摘要： The invention relates to a method for processing electronic wastes, characterized that: . a/ grist is prepared from electronic wastes containing metals too, and the grist is heated in a reactor, preferable at 455-465 °C temperature, the vapours of the soldering metals exiting over 200 °C are lead away, precipitated with cooling, the soldering metals are recovered, the gas generated in the reactor is lead into an alkaline quencher, where it is purified, the coal portion of the heating residue remaining on the bottom of the reactor is lead away, and the polymer heating residue is treated with acidic solution, or . b/ the metals are removed from the surface of the surface of the electronic waste to be processed with rubbing-grinding, separation of the copper, nickel and noble metals is carried out with a known method, electrically, this way dischargeable melt is obtained, at higher temperature the lead-containing soldering metals are recovered as secondary melt, the metals are separated, and the light fraction is crushed, the resin is heated in a low temperature reactor, in order to recover the resin, the vapours generated are lead away, cooled, the solidified resin is recovered, the bottom product of the reactor is treated with nitric acid, and the solid residue is separated. . The equipment of the invention is characterized that inside its feeding screw (14) there is a plate lock (13), the central unit of the reactor is the bearing box of the driving engine (15), containing double stuffing box (26, 27, 28 and 29), and the lower part of its stirring mechanics is an anchor stirrer, has dredging shovels (5), on the conoidal frustum shaped bottom of the reactor there is a removal hole, closed by a cone lock (6), and the removal hole continues in a vertical neck (10).
