Manganese.
Small manganese ore particles are sintered before smelting primarily to agglomerate them into larger, more manageable forms.1
In the context of metallurgical processing, sintering involves heating small particles to temperatures below their melting point to weld them together. By converting fine, undersized ore particles into larger, solid lumps, the material becomes better suited for use in a blast furnace or electric furnace. This process is essential because fine particles can impede the efficient flow of gases and materials within the furnace, whereas larger, sintered lumps improve the physical properties of the feed, ensuring a more stable and effective smelting operation.23
