2021-4-6 The intent of this roasting was to use the carbon monoxide released from the thermal decomposition of siderite to reduce the limonitic iron oxides. This technique was not successful, as the amount of magnetic iron oxide produced was barely sufficient to account for the iron originally contained in the siderite.

2021-3-26 Nowadays, the process of magnetization roasting followed by low-intensity magnetic separation is one of the most effective ways to realize the beneficiation of siderite ore [8,9,10,11]. Yu et al. [ 12 ], Zhao et al. [ 5 ], and Chun et al. [ 13 ] evaluated the effects of magnetization roasting and magnetic separation conditions on iron grade and iron recovery.

2019-1-1 However, extensive research has reported that siderite is a refractory iron ore, which is difficult to utilize in the traditional beneficiation process. Its iron grade is merely 48.02 wt% in theory. Some other elements such as manganese and magnesium are closely associated with siderite and exist mainly in the form of isomorphs in siderite.

2019-3-6 Efficient use of abundant low-grade siderite ores can potentially mitigate the shortage of iron ore in the iron and steel industry in China. In this work, the beneficiation of siderite fines containing high levels of carbonates was studied using a combined fluidized-bed magnetizing roasting process. The siderite was almost completely converted into magnetite under the optimum conditions of ...
