Recovering Aluminum from Shredded Aluminum Electrolytic Capacitors by means of a Dry Shaking Table

抄録

Defective aluminum electrolytic capacitors at manufacturing processes are generally shredded to below 3 mm and buried in landfills. Shredded capacitors contain aluminum, nickel and non-metal materials such as rubber, plastics and fibers. Nickel particles are recovered by magnetic separation, but it is difficult to separate aluminum particle from non-metal materials. We have investigated the recovery of aluminum from shredded capacitors with a laboratory-scale dry shaking table that we developed.
