Fourteen printed circuits were disintegrated and combusted in fluidized-sand quartz reactor (diam. 96 mm, height 400 mm) fired with PrH-PrMe mixts. The combustion gases were analyzed for O(2), NO, NO(2), SO(2), CO, CO(2) and volatile org. compds. The solid residues were analyzed for 11 metals after extn. with concd. KOH and H(2)SO(4) solns. High recovery degree (from 90.56% for Ti up to 99.96 for Ni) was achieved.
