A process for recovery of salts from a rinse liquid solution used to rinse salt flux from a metallurgical joining operation is disclosed in which process soluble flux salts are dissolved in the rinse liquid solution while other insoluble salts are dispersed therein. The process comprises collecting the rinse liquid solution; removing undissolved solids from the solution; concentrating the remaining solution by removal of liquid to provide a slurry; subjecting the slurry to a drying operation to remove the balance of the liquid; and recovering the residue. In a preferred embodiment, the residue is analyzed and sufficient metal salts are added to restore the residue to a desired salt flux composition for reuse.
