“…Electrocatalysis-Fenton oxidation and photocatalysis-Fenton oxidation are generally used as combined processes. Yang et al [163] found that ethyl xanthate was effectively degraded using bismuth ferrites based on activated bentonite (A-BiFe/Bent in Table 9) as particle electrodes in a three-dimensional electro-Fenton system under visible light. At Na 2 SO 4 concentration of 0.10 mol/L, a concentration of bismuth ferrites based on activated bentonite of 1.0 g/L, an applied voltage of 10 V, an aeration intensity of 3.5 L/min, and at natural pH, the ethyl xanthate degradation efficiency and COD Cr removal efficiency were 97.85% and 93.50%, respectively.…”

Water used by mining enterprises needs to be comprehensively recovered and utilized to achieve clean production. This requires the effective treatment of mineral processing wastewater. Wastewater produced during non-ferrous metal mineral processing contains a complex mixture of pollutants at high concentrations, making comprehensive treatment difficult. Here, the sources of and hazards posed by wastewater produced during non-ferrous metal mineral processing are introduced and the techniques for removing heavy metal ions and organic chemicals are reviewed. Chemical precipitation and adsorption methods are often used to remove heavy metal ions. Chemical precipitation methods can be divided into hydroxide and sulfide precipitation methods. Organic chemicals are mainly removed using oxidation methods, including electrochemical oxidation, photocatalytic oxidation, and ultrasonic synergistic oxidation. External and internal cyclic utilization methods for treating wastewater produced by mineral processing plants are introduced, and a feasibility analysis is performed.
