“…The presence of sulfur minerals, mainly pyrite (FeS 2 ), exposed to an atmosphere rich in oxygen, water (such as humidity, rainwater, surface or underground water), and microorganisms favor oxidation. The oxidation of sulfur minerals by anthropic activities is the primary source of AMD generation (Kalyoncu-Ergüler 2015). AMD has the following characteristics: (i) pH values < 4, (ii) high potentially toxic heavy metals and metalloids (PTHMM) concentrations, and (iii) high levels of sulfates.…”

“…AMD has the following characteristics: (i) pH values < 4, (ii) high potentially toxic heavy metals and metalloids (PTHMM) concentrations, and (iii) high levels of sulfates. When the AMD reaches the water reservoirs, water quality is affected negatively as well as the health of the different ecosystems that inhabit or consume it (Park et al 2007, Espinosa-Rodríguez et al 2010, Kalyoncu-Ergüler 2015, Vélez-Pérez et al 2020. As a consequence of AMD dispersion in mining areas, PTHMM are usually found in water reservoirs because they are soluble in acid conditions and non-biodegradable.…”

“…However, this neutralizing effect is inhibited during long interaction periods or by the generation of large amounts of AMD (Bai et al 2009, Muliwa et al 2018. Rice husks and green algae (Dipak et al 1993), shrimp shells (Cho 1994), oak sawdust (Yu et al 2000), basalt slag (Nugteren et al 2002), crab shells (Lee et al 2004), coconut shell (Amuda et al 2007), and eggshell (ES) (Park et al 2007, Kalyoncu-Ergüler 2015, Zhang et al 2017) are some natural materials that have been evaluated to treat AMD and prevent environmental deterioration. Most of these materials are considered waste.…”

Acid mine drainage (AMD) is a source of soil and water resources pollution. Calcite is a mineral constituted of calcium carbonate (CaCO3). The AMD interaction with calcite drives their natural neutralization. Calcite is the main component of the chicken eggshell (ES). This work aimed to evaluate the use of ES waste as a material to treat raw AMD. Five treatments (T1, T2, T3, T4, and T5) were carried out with concentrations of 1, 2, 3, 4, and 5 ES g/L AMD, respectively. Each treatment was performed for 3 h at room temperature without agitation. The response variables analyzed were pH, redox potential (Eh), electrical conductivity (σ), chlorides (Cl–), alkalinity, sulfates (SO42–), nitrates (NO3–, and potentially toxic heavy metals and metalloids (PTHMM). Also, the removal efficiencies of SO42–, NO3–, and PTHMM were analyzed. Additionally, the chemical and mineralogical composition of ES and precipitates were determined. The initial pH for AMD was 2.50 and it reached a final value of 5.50, 5.60, 5.80, 5.93, and 6.12 in T1, T2, T3, T4 and, T5, respectively. Moreover, the different treatments granted alkalinity to the treated effluents, reaching a maximum value of 124 CaCO3 mg/L in T5. Finally, Al and Fe were completely removed from AMD, whereas Cu reached > 95 % removal, especially in T3, T4, and T5. Ba, Cr, and Pb showed an average removal of ~65 %. The ES concentration that showed the best results of neutralization and PTHMM removal efficiency was 5 ES g/L. The results showed that ES is a biocompatible waste material with an added value because it can be used as a sustainable material to treat raw AMD.

“…These dyes are non-biodegradable due to their toxic nature [2], the elimination of pollutants and colored effluents from wastewater is important for protecting public health and the environment [3]. There are many traditional techniques applied in the dye removal such as coagulation, flocculation, photo degradation, sedimentation [4], ion exchange, and membrane filter processes such as micro-and ultra-filtration and reverse osmosis. These methods are expensive, use chemical products and generate large amounts of sludge [5].…”

Cellulose acetate hollow fiber membrane from banana stem fibers coated by TiO2 (CAHFMT) was prepared and characterized as an alternative material for degradation of waste textile dye. Its applicability was demonstrated by mechanical properties, FTIR, SEM, thermal resistance, performance, and degradation efficiency. Cellulose acetate (CA) was synthesized from banana stem fibers by swelling stage, acetylation reaction, and hydrolysis reaction. CA was modified using TiO2 of various concentrations. CAHFMT with 22 % w/v dope concentration has the optimum mechanical properties (stress, strain and Young’s modulus), as well as hydrophilic properties. The performances of CAHFMT with Congo red were determined. The SEM results showed that the membrane had rigid pores. Moreover, this research stated that CAHFMT could be a solution to overcome economical and effective problems.

“…The waste sludge generated from wet scrubbing of basic oxygen furnaces in steel-making plants was examined as a novel adsorbent for removing manganese, copper, iron, and zinc from actual AMD in Wheal Jane mine, Cornwall, UK(Jafaripour et al, 2015). It was found that about 100% of Cu and Fe, 97% of Zn and 94% of Mn were removed from AMD, demonstrating the waste sludge had a great potential as an alternative material for AMD treatment.Laboratory experiments were conducted to study the use of eggshell for the treatment of a contaminated mining site in the abandoned Can lignite basin in northwest Turkey(Kalyoncu Erguler, 2015). Samples of acidic water and solids were collected from acidic ponds and waste deposits.…”

This review provides a snapshot of papers published in 2015 relevant to the topic of mine drainage generation and control options. The review is broken into 3 sections: Generation, Prediction and Prevention, and Treatment Options. The first section, mine drainage generation, focuses on the characterization of mine drainage and the environmental impacts. As such, it is broken into three subsections focused on microbiological characterization, physiochemical characterization, and environmental impacts. The second section of the review is divided into two subsections focused on either the prediction or prevention of acid mine drainage. The final section focuses on treatment options for mine drainage and waste sludge. The third section contains subsections on passive treatment, biological treatment, physiochemical treatment, and a new subsection on beneficial uses for mine drainage and treatment wastes.
