siderite in hematite iron ores

  • Synthesis of magnetite powder from the mixture

    Lowgrade iron ores containing siderite or hematite cannot be easily beneficiated due to their lowmagnetic properties In order to solve this problem, magnetizing roastingmagnetic separation technique can be used This method of beneficiation is based on thermally induced transformation of weakly magnetic iron minerals into magnetiteThe siderite–hematite mixed iron ore used in this study was collected from Guizhou Province, China The chemical composition, as measured by Xray fluorescence (XRF), is presented in Table 1 The iron grade was 402%, which is higher than the average grade of iron ores in China (32% Fe) Iron, as the main element within the sample, presentedMechanism of improved magnetizing roasting of sideriteUnder these conditions, siderite and hematite completely transformed to magnetite, since solely magnetite was detected in transformed samples Simultaneous roasting of hematite and siderite ores is a simple and an economically efficient technique for magnetic powder preparationSynthesis of magnetite powder from the mixture
