PELLET MANUFACTURING CHARGE Russian patent published in 2012 - IPC C22B1/243 

FIELD: metallurgy.

SUBSTANCE: pellet manufacturing charge includes manganese raw material in the form of manganese concentrate, slag formation flux, reducing agent and binding agent. As binding agent, it contains slag as a result of melting of metal manganese, which is pre-crushed till specific surface area of 450-500 m²/kg in quantity of 7-14%. Water is added to the above charge, pellets are made and subject to hydration, and hardening and drying is performed at room temperature.

EFFECT: increasing mechanical strength of pellets, reducing the amount of moisture in pellets, decreasing the sintering temperature and reducing the consumption of carbonaceous materials.
