摘要：
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°C and at a pressure of 2-16 bars, under intense stirring.
