Regardless of dry milling or wet milling, the RLRs of Pb and Ni decrease continuously with an increase in milling time. For Cu and Cr, the RLRs reached 17.27% and 15.08% after 2 h of dry milling, and the RLRs reached 17.03% and 18.97% after 2 h of wet milling. Prolonging the ball milling time cannot further reduce the RLRs of Cu and Cr.
