Precious Metal Refining & Recycling System for E-waste

E-waste precious metal refining system is designed to refine and recover precious metals like gold, silver, palladium (Pd) and platinum (Pt) from electronic waste (e-waste) like circuit boards, including CPU, RAM, pins, and other computer components. E-waste is classified as hazardous material therefore should be managed properly.
