Processing of ores for the extraction of minerals and metals commonly produces a waste material, tailings, consisting of ground rock and process water. In recent years, catastrophic failures of tailings facilities such as at Mount Polley in Canada and Fundao and Brumadinho in Brazil have caused immense pressure on mining companies to improve disclosure and risk related to tailings storage facilities. In 2020, after campaigns from influential investors, the Global Tailings Review was convened, and a Global Industry Tailings Management Standard was released. Many of the world’s largest mining companies, as members of the International Council on Mining and Metals, have committed to implement the standard. Companies and researchers are also investigating technology alternatives to reduce production of tailings or modify ore processing to generate tailings that can be more safely contained with lower chance of environmental impacts. Improved tailings management is a critical aspect to allow mining companies to restore trust with regulators and communities of interest, and to be able to responsibly supply metals critical for clear technologies and a low carbon future. The presentation will discuss some of the opportunities and challenges to improve tailings practices. It will also give a brief overview of the GMPA Global Action on Tailings initiative.
