Process for producing a suspension by precipitation of a solid from a solution, wherein at least two solutions of salts are combined with one another in a stirred vessel so as to form a sparingly soluble solid, where
portions of suspension are taken off continuously or discontinuously,the portions taken off in this way are processed in a combination of two separation apparatuses, wheregas is separated off in a first separation apparatus which is selected from liquid-gaseous separation apparatuses,and mother liquor is separated off from precipitated sparingly soluble solid in a second separation apparatus selected from solid-liquid separation apparatuses, and the mother liquor is taken off,and the solid which has been separated off or enriched in this way is returned to the reaction mixture. |
