Layer charge on the 2:1 parent material and on the 2:1 and 1:1 alteration products ranges from the maximum of that for illite to a minimum near zero. The wide range of possible layer charge on the 2:1 layer suggests that mixed-layered kaolinite/expandables (K/E) would be a better name than kaolinite/smectite.

Bacillus subtilis was used to demonstrate microbially induced selective flocculation to separate kaolinite and hematite. In neutral pH range of 7 - 8, 90 - 95% of hematite was selectively flocculated whereas 80 - 85% of kaolinite was dispersed using hematite - grown cells. Hematite- grown cells exhibited significant adsorption onto hematite than onto …
