ABSTRACT
The quick technological advancement induces era of utilized electric and electronic gear waste which is making a genuine danger the earth. Waste printed circuit boards (WPCBs), as the principle constituent of the waste, are source of base and precious metals particularly copper and gold. Printed circuit boards (PCBs) are as of now being dumped in landfills or burned which is bringing on a genuine ecological harm as toxic gasses or leached hazardous mixes. To recover these metals from waste has dependably been a test. The review here presents the most proficient strategy for recovering the base and precious metals; Electrowinning. Utilizing Electrowinning a setup has been intended for the recuperation of four unique metals. The review demonstrates the recycling of Gold, Silver, Copper and Palladium in proficient and immaculate form..
