Re: reuse for garnet sludge

Technicut [http://forsee.com/hti/abjets.htm] sells abrasive waterjets using garnet for cutting metals.  Their website states that you can talk to their technical representatives at 1-800-982-8045.  I would give them a try.

I would like to ask the list if there are any suggestions for facilities
which cut metals using high pressure water.  A finely powdered stream of
garnet is added to the water as an abrasive and quickly settles to the
bottom of the tank.  This "sludge" is currently being pumped out and
disposed of.  Large pieces of metal are removed, but the sludge surely
includes a substantial amount of metals and other cutting materials.

Any ideas for the beneficial reuse of this product?
