Integrated electronic waste recycling and recovery system and process of using same

Abstract

Systems and processes for recycling printed circuit boards, wherein precious metals may be reclaimed. The system generally includes a number of modules to systematically remove materials from the printed circuit boards and to separate the precious metals from the materials.

Description

technical field [0001] The present invention generally relates to systems and processes for recycling waste electrical and electronic equipment, such as printed circuit boards, to separate materials including, but not limited to, precious metals. Background technique [0002] As electronic devices become more ubiquitous, the disposal of old electronic devices, including obsolete or damaged computers, computer monitors, television receivers, cellular telephones, and the like, is growing rapidly. It should be recognized that when electronic equipment is dumped in landfills, there are often significant hazards to living things and to the environment. Likewise, it should be understood that improper disassembly of such equipment poses a significant risk to the health and safety of those performing manual disassembly. [0003] Printed circuit boards (PCBs) are common components of many electronic systems such as motherboards, laptop computer boards, TV boards, server boards, hard...
