The Cu–Pb–As–Zn mineralization of Cap Garonne (Le Pradet, Provence, France; Fig. 1) is located in Triassic siliciclastic rocks, a few meters above the contact between …
About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It …
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 …
Diverse opinions on the issues of South African mines' emissions, contamination and remediation have been summarized: environmental effects of heavy metal pollution from gold mines and …
The imbalance between raw materials of high economic importance and their supply has increased the search for new approaches to obtain valuable elements from mining …
