1. An ion exchange reactor for generating a lithium eluate solution from a liquid resource, comprising:
a) a tank;
b) ion exchange particles that selectively absorb lithium from said liquid resource and elute said lithium eluate solution when treated with an acid solution after absorbing lithium from said liquid resource;
c) one or more particle traps; and
d) provision to modulate pH of said liquid resource.
