ABSTRACT:
The process comprises first forming a non-homogeneous aqueous mixture of the low solubility particulate material in a closed aqueous solution formation area by combining the low solubility particulate material and water. Next, low shear forces are imparted to the non-homogeneous aqueous mixture of the low solubility particulate material. The aqueous solution of the low solubility particulate material and substantially all of the particulate material dust associated therewith are removed from within the closed aqueous solution formation area by exerting a partial vacuum on the aqueous solution of the low solubility particulate material from outside the formation area. The process can also include the step of imparting the high shear forces to the non-homogeneous aqueous mixture of the low solubility particulate material which both particularizes and conveys at constant volume the low solubility particulate material. In the process of this invention, the aqueous solution of the low solubility particulate material typically contains substantially no undissolved visible particles of the low solubility particulate material.
