INNOVATIVE HYDROMETALLURGY FOR GALVANIC SLUDGE SUSTAINABLE RECOVERY

Popis výsledku v původním jazyce

The manuscript explores the feasibility of recovering zinc and iron from waste galvanic sludge generated during galvanic plating processes. Galvanic sludge, characterized by elevated concentrations of heavy metals, represents a suitable candidate for hydrometallurgical recycling. The primary objective of the experimental and practical phases was to extract zinc and iron through the leaching of galvanic sludge. Leaching procedures were conducted using sulfuric acid at varying temperatures and time durations, augmented by the introduction of oxidizing agents such as hydrogen peroxide or ozone. Subsequent separation of the leach and filtrate was achieved through filtration. The leachate underwent additional processing involving the precipitation of iron and other metals, employing diverse agents. Following further filtration, electrolysis was employed to attain pure zinc on the cathode, utilizing an electrical voltage of approximately 3 V. Comprehensive chemical analyses were conducted on all intermediate products, including the leachate, leach liquor, filtrate, solid precipitate, and the separated metal on the cathode. The outcomes of these analyses are meticulously presented in tables and graphs.
