4. Becoming non-metallic fractions
The nature of the materials used to manufacture electronic cards depends on their use. Two commonly encountered compositions are epoxy resin-reinforced fiberglass and phenolic resin-reinforced cellulose paper.
Xu's group describes the preparation of a plate from non-metallic residues from printed circuit boards . First, the electronic cards are crushed, then the copper fraction is separated by electrostatic sorting. The non-metallic fractions...
