Extraction of Iron Concentration of Ore - An Overview

23/09/2019  A blast furnace is used for smelting to produce industrial metals where the concentrated iron ore, coke, and limestone are fed from the top, and a blast of hot air is blown into the bottom. All these ingredients are crushed into small pieces and mixed and then put on a device called hopper which controls the input.
