Recycling of waste printed circuit boards PCBs has attracted increasing attention because of its high annually produced amount and high content of gold In this study gold recovery from waste PCBs was carried out by using the processes including microwave pyrolysis acid leaching solvent extraction and oxidative precipitation The leaching efficiency
Recovery of copper metal from edge trim of printed circuit boards Printed circuit board edge trim has high copper content ranging from 25% to 60% as well as precious metal content > 3 ppm The process for recovery of copper and precious metals from printed circuit board edge trim is similar to that from waste printed circuit boards
Scrap PCB Printed Circuit Board Shredder Machine Description PCB Printed circuit board shredder is the very first machine to size reduce circuit board Its infeed opening should be big enough to process tons of circuit board at the same time During shearing and crushing of 2 rotors circuit boards are broken down into irregular pieces
At the heart of most electronic devices is the printed circuit board PCB This is used to support and connect electronic components using conductive pathways tracks or signal traces etched from copper sheets laminated onto a non conductive substrate The management of this e waste has become a hotly debated topic with the recycling of
The crushing performance of printed circuit board PCB was studied on several crushers The results show that PCB is a material which is difficult to crush The crushing performance of PCB with disk crusher especially vibration grinding which has cut or impact action excels that of jaw crusher or roller crusher The PCB scrap is worthwhile to recycle
