  Process for the preparation of alkali borates.



   The subject of the parent patent no. 91895 is a process for the production of alkali pentaborates by treating alkali-containing boron ores or such. which have been mixed with alkali with carbonic acid under pressure, the alkali content being adjusted in this way. that pfntaborate is obtained as the end product.
 EMI1.1
 Alkaline earth metal, to be treated with alkali and alkaline earth bisulfite to obtain pentaboric acid. But it was not to be expected that with sulphurous acid and such ores that one

 in such a way that, in the process of the parent patent, the carbonic acid is replaced by sulphurous acid while deliberately adjusting the potassium content.
