  How to reshape the future of tailings? - Metso

  2024111 · Mining involves processing of mined ore to capture valuable minerals, which in turn produces large volumes of tailings. The annual global tailings production is currently estimated to be at the range of 10-12 billion tons/annum and increasing. Therefore, it’s important to reshape tailings management and accelerate the positive change.
