The metallic contents of the minerals are recovered from the …
Therefore, pyrite is a common by-product with low economic value in most sulfide mineral processing plants. The feasibility of utilizing pyrite to degrade other organic contaminants in aqueous solution has been previously studied and established (Guo et al., 2021, Pham and Chihiro, 2019, Pham et al., 2008). As such, the treatment of …
AMD also occurred in the region involved with anthropogenic activities such as highway construction, large-scale excavations, galvanic processing, and the scrubbing of flue gases at power plants . In the mining process, the sources of AMD include: Tailing deposits. Spoil piles from coal mines. Waste rock dumps from metal mines
