The research shows the role historical tailings will play in the secondary supply of critical raw materials like tungsten. It also shows how the geometallurgical approach will play a significant role in assessing the feasibility of reprocessing such mine wastes, and developing efficient methods where residues that are inert and environmentally safe will be left behind. This holistic approach to reprocessing such historical mine wastes will contribute to the mining industry moving towards the circular economy. The Yxsjöberg case study is a good example of how the supply risk-reducing measure in material criticality would contribute to a circular economy in the mining industry.
