Abstract
A method for selective solution mining mineral recovery may include heating a wellfield injection brine to a temperature from about 100° C. to about 250° C.; injecting the heated wellfield injection brine into an underground wellfield to dissolve soluble minerals therein, creating a hot brine solution; removing the hot brine solution from the underground wellfield; and recovering the soluble minerals from the hot brine solution by cooling the hot brine solution to a temperature of from about −10° C. to about 5° C. and causing the soluble minerals to precipitate recovered minerals in a solid form.
