Case No. OSMC-11, ABSTRACT OF THE DISCLOSURE Disclosed is a method for separating, initially non-magnetized ferromagnetic material. The material has a distribution of magnetic parameters and is separated into a first fraction having relatively high magnetic parameters and a second fraction having relatively low magnetic parameters. The method comprises applying a magnetic field to the materials, the magnetic field being high enough to magnetize the low magnetic parameter fraction but low, enough to avoid substantial magnetization of the high parameter fraction. Thereafter the fractions of material are magnetically separated.

Why it's free to use
- Granted June 1, 1993. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended June 1, 2010.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
