RESEARCH METHOD OF RECYCLING METHODS FROM EMPHASIZE WASTES WITH ENVIRONMENTAL EFFICIENCY

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.
