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.

采用磁选技术从脱磷渣中回收锰、磷，从电炉渣中回收铬。脱磷渣由富磷相、富锰相和基体相组成。已经发现每个相的磁性显著不同。在本实验条件下，当未捕集率为3/0时，富磷渣的回收率可达31%。当捕集剂捕集量为0. 05 μ g/L时，富锰渣可回收14%左右，富磷相污染小于20%。03 T，粒径小于32μm，采用物理搅拌。铬也以铁铬铁矿的形式从电炉渣中回收，其中铬含量约为50%。实验结果表明，磷、锰、铬可以从钢渣中回收，并可作为其二次资源。
