You have to find a way to somehow separate the different metals whether that be bashing them out or using cutting tools to achieve that end. If it's too difficult you have you accept the much lower rate for irony aluminium.
With the flywheels that have magnets pressed into them, I have successfully used a hammer to knock them out after partially loosening them with a screwdriver. Otherwise I break them into chunks and submit the pieces with the magnets as irony aluminium and the rest as pure cast aluminium.
You must consider the sheer extra weight of the other metals with irony goes a small way to gaining a little lost ground. It's still worth more then ferrous metals.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
