Abstract
The invention is a method for flocculating clay including the steps of preparing a dispersion of a processed clay containing a polymer as a flocculating agent. The polymer is present in an amount sufficient to cause bridging of particles of the clay in the dispersion by the polymer. Then the dispersion is mixed to cause the polymer to bridge the particles and the particles flocculate. The invention also includes a structured clay produced by this method.
