electrodecantation (or electrophoresis convection) 

https://doi.org/10.1351/goldbook.E01950
Electrodialysis may lead to local differences in concentration and density. Under the influence of gravity these density differences lead to large scale separation of sols of high and of low (often vanishingly low) concentrations. This process is called electrodecantation.
