Regionalized Life Cycle Inventories of Global Sulfidic

2022年3月16日  Worldwide, an issue of copper production is the generation of mine waste with varying characteristics. This waste can pollute natural environments, and in particular, the heavy metal emissions of the tailings may pose long-term consequences. Currently, life cycle assessments of mine tailings are hampered by both limited data availability in the

The tailings is the finely ground waste product (which generally represents more than 98 percent of the original copper ore) suspended in a water-based slurry that is emplaced in a tailings storage facility (TSF). Water is required for many activities at a mine-mill site, including ore production and

Frontiers Strength variation characteristics of waste

2023年4月5日  The ore body of the copper and iron mine analyzed in this study is at a great depth and is relatively scattered, but the total ore reserves are considerable. The ore-bearing rocks are relatively broken due to geological and structural factors, thus leading to the technical problem of the surrounding rocks and roof plate frequently collapsing
