Research Abstract

Magnetic separation was applied to the recovery of manganese and phosphorus from dephosphorization slag and chromium from EAF slag. Dephosphorization slag consists of phosphorus enriched phase and manganese enriched phase together with matrix phase. The magnetic property of each phase has found to be significantly different. In the present experiment, about 31%of phosphorus enriched slag could be recovered at untrapped 3 of 0. 30T and about 14%of manganese enriched slag could be recovered with less than 20%of phosphorus enriched phase contamination at trapped of 0. 03T, particle size of less than 32μm with physical agitation. Chromium was also recovered from EAF slag as iron-chromite with about 50%of Cr. It was thus demonstrated from the present experimental results that phosphorus, manganese and chromium can be recovered from steelmaking slag which can be recognized as their secondary resource.
