ABSTRACT:
Inorganic metallic compounds, particularly salts, oxides and hydroxides, are removed from solutions by removing at least a part of the solution liquid and stirring and cooling this part while in the metastable state until a crystallization of the metallic compounds is rendered possible. Then energy is fed in bursts to the cooled down part in order to initiate the crystallization. The crystallized metallic compounds are separated, leaving a residual liquor which then is transferred back to the solution.
