Iron Ore Processing Explained

Siderite beneficiation. the main component of siderite is feco₃. the theoretical grade is 48.2. because the theoretical iron grade of siderite is low, and it often coexists with calcium, magnesium, and manganese in a similar symbiosis, physical beneficiation methods are often used, and the iron concentrate grade is difficult to reach more.

China is rich in siderite resources, which are difficult to exploit by traditional beneficiation methods. the development of efficient utilization technology for siderite can increase the reserves of available iron ore, improve the tight situation of iron ore supply, and ensure the iron ore security of china.
