Abstract
In this work we demonstrate the validity of a multi-physics model using COMSOL to predict the local current density distribution at the cathode of a copper electrowinning test cell. Important developments utilizing Euler-Euler bubbly flow with coupled Nernst-Planck transport equations allow additional insights into deposit characteristics and topographies.

All tests with the exception of the straight cathode were run to a period of short circuiting with the anode
Summary
University of Utah Right click to open a feedback form in a new tab to let us know how this document benefits you. Electrowinning is the electrochemical process of depositing metal from dissolved metal ions without replacement of metal ions via anodic dissolution This is an important method for a variety of primary and secondary metals processing scenarios. This paper describes the fundamental methods of finite element analysis to determine the average thickness of a deposit in an electrowinning cell utilizing a multi-physics approach. The objectives of this approach are to facilitate the accurate prediction of local current density and the average cathodic thickness. To better understand the multi-physics nature of electrowinning systems Figure 1 of a copper system is provided This schematic representation of a single anode cathode pair shows the major influences of the system. Migration and bulk species transport combine to describe the movement and concentration of species of interest
