The left-over residual brines after extracting anhydrous sodium sulphate, halite and epsomite are stored in storage ponds inside EMISAL Co. battery limit and its quantities amounts to about 120000 m3 annually. The waste of left-over brine enriched with economic valuable ions, as boron and potassium of specific gravity up to 1.300 g/cm3. The present study proved the economic possibility of extracting some valuable salts as sodium borates, boric acid and potassium chloride from the waste residual brines and its economic utilization in local markets.
