I'd suggest not. These are not semiconductors. They are tiny toroid ferrite cores with two windings around each--one for reading and one for writing.

Of course you probably wouldn't get toroids when chipping from ferrite. On the other hand you wouldn't get semiconductors when chipping from silicon either.
