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 …
Furnace slag and M. sinensis reduced CaCl2-extractable heavy metals by 56-91%, red mud and P. aquilinum treatment was the most effective at decreasing bioaccessible Pb, reducing it to 34% of the total Pb. Compared to control, water soluble Cd, Cu, Pb, and Zn were reduced by 99, 99, 98, and 99%, respectively, in the red mud and …
After ball milling, the leaching concentrations of Pb, Cu, and Zn were reduced to 0.027 mg L − 1, 0.59 mg L − 1, and 0.16 mg L − 1, respectively, and their pH …
The application of SR and SC and plant growth both facilitated the aggregate formation and the stability of Cu/Pb-Zn tailings. Plant roots played an important role in tailings remediation, which benefited from its effectiveness in promoting aggregate stability, OM accumulation, and microbial activity. Organic matter anion groups, which …
The use of Zn dates back to ancient times. As early 8000 B.C., an alloy of Zn-Cu and other Zn compounds were used by Romans, Greeks, especially for the production of brass. ...
