Fifty-Seven Major Tailings Disasters Since 2000
Using tailings insights to support safer TSF management
TSFs are some of the world’s biggest engineering structures, and one of the greatest risks for mine owners, and the communities and environments in which they operate, is the far-reaching damage that occurs if they fail.
February marked the two-year anniversary of one of the most significant tailings dam failures in history – the Córrego do Feijão operation in Brumadinho, Brazil which took 270 people’s lives.
The Brumadinho tailings disaster triggered an unprecedented overhaul of global safety regulations leading to the introduction, in mid-2020, of the world’s first global safety standards for tailings management.
Resources companies are now required to be more transparent in their disclosure of tailings risk and insurers have been quick to line-up behind the new standards making insurance cover difficult to secure unless miners can demonstrate standards compliance.
