Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in detail to understand the influence of ...

The ferromanganese (FeMn) alloy is produced through the smeltingreduction of manganese ores in submerged arc furnaces. This process generates large amounts of furnace dust that is environmentally problematic for storage. Due to its fineness and high volatile content, this furnace dust cannot be recirculated through the process, either. Conventional MnO2 production requires the prereduction ...

However, the increase in manganese content in washed residue was found to be less compared to iron and silicon. This is perhaps due to more solubility of manganese sulphate which was absorbed in the leach residue.
