Manganese Ferroalloys Technology ScienceDirect

Sintering, pelletizing, and briquetting are three principal technologies used for the agglomeration of ores and concentrates. Pelletizing is a more difficult process for manganese ores than for most iron ores. It requires higher temperatures (>1150° to 1250°C) to produce strong enough manganese ore pellets, which makes it a more expensiveIt is described a manganese pellet production from non-calcinated manganese ore, comprising the following phases: (a) ore size preparation through ore classification by function of particle size, smaller or equal to 1 mm particles being maintained from the ore particle fraction process so as to have a smaller or equal to 1 mm size, as well as the Process to produce manganese pellets from non-calcinated manganese ore

Ore Sinter an overview ScienceDirect Topics

An optimized process design will naturally include the sub-process to agglomerate the accumulated fine-grained ores by means of pelletizing or sintering. Pelletizing involves the forming of ore fines (pellet feed) and concentrates with grain sizes of well under 1 mm into pellets of around 10 to 15 mm in diameter by addition of a binding agent.Iron ore granulation has been introduced into the steel production process since iron ore agglomeration was proven to have better metallurgical properties and more efficient iron production than natural iron ore 6,7). Both sintering and pelletizing contain iron ore granulation process, with the former preparing iron ore, fuel, flux, water andIron ore granulation for sinter production:

Innovative Development on Agglomeration of Iron Ore

such as sintering, pelletizing, or briquetting, are required. Sintering is the oldest, easiest, and energy-efficient process to use these fines. Therefore, in most of the steel plant sintering routes are followed for using these undersize iron ore. However, sintering has a size limitation. Excessive fineness (<0.5 mm) loses its bed permeability.Later since twentieth century, sintering and pelletizing process has become the main industrial agglomeration technologies for utilisation of fine dust and ore particles.
