Abstract Scope |
As electrochemical systems for metal extraction scale up, transport phenomena become increasingly important for at least two reasons. First, larger dimensions unmask phenomena that were restricted by the walls of a small cell. Examples include natural convection and magnetohydrodynamic effects like “metal heave”. Second, scaling accompanies maturation of the process. Heat loss is neglected at lab scale with external heating, but is a key factor in the energy consumption at commercial scale.
Furthermore, sometimes these classes of phenomena intersect. Stability of the metal pad in Hall–Héroult limits the minimum anode-cathode distance, resulting in excess Joule heating. Improving the thermal efficiency would require improving the stability of the metal pad. This talk will focus on modeling tools and processes that can accelerate the scale-up of electrochemical metallurgical reactors from the bench-scale of a few amps to the scale pilot or small commercial scale of 10’s of kA. |
