Lead electrodeposition from aliphatic polyamines solutions

Abstract Hydrometallurgical and pyrometallurgical processing of ores concentrates generates large amount various solid residues. These may contain significant heavy metals, particularly lead is great importance. It present in form anglesite, cerrusite or oxides. leaching residues, dusts, fly ashes used to recover valuable metals from these streams. Acid sulfuric acid solutions spent electrolyte results producing high sulfate that still very attractive material fulfill demand battery market. Aliphatic linear polyamines are solvent extracting agents selective towards sulfate. Here we report the comparative tests four different aliphatic homologs, namely ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine as potential The core research was devoted possibility direct electrodeposition solutions. Electrochemical performed at current density 200 A/m 2 , 60 °C, with an addition selected inhibitor showed produce metal layer 97.2% purity for triethylenetetramine. Graphical abstract
