In electronic appliances, printed circuit boards PCB represent an important component, containing high grade of valuable metals, besides organic resins and some ceramic materials. Copper is the major metal in PBCs composition normally higher than 20 ww but many other secondary and minor metal elements, including precious metals, are found in PCBs.
Printed circuit boards PCBs contain many toxic substances as well as valuable metals, e.g., lead Pb and tin Sn. In this study, a novel technology, named supergravity, was used to separate different mass ratios of Pb and Sn from Pb-Sn alloys in PCBs. In a supergravity field, the liquid metal phase can permeate from solid particles. Hence, temperatures of 200, 280, and 400 were chosen ...
