The engineering properties of tailings are important for the safety evaluation and engineering design of tailing dams. In the present study, laboratory experiments were performed to investigate the geotechnical properties of four different tailings, including two iron tailings (coarse and fine) and two copper tailings (coarse and fine).
Underestimated environmental benefits of tailings resource …
In this paper, we selected copper tailings as a representative case study. First, we used material flow analysis for copper tailings in Tongling City and then constructed a life cycle assessment model. Finally, we set up a detailed scenario analysis of the carbon reduction benefits of copper tailings resource utilization.
Take two: why mine tailings are worth another look
Tailings as a source of minerals and metals. But what's this got to do with tailings? Well, put simply, the production of more metals will generate a lot more waste. For example, according to the IEA, the average copper ore grade in Chile – the world's largest copper producer – in 2019, was 0.7% (see figure 1). That means that, for ...
