<p>A process useful to disaggregate boronatrocalcite ore (Ulexite) in an alkaline medium for the production of sodium borate and calcium borate, characterized in that boronatrocalcite is dispersed in mother liquors preferably maintained at a pH from 11 to 12 with a preferred H3BO3/Na2O ratio ranging from 2 to 2.5, at a temperature of 120-200 DEG C and at a pressure of 2-16 bars, under intense stirring. <IMAGE></p> |
