Magnet Picks Up Real Rock Cinder Ballast

I have cinder ballast from Arizona Rock and Scenic Express. When I pass a magnet over samples of these cinders, nearly all the material winds up on the magnet. I have been assured by one supplier that there is no problem using their cinders with DCC. Has anyone had any issues with cinders from either supplier as far as operation on a DCC layout? Arizona’s Yard Mix also demonstrates the same behavior to a magnet.
