coarse lumps. In this process, the crushed ore is agitated or shaken in water with a vertical motion. This permits the heavy lumps to settle to the bottom and the lighter rock to remain on top. For more finely crushed ore, another concentration method is used. The ore is crushed to sand-size particles.
