Accordingly, the environment shear (i.e., stirring rate) could modulate the degree of re-flocculation or preserve the deflocculated state of suspensions, thus changing the rate of dissolution ...
Surface chemistry In colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float to the top of the liquid (creaming), settle to the bottom of the liquid (sedimentation), or be readily filtered from the liquid.
