Separation of hematite from banded hematite jasper (BHJ) by magnetic coatingSubhashree Singh, H. Sahoo, S. S. Rath, B. B. Palei, B. Das(CSIR-Institute of Minerals and Materials Technology, Bhubaneswar-751013, India)Abstract:The separation of iron oxide from banded hematite jasper (BHJ) assaying 47.8% Fe, 25.6% SiO2 and 2.30%Al2O3 using selective magnetic coating was studied. Characterization......
Phase transformation in suspension roasting of oolitic hematite oreLI Yan-jun(李艳军)1, WANG Ru(王儒)1, HAN Yue-xin(韩跃新)1, WEI Xin-chao(魏新超)2(1. School of Resources and Civil Engineering, Northeastern... is a promising method to upgrade oolitic hematite ore. An oolitic hematite ore was roasted using suspension roasting technology at different temperatures. The phase transformation for iron minerals......
