— Smelter slag is initially deposited in piles. These slag piles range in surface area from one to 75 acres, and in height from three to 45 meters. Slag is associated with smelter operations, which may or may not be co-located with the mines. Copper slag can be used either as sandblast grit or an additive to concrete.
