摘要: The generation of electrical and electronic waste is increasing day by day; recycling attractive because the metallic fraction containing these. Nevertheless, conventional techniques are highly polluting. comminution printed circuit boards followed an inverse flotation process a clean technique that allows one to separate from non-metallic fraction. It was found particle size superficial air velocity main variables in separation different fractions. In this way efficient achieved avoiding environmental contamination coupled with possible utilization fractions obtained.
