Sustainable Development Goals in Mine Tailings Management: Targets and Indicators

Minerals and metals are essential to the economic and social development of our society, and they are critical to modern life. The continuous exploitation of mineral resources has led to a large amount of waste, which has a large impact on the environment. One of the main streams of wastes in mining is mine tailings, which are produced in mineral processing plants. The mining industry must enhance its contribution to achieving sustainable development by incorporating the sustainable development goals into its operations. The objective of this article is to define targets and indicators for mine tailings management to achieve the sustainable development goals, defined in the 2030 Agenda for Sustainable Development by the United Nations. The result of this study is a collection of indicators proposed to measure the progress of mine tailings management towards sustainable development.

Lessons from Tailings Dam Failures—Where to Go from Here?

Different regions worldwide have adopted various approaches to tailings management, as a result of the site settings and local practices as they have evolved. Tailings dam failures have continued to occur in both developing and developed countries, necessitating a range of tailings management approaches. These failures, while rare, continue to occur at a frequency that exceeds both industry and society expectations, and there is much to be learned from well-documented cases. Tailings management continues to be overly reliant on a net present value approach using a high discount factor, rather than a whole-of-life approach that may result in safer and more stable tailings facilities and may also facilitate the eventual mine closure. There is a need for the further development and implementation of new tailings management technologies and innovations, and for the application of whole-of-life costing of tailings facilities. Changes in tailings management will most readily be achieved at new mining projects, making change across the minerals industry a generational process.

Draft Genome Sequence of Arthrobacter sp. Strain 260, Isolated from a Uranium Tailings Management Facility in Northern Saskatchewan, Canada

The 3.9-Mbp draft genome sequence of Arthrobacter sp. strain 260, which was isolated from a uranium tailings management facility, is reported. The sequence may help determine the bioremediation potential of this strain and facilitate further research aimed at a better understanding of the hypertolerance of this genus to extreme conditions.
