Results are presented and discussed concerning the radiometric survey of the Barzava uranium mine tailings Arad District, Romania, a 20,000 m 3 sterile dump, before and after rehabilitation. Before rehabilitation, gamma dose rates in the air over the tailings varied between 200 and 2,400 nSv h 1, at 3 cm and between 190 and 1,580 nSv h 1 at 1 m above the soil, dropping to 114 ...

Rehabilitation will begin when a mine is operating and continue well after the mine is closed. While there are best practice principles and guidelines for closure planning, each project and each operating mine is unique including geological, climatic, metallurgical, hydrological, economic and cultural aspects.
Uranium mine rehabilitation relies on the same principles, frameworks, standards and general guidance that apply to rehabilitation practice across the resources industry. Planning the closure of a uranium mine, as with all mines, begins with the first planning for development and operation of the mine.
Description. The project involved a trial study of rehabilitation of the side slopes of embankments raised by the upstream construction method to be undertaken on a large tailings facility at Gushan and for associated laboratory trials to be undertaken by MIMR at Maanshan.
The conventional approach to the disposal of fine coal mine tailings, which involves piping the tailings as an aqueous slurry to a storage where they remain in the form of a permanent wet deposit, is becoming unacceptable. This approach is a legacy of a contain and forget mentality, which has economic advantages only in the...

2013-7-2accepted method of mine rehabilitation. The predicted long term stability of the landform due to the influence of tailings compression is a key factor to be considered in the design of the landform. The project investigates the settlement that had occurred at a mine site that was rehabilitated using this method of rehabilitation. The total ...
Overall, reduced ecotoxicity effects were confirmed in rehabilitated compared to unrehabilitated tailings. This suggests that rehabilitation as a post-mining restorative strategy has strong positive influence on mine tailings.
2010-12-17Rehabilitation of the tailings surface may be extremely difficult as the tailings in the pit may continue to consolidate for a longer period long after the rest of the tailings have stabilised. This must be taken into consideration when using this type of storage.
Tailings are mixtures of crushed rock and processing fluids from mills, washeries or concentrators that remain after the extraction of economic metals, minerals, mineral fuels or coal from the mine resource e.g., Fig. 1a Hudson-Edwards et al., 2001, Younger and Wolkersdorfer, 2004, Lottermoser, 2007.The word tailings is generic as it describes the by-product of several extractive ...
