2019-12-12 · The flocculation and solid/liquid separation of four well-characterized kaolinites (2 well, 2 poorly crystallized) have been studied for comparison of surface structure (SEM), aggregate structure during flocculation (cryo-SEM), settling rate, and bed density (with raking). It is shown that major differences in these properties are largely due to crystallinity and …

2007-12-14 · Once the clay beds have dried completely, these internal laminae appear to layer parallel on surfaces perpendicular to bedding . Drying out, however, also leads to separation of the top portions of layers along bottom-parallel fractures and reveals that the overall deposit is characterized by low-angle, downcurrent-dipping cross-strata ( Fig. 4B ).
