Abstract:
1. A method for maintaining a concentration range of an electroreducible metal species during electrolysis, comprising: containing in a first container a first body of a solution including dissolved metal; maintaining a second body of the solution in a second container, the dissolved metal of the second body having a concentration; isolating the second container from the first container; circulating the second body at a turbulent flow velocity through an electrolyzer in a first circulation loop; electrolyzing a portion of the dissolved metal of the second body in the electrolyzer; sensing the concentration; and responsive to the sensed concentration, opening one or more flow paths between the second container and the first container, and circulating a portion of the first body and a portion of the second body at a turbulent flow velocity through the electrolyzer in a second circulation loop.
