摘要

The present invention provides a process for the recovery of gold metal from manually dismantled gold coated E-Waste. E-waste is of the printed circuit boards; using organic acid. Acetic acid with sodium chloride is used as an organic acid. Hydrogen peroxide is added drop wise into the reaction mixture for the recovery of gold metal. Recovery of more than 99%) and purity of 99% of gold metal along with iron recovery of more than 99% is feasible. Small amount of copper dissolved into the reaction mixture is enough for the gold recovery.
