Process for the solution mining of minerals from a subterranean formation in which a dilute carbonic acid leaching solution is injected through a first well into the formation and a pregnant liquor containing the dissolved minerals is recovered from a second well. Subsequently the direction of flow through the formation is reversed by injecting the leaching solution through the second well and recovering the pregnant liquor from the first well. Optionally, an oxidizing agent is injected either simultaneously with the leaching solution, or alternately with slugs of the leaching solution.
