Description

Method for assorting electronic scrap [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an electronic scrap sorting method, and more particularly, to an electronic scrap sorting method capable of quickly and easily classifying electronic scrap according to oil price without consuming excessive time for accurate classification of electronic scrap.

Up to now, a process technology for concentrating and recovering valuable metals has been developed steadily from waste electronic scrap discharged from domestic computers, waste mobile phones, cameras, MP3, and other waste electronic devices.

It is known that waste electronic scrap discharged from various waste electronic devices generated in Korea contains not only precious metals such as Au, Ag and Pd but also valuable metals such as Cu, Fe, Sn, Ni, Zn and Pb.

Such waste electronic scrap has different treatment routes and methods depending on the source. Generally, the scrap of waste electrons generated in the manufacturing process is entrusted to the manufacturer by the manufacturer. In this case, scrap metal scrap generated after gold plating is sold by competitive bidding or number contract, and the disposal of the gold is recovered by the disposal company and final disposal is done such as incineration / landfill. In the case of waste electronic scrap generated before gold plating, copper was recovered by wet method, and incineration / landfill was finally disposed. Waste electronic scrap Approximately 32% of the total amount recovered by the recycler, local governments, and the electronics industry is collected and processed in the non-institutional areas such as small-sized commodities, assembled PC vendors, and specialized exporters.

Electronic scrap, which is processed through various routes and subjects, has an irrational problem because it is not easy to dispose of at an appropriate cost due to the relatively poor classification procedure, although accurate classification is necessary in disposal.

Particularly, in order to improve accuracy in the disposal of electronic scrap, it is necessary to invest a great amount of time, but the efficiency of the time-to-date sorting is remarkably reduced.

Therefore, there is a disadvantage that both the side to which the electronic scrap is transferred and the side to which it is transferred are not easy to dispose of the electronic scrap quickly and accurately.
