By weight, the cement lining doesn't account for much when you're talking about ductile iron. Now, it's been a while since I've taken any in, and I honestly don't remember whether I had it mixed with anything else when I did. But I know that I have scrapped it, so it's not like they won't accept it.



And again, it'd be best to check with the yard(s) you're dealing with, cause it can vary from one to the next. Not that it's ductile iron, but case in point, of the yards I go to, for rebar, one yard pays about 2/3 the price of heavy melt, and another pays the same as heavy melt, and it all goes in the same pile. Cast iron pays less at both yards, but at that second yard, they tell me to mix my cast in with shredder, cause shredder pays better.
