Abstract
The paper presents the results of laboratory studies of sulfuric acid leaching of copper and zinc from waste recycling stale. Considered intensification of leaching, which is made possible by the use of low concentration of acid-modified komplesonom natural origin – technical lignosulfonate (LST). This reagent is characterized by non-toxicity, selectivity, availability, while improving the quality and quantity with minimal impact on the environment.
Keywords
Leaching, technological waste, technical lignosulfonate, natural chelating.
