Patent ID: 8220729

Claim:
A recycling process to regain re-usable raw material and avoiding escape of noxious stuff for electronic waste comprising the following steps: a. conducting a first sorting step involving separating all evidently noxious material containing construction components in a closed room, b. comminuting a mixture of remaining materials by a smasher, c. conducting a second sorting step in a closed room involving separating noxious stuff containing material from not contaminated material, d. separating ferro-magnetic material by using a magnetic system, e. conducting a third sorting step involving separating bulky material and such of big volume, f. conducting a second comminuting step of material already released from noxious material by using cutting equipment, g. conducting a flotation process by using a water bath having a controllable vibration equipped with a adjustable pulsator for separating plastics from material heavier than plastics, h. conducting an additional flotation process being equipped with controllable vibration of the bath of separation liquid for separating plastics of different density, i. conducting an identification and determination of such plastics regained followed by a packaging and marking step in correspondence to individual identity, j. conducting a follow-up treatment of the material heavier than plastics by a separation equipment to sort out non-iron stuff from residues as stones and similar objects by a procedure based on inductive or magnetic measures, k. separating non-iron material by a sorting equipment that differentiates Al, Ni, Cr, Ag, Au etc, from each other, and l. taking residues to a slagheap or a thermal disposal site.
