Remnant sodium hydroxide (NaOH) and sodium carbonate ([Na.sub.2]C[O.sub.3]) from the Bayer process plus the formation of desilication
products (DSP), sodalite and cancrinite, result in Na being the dominant ion in unamended residue.

Direct flotation shows us the useful and effective techniques for Desilication
from diaspore bauxite ; Feng et al., 2001 Lu et al., 2002).
 observed desilication
and partial decomposition of highly dealuminated zeolite Y framework resulting in Al enrichment.
Clay sample from this cold region is subjected to little desilication
, hence silicon concentrations is therefore stable as silicates minerals.

Furthermore, the mineralogical composition (~58% quartz, 22% hematite, 7% gibbsite, 5% goethite, 1% anatase, 1% desilication
product (DSP), 1% muscovite, and 0.3% boehmite; Taylor and Pearson 2001), and the presence of amorphous Fe and Al oxides (0.7%) ,suggest BRS contains colloids that can limit plant nutrient availability due to specific adsorption mechanisms (e.g.

The two pressure filters, meanwhile, were a new Latham Engineering 470 [mm.sup.2] deammoniation scrubber filter and a reconditioned Lathan 2,000 x 1,500 mm desilication

of species 34 48 47 53 42 66 A second possible explanation for the peak in total P at the Kohala site is that desilication
rates may exceed losses of P throughout early soil development, resulting in P enrichment of the soil profile at mid-soil development.
