1. A method for processing electronic and electrical device component scrap, comprising sorting electronic and electrical device component scrap by wind power sorting to remove plate-shaped objects containing valuable metals from the electronic and electrical device component scrap, and then sorting resulting sorted objects by magnetic sorting,
wherein the plate-shaped objects are sorted by using a wind power sorter comprising;
a diffusion chamber which diffuses the plate-shaped objects therein using an air flow;
a blower which generates the air flow in the diffusion chamber;
a feed portion which feeds the electronic and electrical device component scrap into the diffusion chamber while vibrating the scrap; and
a guide portion extending into the diffusion chamber from a terminal of the feed portion, the guide portion having a comb shape and comprising a plurality of protruding portions having a space therebetween, a width of the space being formed to be uniform from the terminal of the feed portion to a feeding direction, and the guide portion being arranged such that the air flow is brought into uniform contact with the plate-shaped objects from lower surfaces of the plate-shaped objects in a perpendicular direction to the lower surfaces of the plate-shaped objects.
