How To Grind Tungsten On A Bench Grinder

I also like to use a 120 grit sanding disc on a 4 12 grinder along with a cordless drill motor.For most folks, a cheap bench grinder with a 100 -180 grit stone will be fine.Not optimum, but fine.But wont that contaminate the tungsten with other metals or embed particles of aluminum oxide in the tungsten.
