  • Blast Furnace – Official Minecraft Wiki

    Blast furnaces are similar to furnaces, but can smelt only ore blocks and tools/armor made of iron, gold or chainmail Once an item and a fuel are placed into the blast furnace, the block state changes to lit and the item is smelted twice as fast as a regular furnace Fuel is also used at double the rate of regular furnaces, so the number of items smelted per fuel stays the sameBlast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestoneIronmaking blast furnaces consist of several zones: a crucibleshaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends fromBlast furnace | metallurgy | Britannica

  • Blast Furnace an overview | ScienceDirect Topics

    The blast furnace process is primarily used in the carbothermic reduction of oxides, such as iron, zinc, and lead Most of the iron ore bodies commercially explored consist of iron oxides Consequently, rich iron ore and/or iron oxide pellets formed from concentrate can be added directly to a blast furnace (see Iron Production)Because ore contains many expensive metals such as copper (CoPPer), Ni (Nickel), Zn (Zinc), gold (Gold), silver (Silver), etc, so it often used as raw material for metal smelting industry using Vietnam 350 blast furnace; and as it contains a lot of sulfur, so it often used to distill sulfur, iron have become the byproductIron Ore blastfurnaces
