Lead is produced from ores, and it occurs in the form of various minerals; galena (PbS) is the most common ore of lead and zinc. Other minerals are anglesite (PbSO 4) and cerussite (PbCO 3).Galena is associated with ZnS, FeS, Cu 2 S, SiO 2, other impurities (Bi, As, Sb) sulphides and precious metals (mainly Ag).Ores are generally of a …

Reduced soil quality: High concentrations of lead in soil can also reduce soil quality and fertility, making it more difficult to grow crops over time. To mitigate these …

The above-mentioned mineralogy results in concentrate quality at above ~60% copper content. Finally, the copper rich minerals include significantly less iron, which drives a quality challenge at the process plant. Mines could slow down the gradual grade decline by removing a larger proportion of iron and gangue content from the concentrate.
