Polishing material

I'm refining precious metal from jewelry polishing dusts. After separating precious metal out, I will get lots of polishing material remain. My question is what business can make use of this material. The composition of this powder is SiO2 80-85%, Al2O3 10-15%, Iron Oxide ~2-5%.

I applaud that you want to recycle this, but I would be surprised to hear that a used, mixed, abrasive is of any value at all.

Could anyone in this recycle polishing dust tell me what would you do with used abrasive coming from polishing dust? Since we have lots of this used material, any use for other application or just dump it?
