calcination and iron ore mining process

siderite occurred from 450C to around 550C during the calcination in air atmosphere; moreover, the siderite could be converted into nano structured Fe2O3 The specific surface area of the material increased, and Mn2+was transformed into Mn4+, which were beneficial to the SCR.
