Characterization of particle size-based deportment of metals in various waste printed circuit boards towards metal recovery

The particle size-based metal characterization of comminution fines of printed circuit board (PCB) of obsolete computer, laptop, and television (TV) was performed scoping towards the prioritization of target metals for efficient beneficiation. The metal characterization results revealed that the dis...
