ABSTRACT Various aluminum-smelting by-products from three production sources were received
and characterized. The waste materials were tested for compound identification and
environmental acceptance. A coarse metallic aluminum recovery test using an Eddy
Current separator (ECS) was performed using two different Circuit configurations. White
dross performed equally well with either Circuit, while black dross processing shows
significant difference on the separation results. It was found that ECS technology was
effective for particle sizes down to 6-10 mesh.
