ABSTRACT The waste electronic circuit contains a lot of metal and is a kind of waste disruptible causing environmental pollution. Our research has found a way to separate and recover metal copper to treat a part of solid waste is the circuit board. The results of this study include the choice of copper binder from Fe2(SO4)3, the copper extraction efficiency is quite high. Other way, using iron shavings we have completely recovered the amount of copper has split, the purity of copper metal reached about 90%. The proposed metal-to-metal separation and recovery process ensures the safety of the environment. Keywords: Metal recoverry; collect copper; electronic ciruit boar. |
