ABSTRACT:
Method of agglomerating solids in a liquid suspension utilizing in the bridging liquid an additive chemically active with respect to such solids. The solid to be agglomerated is suspended in a first liquid which is, or is made to be, at least relatively nonwetting with respect thereto. A second immiscible or bridging liquid is then introduced into said first liquid. Said second liquid is, or contains dissolved therein material which is, reactive to such solid material. The entire system is then agitated and the solid material thereby formed into agglomerates. The use of a chemically reactive material in the bridging liquid provides a wide range of selectability of and control over the properties, either physical or chemical, of the resulting agglomerates.
