Extraction of Au(III) Using Aromatic Ketones in Acidic Chloride Media

Recently, the extraction of Au(III) using series aliphatic ketones in hydrochloric acid media has been investigated detail. The present study describes behaviors a aromatic ketones, which never reported. Aromatic with shorter alkyl side chains showed higher extractability. rapid and capacity were comparable to industrial extractant dibutyl carbitol (DBC). except acetophenone, are less soluble water than DBC. flash points satisfactorily high for operation, but their specific gravities that unwelcome. Butyrophenone selectively extracted from many other metals, Fe(III) Ga(III) at concentrations. butyrophenone recovered quantitatively as metallic gold by reduction oxalic acid.
