Limonite Siderite Iron Ore Beneficiation

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.

Selective flotation of siderite and quartz from a

2018-6-15  For the carbonate-containing refractory iron ores, Yin et al. (2010) have come up with a two-step flotation process, which is first to separate siderite from the ore to eliminate its negative effect on flotation and followed by a reverse flotation of gangue minerals typically quartz. This process has been successfully adopted in practice since 2010, giving good production indices. This innovation has effectively reduced the negative effect of siderite imposed on the beneficiation, as well as recovered the siderite resources which have otherwise been considered unexploitable. There has been estimation indicating that around 40% of the potential iron resources in the world are siderite
