An airstream solid sorting technology easily and efficiently sorts electric wire and other slender objects from other unslender objects in crushed bulk wastes. A mixture of slender and unslender objects is supplied into an airstream sorting vessel, in which a turbulent stream of gas supplied from below through a meshed screen tilted in its bottom agitates the mixture. Slender objects stalling and falling longitudinally in the direction in which gravity works pass through the meshed screen, thus falling into a slender objects collecting vessel placed below the meshed screen. Unslender objects sliding down along the tilted meshed screen are thus separated.
