Study on Magnetizing Roasting Tests of Wangjiatan Siderite under Fluidization

Abstract

Abstract: The effect of temperature and atmosphere conditions on the magnetization of Wangjiatan siderite under fluidization was investigated.The results showed that Fe concentrate grading of 58.00% at a 90.00% recovery was achieved under conditions of the thermal decomposition ratio over 94.5% and the magnetizing conversion ratio above 89.94% at the temperature of 800~1 060 ℃ and the reducing atmosphere of 1.5%CO.Whenever in the reducing atmosphere（0~1.05%CO) or oxidation atmosphere（0.47~1.85%CO),Fe recovery can reach achieved 90.00% at the temperature of 1000℃.

Key words: Siderite, Fluidization, Magnetizing roasting
