Typical harmful minerals in iron ore include pyrite, apatite, etc., which contain the harmful elements S and P. They are also weakly magnetic. However, if their magnetic susceptibilities are smaller than those of the iron minerals in oxidized iron ores, it is still possible to partially remove them from oxidized iron ores by magnetic separation.
