table1). 1). As a result, they are acid-generating tailings, which prevents natural revegetation and complicates phytostabilization.

Site description and sampling. Samples were collected from the Klondyke mill site in Aravaipa Valley, Graham County, Arizona, where lead and zinc ores were processed from 1948 to 1958 ().Approximately 100,000 metric tons of flotation tailing were deposited into two separate piles along the Aravaipa Creek, which remains completely unvegetated.

The zinc tailings pass over a Wilfley Table which gives the operator a constant, visual picture of the efficiency of the zinc flotation machine, and also recovers additional zinc values. Zinc concentrates are fed to a Wilfley Table to remove any lead oxide values which may have floated with the zinc, and then are thickened in a Thickener.

HZL’s chosen solution was to set up a dry tailing disposal plant at Zawar Mines for dewatering application. This would reclaim a major portion of the water consumed in the main plant and reduce the environmental risk (for instance, of a tailings dam failure) by cutting the amount of water stored within the tailings.
