    Siderite Ore Calcination of Guangzhou siderite ore became very active from about 1000 s to 1475 s, within which period the mass of the pellet dropped from 47.5 mg to 37.5 mg. The temperature range corresponding to this weight loss was 380 C to 540 C. The composition (by XRF) of the calcined ore is shown in Table 2. The Fe 2 O 3

    Jan 08, 2016 Jan 08, 2016 An alternative technique for the beneficiation of these ores is the calcination. Calcination is the process of heating the ore to a high temperature ranging from 800 to 1000 C to decompose CaCO 3 and MgCO 3 to CaO, MgO and gaseous CO 2. The CaO and MgO formed are then removed as hydroxides by quenching the calcined product in water and washing
