However, it is unclear whether the conventional approach for Cu-Zn and Cu-Zn-Pb ores (i.e., depression of sphalerite using zinc sulfate) is effective in Cu/Zn separation in the processing of the copper ores excavated from PCDs with a much lower level of Zn (e.g., a Cu/Zn ratio of 7:1 (w / w)) compared to Cu-Zn or Cu-Zn-Pb sulfide ores . Thus ...

From the Middle Ages until the beginning of the twentieth century, extensive Zn–Pb mining and smelting was carried out in East-Belgium. By lack of waste treatment techniques and sustainable management practices, metal-bearing slags and unprocessed waste were dumped in huge tailings, which still represent an important source of contamination. A …

In mineral processing operations, besides target minerals, slurries often contain various metal ions, including common ones with different valence states such as Pb 2+, Cu 2+, Fe 2+, and Fe 3+.These metal ions originate from multiple sources during the flotation process, including the dissolution of co-occurring metal minerals during crushing and grinding, the …

Garnet is the most common alteration mineral in skarn-type deposits, and the geochronological research on it can limit the mineralization age. The Longwan Pb–Zn deposit, situated within the Fozichong Pb–Zn ore field in Guangxi, lacks precise geochronological data, limiting the in-depth comprehension of its genesis and tectonic setting.

Consequently, the degree to which a metal, mineral or material is considered critical, is determined by geopolitical factors that change with time (Spooren et al., 2020).For example, Australia has 24 "critical minerals" (Austrade, 2020) compared to the EU's 30 "critical raw materials" (European Commission, 2020).The EU has also seen an increase in the …
