In this work, a continuous multistage electrodialytic technique is evaluated as a possible treatment of copper smelter wastewater. Six experiments with different values of feed flow rate, current density and treatment time were carried out. It was po

Electro-kinetic remediation (EKR) with sinusoidal electric field obtained simultaneously with DC/AC voltage reduce the polarization of the EKR with DC voltage. The DC voltage value defines the presence of a periodic polarity reversal of the cell and

In this paper, the electrodialysis technique is tested as a possible treatment of smelter wastewater containing mainly copper and arsenic. The results show that it is not feasible to treat the raw wastewater, because the highly acidic pH favours the

This work compares and evaluates the copper removal efficiency when applying electric fields to two mine tailings originating from the same mine but of different age. Eight experiments were carried out – four on tailings deposited more than 20 year

Due to the magnitude of the mining activity in Chile, it becomes necessary to find solutions to mitigate the impact of mining waste on the environment. One method that could be suitable for remediation of mining wastes is the use of electric fields f

Mining processes, prior to pyrometallurgical copper production, generate large amounts of solid waste, which are and have been deposited in mine tailings impoundments. This work is based on three electrodialytic (EDR) and four electrokinetic (EKR) re

An actual Chilean copper smelter wastewater treatment is a complex process that actually mostly is focused on fulfillment of threshold values more than sustainability. The actual wastewater treatment includes a number of precipitation, neutralization

Decades of mining activities in Chile have generated large amounts of solid waste, which have been deposited in mine tailing impoundments. These impoundments cause concern due to dam failures or natural leaching to groundwater and rivers. This work s
