Edison was not the only entrepreneur-inventor trying to
magnetically separate iron from low grade ore for there were

the richness the ore (the prevailing business strategy of
the mining industry), but from the highly efficient processing
of great amounts ore. The historian Harold
Passer's description Edison "conservative defender of
the status quo" does not fit his activities during the 1890s?
