value of zinc process, page-39

Hi Seik

Thinking about it a bit more, and hopefully adding a bit more...

I'm with you with the fluid bed. It's their main strength. We know they are also into:

roasting and magnetic separation, (ERMS) and

leaching, filtering, washing, calcinating. (EARS).

Additionally, as an aside, my understanding is that agglomeration takes place in a fluid bed, (where else!!) and they are not using any binders (and presumably that includes flocculants).

OK. So we've got a strongly acidic and therefore probably enclosed environment, some filters (carbon?), and some heat (for the calcination). And a presumption of no binders or flocculants.

Possible variables - pH, heat, wash solution?, pressure and rate of flow of the liquor. May be a reagent to help change state (valence) ???


Very intriguing - could that be the actual patent application? I can't seem to navigate anywhere from that page, but I've been having linking probs.....
