Incidence of Electric Field and Sulfuric Acid Concentration in Electrokinetic Remediation of Cobalt, Copper, and Nickel in Fresh Copper Mine Tailings

In the present study, assessment of heavy metal contaminant migration from fresh mine tailings was conducted using electrokinetic remediation technique (EKR). this sense, a pilot EKR cell designed to evaluate recovery potential copper, nickel, and cobalt species. particular, focus on impacts electric field intensity pH in initial mixture testing their interaction migration. Experiments were made 22 factorial experimental design with central point, DC fields 1.0 2.0 V cm−1 H2SO4 pretreatment solutions mol L−1, along an ANOVA test error reduction. The removal rates approximately 7% for cobalt, neglectable 6% nickel. best cases, highest concentrations by at cathodic zone 11%, 31%, 30%, respectively. According tests, factor proven each half near cathode closest specifically. Both factors affected concentrations, which indicates that when goal aims species accumulation narrower section, has significant effect, makes enhancement. Thus, L−1 showed high improvement concentration zone.
