Apparatus for the blending of slurries comprises a blending vessel (7) into which the component slurries may be introduced in turn, means for weighing the quantity of each slurry introduced, means for sensing the volume of the slurry, comparator means operable in response to signals from the weighing means and the sensing means to generate a signal proportional to the specific gravity of the slurry, adjustment means operable in response to such signal to adjust the specific gravity of the slurry to correspond to a predetermined desired value, and means for delivering each adjusted slurry in turn to a mixing vessel.
