1. A method for producing one or more hydroxide solids, the method comprising:
providing:
a basic catholyte solution comprising an electrolyte;
an acidic anolyte solution; and
a neutralization pool comprising an alkaline material;
contacting the basic catholyte solution with a cathode to electrolytically generate hydroxide ions, thereby precipitating the one or more hydroxide solids; and
circulating the acidic anolyte solution into the neutralization pool, thereby forming a neutral anolyte solution.
