Importance of Microscopic Studies in Mineral Dressing

ore and gangue is too intimate to effect any separa-tion at the size ranges employed in ore dressing, and thus will avoid considerable amount of, futile testing. Studies of mill products are often helpful to determine whether the loss in grade or recovery, if ever it happens, is due to intergrowth of the mine-rals or inefficient operation.
