Využití hydrometalurgických metod k získávání ušlechtilých kovů z elektroodpadu

Abstract

Thesis deals leaching from electric, to regain precious metals. Specifically, copper and tin, which are represented in the metals most printed circuit. It is divided into two parts. The theoretical part is devoted to the characterization in terms of its electrical hydrometallurgical processing and recycling description of technologies used in the processing of electronic waste. The experimental part is devoted to chemical leaching circuit board in an acid environment, particularly in solutions of sulfuric acid, nitric acid and hydrochloric acid. Also, non-standard leach - thiourea solution. After leaching electrolysis was used for extraction of metals from the leachate. The aim was to determine what solution is best suited for a given metal.
