ABSTRACT:
A process for disaggregating boronatrocalcite ore (Ulexite) in an alkaline aqueous medium for the production of sodium borate and calcium borate, characterized in that boronatrocalcite is dispersed in alkaline mother liquor having a H.sub.3 BO.sub.3 /Na.sub.2 O weight ratio ranging from 1.8 to 2.7, at a temperature of 120.degree.-200.degree. C. under autogenous pressure of 2-16 bars, under intense stirring.
