Photoreduction of the leached solution with sunlight provides ferrous oxalate dihydrate and the dihydrate can be further converted into manganese ferrite by roasting at 500 °C for 4 h. On the other hand, undissolved manganese and iron in the leaching residues can be further recovered by the roasting and magnetic separationLive Chat

As a potential solid waste resource, lowgrade ferromanganese ore has not been fully utilized or recycled. In this study, fluidization magnetization rLive Chat
Then, the prepared fluid was introduced into the separation chamber under gravity, in which a magnetic field perpendicular to the direction of flow was generated using an electromagnet. The magneticLive Chat
Separation and recovery of iron and manganese from highiron manganese oxide ores by reduction roasting and magnetic separation technique Yuanbo Zhang School of Minerals ProcessingLive Chat
The reduction roasting products of lowgrade manganese ore, mainly comprising of MnO, metallic iron, and residual gangue, could be separated effectively to obtain richmanganese ore and magnetic product. The RMn, RFe, and TMn can reach the peak values of 71.00%, 93.60%, and 56.20wtLive Chat
