Ores are usually extracted by being mined. They can sometimes be found on the Earth's surface. The metal in ore is often valuable. There are different ways to get the metal out of the ore. Iron ore, for example, is smelted in a blast furnace.
Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.

Iron was likely originally discovered and extracted as a result of wood burning on top of ironcontaining ores. The carbon within the wood would have reacted with the oxygen in the ore leaving a soft malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia presentday Iraq between 2700 and 3000 BC.
