1. A process for recovering lithium from a lithium source, the process comprising the steps of:
(a) precipitating at least one of calcium and magnesium from the lithium source in preparing a salt-containing solution comprising lithium ions and negative salt ions;
(b) receiving, in a membrane electrolysis cell, the salt-containing solution and a gas comprising O2; and
(c) delivering, from the membrane electrolysis cell, recovered lithium and reagent materials used in the process for recovering lithium,
wherein the lithium source comprises a brine, the salt-containing solution comprises LiCI, the recovered lithium comprises LiOH, and the reagent materials used in the process for recovering lithium comprise HCI.
