University of Mining and Geology “St. Ivan Rilski”,. Department of Mineral Processing and Recycling, 1700 Sofia, Bulgaria. (Received 17 February 2012; Accepted 27 June 2012).Siderite - WikipediaSpathic iron ores are rich in manganese and have negligible phosphorus. This led to their one major benefit, connected with the Bessemer steel-making process. Although the first demonstrations by Bessemer in 1856 had been successful, later attempts to reproduce this were infamously failures.

siderite ore processing,Beneficiation of Deveci Siderite Ores by Calcination and Reduction .Full-text (PDF) | The beneficiation of Deveci siderite ore by calcination and reduction processes was investigated in this study. Magnetic separation was applied to calcined and reduced ores respectively to increase the iron content of the concentrates. The experimental study involved the determin.Different Types of Iron Ore - 911 MetallurgistSiderite or spathic iron ore, is usually gray or white; but at the surface it weathers to limonite, and the weathering may extend to a considerable depth. A rusty capping may cover a deposit of siderite. Where the ore forms the face of a cliff, the limonite may wash away as fast as it forms, leaving the siderite.
