TREATMENT METHOD FOR RECYCLING WASTE OF OFFICE AUTOMATION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To efficiently recover valuable metals, such as iron, stainless steel or aluminum by sorting the same. SOLUTION: This treatment method comprises steps of conducting a first magnetic sorting wherein a waste containing metals is pulverized to sort the same into an iron scrap and other scraps, conducting a second magnetic sorting wherein aluminum type metals are screened among other scraps by stronger magnetic force than that of the first magnetic sorting, and conducting a third magnetic sorting wherein stainless steel type metals are screened among the remained scraps by a stronger magnetic force than that of the second magnetic screening.
