Separation of the reground material was carried out with a matrix of coarse stainless steel wool and a 1.0-tesla applied field. Two stages of separation produced a finisher concentrate containing 63.5 percent Fe and 5.5 percent SiO2 with an accompanying iron recovery of 73 percent. The laboratory results have not been duplicated in the pilot plant.


ABSTRACT Oily mill scale recovered from steel manufacturing operations downstream of a refining stage for molten steel is recycled to the refining stage. Coarse particles of mill scale are removed in a pre-screening operation, the mill scale is mixed and blended with a binder, and the mixture is agglomerated into shapes, such as briquettes, using exter-nal mechanical pressure.
