LECTURE NOTES
As there is a partial separation of gauge from the ore, lesser amount of upgraded ore is to be smelted for a particular output capacity. This reduces the fuel and energy consumption per ton of metal smelted. 6. Reduction of the total smelting cost: As there is a partial separation of gauge from the ore, lesser amount of
