Ulexite is an important boron mineral used for the
production of boron compounds. Purpose of the study has been to investigate the
dissolution of ulexite in hydrochloric acid solutions in a batch reactor and to
present an alternative process to produce boric acid. Reaction temperature,
particle size, solid/liquid ratio, acid concentration and stirring speed have
been selected as parameters on the dissolution rate of ulexite. The parameters
used in experiments are; acid concentration 0.75*,1,1.25,1.5,2M,
reaction temperature 30*,40,50,60,70oC, particle size
-14+18*,-18+30,-30+40,-40+50,-50+60 mesh, solid/liquid ratio
5/100,7.5/100,10/100* g/mL, stirring speed 500*,650,800
rpm. It has been found that the dissolution rate has increased the reaction
temperature and the stirring speed. However, increasing the particle size, acid
concentration and solid/liquid ratio have decreased the rate of dissolution.
