RE: Waste Iron Powder



1) try buying pre-screened product from the supplier.  If the increased cost
were nominal, it might pay for the trouble of screening it and disposing or
recycling it.

2) try selling back to supplier for blending into their product.

3) try finding another supplier that will work with them if their current
one will not.
