Abstract
Aspects of the invention include methods of contacting carbon dioxide with an aqueous mixture. In practicing methods according to certain embodiments, a subterranean brine may be contacted with carbon dioxide to produce a reaction product, which may or may not be further processed as desired. Also provided are methods in which a brine or minerals are contacted with an aqueous composition. Aspects of the invention further include compositions produced by methods of the invention as well as systems for practicing methods of the invention.
