In this work an electrokinetic remediation cell for copper mine tailings using sinusoidal electric field was analyzed. The sinusoidal electric field was obtained by applying simultaneously continuous-alternating voltages; in this work an alternating voltage of high frequency was applied. The system was tested considering the effect of: (1) the effective voltage applied to the cell and (2) the polarity reversal of the cell. According to the conditions studied in this investigation, the laboratory results showed that a high frequency sinusoidal electric field improves the EKR process, and increasing the effective voltage improves the remediation action, especially when a polarity inversion is present, which reduces polarization during the process.
► High frequency sinusoidal electric field improves the EKR process. ► Higher effective voltage increases copper removal. ► Removal from the cell is increased as time ratio for polarity increases. ► DC voltage of 15.3 [V] and AC voltage of 23 [V] are promising conditions.
