Using the methods of physical and mathematical modeling, the dependencies of the intake of the amount of manganese ore unloaded in a mixture with iron ore raw materials from the BLT hopper to the top, on its location in the hopper and the number of the ordinal station of the tray in the matrix line for the conditions of single- and double-skip loading modes have been obtained. When manganese ore was placed in a mixture with other additional materials over iron ore in the hopper, the BLT ensured its flow in the time interval falling on the second and third annular zones of the top. The content of manganese ore changed during discharging from 33 to 15 %. The location of flushing materials in the layer of iron ore materials after the sinter before and after the pellets ensured its maximum amount in portions formed after 30–50 % of the time of the total production duration. The flow of flushing material into the first annular zone in the direction of movement of the tray amounted to 12–18 % of the mass of manganese ore loaded into the bunker, 20–21 % into the second zone, and 14–15 % into the third zone. When the manganese ore is located in the lower part of the hopper in the conditions of a single-skip loading mode, its entire loaded volume enters the top space of the furnace from the first station of the angular position of the tray in the course of its movement.
