Recycling Metal Dust

Okay scrappers, I have a question concerning recycling metal dust. This product is created in many machine shops around the world. It is basically a combination of metal dust, stone dust and a very small amount of coolant. Metal Dust is created when using a large grinder to plane or grind small amount of metal/steel from a part or product. I have been given 42 - 55 gallon steel drums full of Metal dust, each drum weighs about 1800lbs.



My question is. Do any of you know of a scrap yard that will buy it? Or of any seller in general? I have used about 10 drums of it on my driveway to fill in low spots ( pot holes) however, I have A LOT of it left over.

My local scrap yard won't buy it, because they say the foundries do not want it, as the available metal/steel basically disappears once they begin the melt down process.

Any Ideas? or Any Suggestions??


EDIT: This is not Ni Temp Nickel , It is just cold rolled steel, for the most part.
