Vortex electrowinning is an electrowinning technology developed by one of the founders of Electrometals Mining (later to become emew Corporation) trying to develop an efficient copper powder production method.  It was discovered that there were very significant improvements in metal recovery rates and selectivity as a result of the high flow rate and vortex design enhancing mass transfer in the cell. In contrast, traditional electrowinning involves placing an anode and cathode in a bath of slowly circulating or stagnant electrolyte, where metal ions gradually diffuse to the cathode surface for plating.
