New technology for recovering residual metals from nonmetallic
Therefore, crushing is an essential process. The crushed fraction is treated with a corona electrostatic separator to separate the metallic and nonmetallic particles. However, the low separation efficiency of the corona electrostatic separation process for fine particles results in the detection of valuable metals in NMFs (Li et al., 2007b).
