Manganese Ore Sintering
Strengthening pelletization of manganese ore fines …
However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature elevation system were investigated to improve the strength of fired manganese ore pellets.

How is Manganese Processed: An In-Depth Exploration
The most well-known industrial method for clotting of manganese-containing raw materials is sintering. If manganese carbonate ore is used, it is first roasted. In some cases, the ore is further subjected to sulfuric acid leaching. Then, manganese in the resulting concentrate is reduced by utilizing coke (carbothermic reduction).
