Abstract
The energy consumption in the ferroalloys industry has become an enormous challenge as the
cost is increasing while the quality of the raw materials is not changing to compensate the
lowering of the quality. It has become important to look at the use of valorising low quality
raw materials and its implication on the energy consumption as well as the quality of the metal.
The current study investigate and contributes to the valorisation of the low quality manganese
raw materials namely carbonates manganese ores.
