“…The chemical composition of AMD depends on the mined rock mass and hydrogeology; they are typically characterized by acidic pH as low as 2, abundance of dissolved species, including sulfate, iron and other toxic metals (mainly lead, copper, cadmium, and arsenic) (Bejan & Bunce, 2015). Sulfate is usually found at high concentration (in the range of hundreds to thousands of mg L -1 ) from (di-)sulfide air/water oxidation and its water discharge regulation is becoming more stringent (Nariyan et al, 2018). In parallel, ferric hydroxide (Fe(OH)3) precipitation is another environmental issue.…”

This review proposes an insight into the prospects of electrochemistry for the treatment of highly concentrated effluents in three sections. The first section focuses on the challenges inherent to such kind of wastewater, divided into five categories: industrial wastewater (e.g., pharmaceutical, electronics, chemical, food-processing), hypersaline effluents (e.g., RO concentrates), solutions contaminated with a mixture of organic and inorganic contaminants (e.g., leachate, mining), highly viscous solution (or non-Newtonian liquid) (e.g., sludge) and solutions of high COD load but with low pollutant content (e.g., from soil washing). The second section of this review then focuses on the treatment strategies to ensure that the electrochemical treatment is adapted to these very specific waste streams, including the influence of operating conditions, electrode materials and processes (with special emphasis on anodic oxidation, electro-Fenton and electrocoagulation). The final part focuses on the perspectives of electrochemical treatment of challenging wastewater, by giving the engineering parameters to ensure successful upscaling of electrochemical processes in terms of modeling mass transport, charge transfer and hydrodynamics, reactor designs and energy requirements. The review concludes on process combinations, where electrochemistry could complement traditional methods of treatment, in order to improve the overall efficiency of the integrated system.

“…The elevated sulfate concentration in natural water is an indication of water deterioration [14]. Additionally, the sources, transportation, and transformation of the sulfate contaminates can be determined by analyzing the isotope compositions of sulfur and oxygen in sulfate anion [15][16][17][18][19]. Moreover, water-rock interactions have a strong influence on the chemical characteristics of water bodies [20][21][22].…”

Antimony (Sb) is a versatile metal element and has found applications in flame retardants, batteries, solar cells, and semiconductor industries. The increasingly widespread usage of Sb has caused environmental pollution. Recently, Sb has been detected in soil, water, river sediment, plants, and groundwater-especially in areas around Sb mines [1]. The Xikuangshan Mine in Hunan, China, known as the world's antimony capital [2], currently accounts for 90% of the world's total antimony ore production [3]. Numerous studies have been carried out in this area to evaluate the multimedia environmental pollution caused by Sb [4-6]. The Qingfeng and Xuanshan rivers, two main tributaries of the Zijiang River, have already been heavily polluted

“…Their study showed that about 100% Al, 100% Cu, 90% Si, 100% Zn, 30% Mn and 30% SO4 2-were obtained with iron electrode at 70 mA/cm 2 current density for 120 min reaction time and about 80% Fe, 100% Cu, 100% Si, 40% Zn, 20% Mn and 40% SO4 2with aluminum electrode at the same experimental conditions. Nariyan et al (2018) also studied of precipitation with lime plus electrocoagulation for sulfate removal from Pyhäsalmi mine water. Sulfate concentration was decreased from 13,000 mg/L to 1600 mg/L with calcium oxide (lime).…”

A large amount of mining waste occures due to the intensive mining activities in our country. These wastes may contain different pollutants depending on the type of mining facilities. The lead-zinc-copper flotation waste was investigated in this study contains significantly calcium, iron, magnesium and sulfur elements. The presence of high concentrations of these elements has an environmental problem. For this reason, in this article, firstly, the mine waste was obtained from the Gümüştaş Mining Corporation, the Lead-Zinc-Copper Enhancement Plant. Then, characterization and iron and sulphate removal experiments were investigated under different inorganic acids. Experimental studies showed that about 30% iron and 85% sulphate removal yields were obtained with 4 M HCl concentration.
