    Abstract

    Hydrogen gas diffusion anodes (HGDA) have been considered previously as alternatives to oxygen-evolving lead alloy anodes in metal electrowinning. Despite their higher capital costs, the substantial decrease in electrowinning production costs potentially offered by HGDAs is causing renewed interest in their industrial use. This paper reviews the more recent applications of hydrogen gas diffusion anodes in industrial electrowinning. Using data from the literature, a simplified economical assessment is presented for a zinc electrowinning tank house implementing hydrogen gas diffusion anodes; optimum operating current densities of about 3 kA m-2 are predicted.
