Separation of copper from telephone cables by gravity concentration

Waste electric and electronic equipment (WEEE) has the fastest growth compared to other types of waste due to the amount and thus increasing the need for its care about it. Disposal at landfills is not desired by the fact that this type of waste contains a number of useful materials that can be used again, as well as dangerous substances for which disposal is not desirable. This paper presents laboratory tests of separating copper from telephone (UTP and STP) cables that are an integral part of electronic equipment. Testing were carried out by method of gravity concentration using Wilfley shaking table and Humphreys spiral concentrator. The results showed that these devices can be used successfully to obtain copper concentrate whereby better results were obtained at a shaking table.
