Abstract
Some embodiments of the present disclosure include a method and method for recovery of solution mined minerals. The method may include creating superheated steam using a steam boiler; passing the superheated steam through a turbine/generator to generate electricity; reheating the steam exiting the turbine/generator to saturation with a steam reheater; using the saturated steam with an absorption chiller to create chilled water; and recovering minerals using the chilled water in a cooling crystallizer system. In embodiments, the method and system may be used to recover minerals, such as potash (KCl), washing soda (Na2CO3.10H2O); nahcolite (NaHCO3); and glauber salt (NaSO4.10H2O). The method may utilize the trigeneration of steam, electrical, and chilled water utilities, which may be used for a recovery process.
