Recovery Of Copper From Copper Ash By Electrostatic Method China Platre Fabrication

The printed circuit board PCB contains nearly 28 metals that are abundant non-ferrous metals such as Cu Al Sn etc. The purity of precious metals in PCBs is more than 10 times higher than that of rich-content minerals. Therefore recycling of PCBs is an important subject not only from the treatment of waste but also from the recovery of valuable materials. Chemical and mechanical methods .

Bottom ash is collected in a quench pit beneath the burnout section of the grate. Fly ash is the solid and condensable vapor-phase matter that leaves the furnace chamber suspended in combustion gases and is later collected in APCDs. The APCDs in use since the middle 1980s capture a high percentage of the contaminants in the flue-gas stream.
