Gold recovery from printed circuit boards. A typical PCB comprises 40% metals, 30% plastics and 30% ceramics, 5,10 with the metal fraction comprising 10–27% Cu, 2–8% Al, 1–4% Pb, 1–8% Fe, 1–6% Sn, 0.2–3.6% Ni, 0.1–1.5% Zn and <0.1% precious metals. 25–30 These data were typically obtained by milling the waste PCBs and then …
Abstract. Printed circuit heat exchanger (PCHE) is a promising candidate of coolers used for SCO 2 Brayton cycle. The thermal-hydraulic performance of SCO 2 in a PCHE depends on the PCHE structure as well as the operating conditions of SCO 2 due to its dramatic variation of thermal physical properties near the pseudo-critical point. This …
