“…In the mining sector for metal production, the most crucial factors are pH, the heavy metals concentration, and dissolved anion concentration, i.e., sulfate, chlorides, arsenates, nitrates, etc., and hardness as well as suspended solids. For a better characterization of AMD as well as the properties of waste which are affected by AMD is summarized into five common features listed as follows [3].…”

“…The value of 650 NTU of turbidity indicated the presence of high quantity of dyes, pigments and colloidal substances (Hongve & Åkesson, 1996;Guaratini & Zanoni, 2000;Carmen & Daniela, 2012;Ghaly et al, 2014;Chandran, 2016). High colored effluents were seen to affect the visual appearance of water bodies, influence the rate of photosynthesis and, in extreme cases, cause the eutrophication of aquatic ecosystems (Pierce, 1994;Beltrame, 2000;Sarayu & Sandhya, 2012;Favas et al, 2016;Gómez et al, 2017). The quantity of 1.0 mg L -1 of settleable, 395 mg L -1 of suspend, 6395 mg L -1 of dissolved and 6790 mg L -1 of total solids, indicated the presence of high quantities of yarns and lint that were released from the fibers, as much as the presence of substances like salts, alkalis and acids that were used in the textile processing (Correia et al, 1994;Ghaly et al, 2014;Chandran, 2016).…”

According to reports, if released in excess, those solids may affect the oxygenation of water bodies, decrease the photosynthesis rate and cause negative effects on aquatic ecosystems (Dey & Islam, 2015;Favas et al, 2016). The BOD5 value of 1747 mg L -1 , COD a value of 3595 m L -1 and ISSN 2327-0640 2020 BOD/COD ratio of 0.49 indicated a mean presence of non-biodegradable organic matter.…”

“…One of the primary concerns for opponents to copper-nickel-precious metal mining is the potential threat of acid mine drainage. When sulfide minerals (i.e., pyrite) are exposed to oxygen, water, and bacteria (weathering), they generate acidic environments [48,49] through the production of sulfuric acid [50]. Once this sulfuric solution is released into the environment, it often leeches heavy metals from rocks.…”
