Abstract
The invention relates to a process for obtaining of highly dispersed copper and may be used in the industries, wherein there are formed wastes of copper etching used solutions, in particular in the production of printed circuit boards.Summary of the invention, according to the proposed process, consists in that it is carried out the electrolysis of the working solution and separation of the copper in the form of suspension, and in the capacity of working solution it is used the used solution of copper etching from the printed circuit boards, with copper ions concentration of 30…120 g/L. The process is conducted at the temperature of 20…25°C, the cathode current density being of 10…20 A/dm2, and the highly dispersed copper is removed from the cathode surface, which is preliminarily wetted with 0,5…1% solution of oleic acid in toluole.The device for realization of the said process contains a body with a cylindrical cathode, installed within it and concentrically placed anodes, pipes for inlet and outlet of the working solution, the cathode being made in the form of a hollow drum of stainless steel and situated in the upper part of the body with the possibility of rotation so that the upper part of the cathode be placed beyond the working volume of the body and provided with a device for dispersed copper removal from the cathode surface. The anodes are inclined placed under the cathode in the chambers with ion exchanging membranes, the upper parts of the chambers being brought outside the limits of the lateral walls of the body, the lower part is executed conic for sediment withdrawal and includes a circulating system, and in the upper part of the body it is disposed an indicator of the working and toluol solutions level.
