    In a zone of oxidation, siderite ores become bog iron ores. SILICATE IRON ORES. The ore minerals in silie iron ores are iron chlorites, usually accompanied by hydrous ferric oxides, and sometimes by siderite (25–40 percent iron). There is a negligible content of sulfur and up to – percent phosphorus.

  • BENEFICIATION, DEPHOSPHORIZATION AND .

    Apr 30, 2012 · Unfortunately, this large reserve cannot be utilized for the production of pig iron due to its high sulphur and phosphorus contents. In addition, the ore cannot be beneficiated easily like Itakpe and Oshokoshoko iron ores because of its texture. This work studied the beneficiation, dephosphorization and desulphurization of Agbaja iron ore.
