  • A Better Way to Grind Ore? A Conversation with David Szego on the .

    Nov 30, 2017 . There's a huge advantage to this when you try to separate the magnetite from the gold with typical sifting equipment, the magnetite falls through the mesh because it is smaller than the holes, but the now larger and flatter gold flakes get trapped in the filters. You're not only extracting more gold quicker and.
