method of enrichment on table concentrator of crushed elements of scrap of radio-electronic equipment

摘要

The invention relates to enriching technology of preparation of the crushed elements of radio-electronic equipment for pyro- and hydrometallurgical processes. A method of enrichment on a table concentrator of crushed elements of a scrap of radio-electronic equipment includes supply of raw material and water to an oscillating deck and removal of concentrate from it. In accordance with the invention, the frequency of deck oscillation of 12.3-13.15 s(740-790 min) with amplitude of 2.5-2 mm is created. The invention provides for increase of the separation efficiency of the crushed mixture of the elements of scrap of radio-electronic equipment, possibility of processing the raw material with upper limit of coarseness up to 6-10 mm.
