Recovery of copper from water by using a reactor of iron

In the article the way of recovery of copper ions from water using iron reactor and magnetic separator was presented. First, the copper was precipitated on iron plates when the water flowing through a reactor, then the precipitates were scraped mechanically using sandpaper and at the end, they were separated magnetically. The magnetic and non-magnetic products were digested and the concentration of chosen metals (Fe, Cu) were measured to assess the efficiency of copper recovery. The study was conducted for two solutions with initial pH 3 and 6. For them, the efficiency of copper recovery were 85% and 45%, respectively.
