Investigations carried out on a wet high-intensity magnetic separator using a low-grade iron ore sample containing 49.27% Fe shows that it is possible to upgrade to 62% Fe in the concentrate with poor yield values. A “tree” procedure (generally used to evaluate the flotation performance) was followed to evaluate maximum possible yield and

Prereduction and magnetic separation of low grade

low-grade manganese ores, which contain iron oxide, may be upgraded by prereduction and magnetic separation. In this study, ferruginous low-grade manganese orewas prereduced by CO, which converted iron oxide to Fe. 3. O. 4. while manganese oxide was reduced to MnO. Then, the iron-rich component was collected by magnetic separation.
