Abstract
Mining activities are a key industry for many countries worldwide and especially
in Chile where production and exportation of copper is crucial for the country’s

increased concern to the communities due to dam failures or natural leaching to
groundwater and rivers. It seems to be of common interest that mine tailings
should be treated in some way to minimize environmental risks.
This work shows the laboratory results of three electrodialytic remediation
experiments on copper mine tailings. The results showed that an electric current
could remove copper. With the addition of sulphu
