CHAPTER-5 GEOCHEMISTRY OF IRON ORES

2012-8-16 · Iron formation facies are of oxide type, silicate type, carbonate type and sulphide type depending upon the thermodynamics (Fig.-1) of the depositional environment. The mineralogical association in these facies is given in the Table-1&2. It is to note that the dominant mineralogy of iron bearing phase differs (Hematite, magnetite, siderite, pyrite)

Synthesis of magnetite powder from the mixture

2018-6-15 · Low-grade iron ores containing siderite or hematite cannot be easily beneficiated due to their low-magnetic properties. In order to solve this problem, magnetizing roasting-magnetic separation technique can be used. This method of beneficiation is based on thermally induced transformation of weakly magnetic iron minerals into magnetite.
