Bioaccumulation of lead (Pb) and its effects in plants: A review
The lead (Pb) is one of the most common heavy metal contaminants in soils. Plants are exceedingly harmful to it (Zeng et al., 2007).Pb has no biological purpose in plants, although it can create morphological, physiological, and biochemical problems (Zeng et al., 2007, Kumar et al., 2017).A soil lead hazard is defined by the Environmental Protection Agency (EPA) as bare …

Pb-Zn Mineral Processing
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 is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this category.
