Copper Slag Gradation: Reverberatory copper slag can be processed into coarse or fine aggregate material for use in embankment appliions. Copper slag can readily satisfy the gradation and physical requirements of AASHTO M145. (11) Unit Weight: Copper slag has a unit weight of 2800 to 3800 kg/m 3 (175 to 237 lb/ft 3).
Since copper smelting slag contains high content of iron, and copper and zinc, common appliions of copper smelting slag can be used in valueadded products such as abrasive tools, roofing granules, roadbase construction, railroad ballast, fine aggregate in concrete, etc. Some studies have attempted to recover metal values from copper slag.
