- Duoling Lead Zinc Copper Golf Mine Impact
Globally, the amounts of metal ore deposits have been declining, so the research directions investigating the extraction of metals from materials that are classified as waste are gaining more importance every year. High concentrations of Cu, Pb, Zn, and Fe were analyzed in the sludge sediment (Zlaté Hory, Czech Republic), which is a waste …

To address this problem, a novel and efficient in-situ encapsulated approach was proposed in this study. A biocemented lead-zinc tailing backfill (BPTB) was prepared by mixing cement, microbial solution, lead-zinc tailings, and water, with the aim of reducing the leaching behavior of lead-zinc and achieving environmentally friendly backfilling.
