Abstract:

Nahcolite solution mining process comprising drilling at least one well into a Nahcolite bed, circulating hot barren aqueous liquor in a cavity in said Nahcolite bed for a time sufficient to produce a pregnant liquor having an increase in the concentration of NaHCO. sub. 3 in the range of from about 3 to about 20% while maintaining Na. sub. 2 CO. sub. 3 concentration in the range of about 0. 25-4%, preferably less than 2. 5%, withdrawing said pregnant liquor, cooling said pregnant liquor to preferentially precipitate NaHCO. sub. 3 therefrom and to produce a barren liquor, recovering said NaHCO. sub. 3, and reheating and re-injecting said barren liquor in said well.
