Iron Ore is a relatively common ore in Minecraft, second only to Coal Ore in terms of frequency. It occurs in veins of about 1-10. Iron ore is a stone block with tan flecks. It is near mandatory that the player gets some iron near the beginning of the game, since it is used for mining all ores except for itself, Lapis Lazuli, and Coal (the former two are mined with a Stone Pickaxe, while the latter can be mined with any pickaxe). To mine iron ore, a Stone Pickaxe or higher must be used, which yields one Iron Ore block. Gold and wood pickaxes do not work and will drop nothing. This ore is smelted in a Furnace to make one Iron Ingot, which also yields some experience.
Iron could be called the most useful tool component in the game, as it can mine all the ores and is necessary for mining diamond, gold, redstone, and emerald.
Iron and gold are the only ores that need smelting, providing a Silk Touch enchantment was not used to mine other ores.
Iron Ore is not affected by the Fortune enchantment.
Iron is a good material to make everyday armor and weapons out of, as it is relatively cheap, and easy to make.
