Many of the ores in Minecraft exist in the real world, such as coal, gold, and iron. Ores are rocks that contain minerals, including metals and other useful elements.

Coal is a fossil that is used for fuel. Coal is fossilized peat that has gone through biological and geological processes. Coal is composed primarily of carbon along with some hydrogen, sulfur, oxygen, and nitrogen. Coal is the largest source of  energy for the generation of electricity worldwide. Graphite in pencils is a type of coal.

Gold is the most malleable of all metals. Gold can be beaten into transparent sheets that can be used in heat and radiation suit visors. Gold is used in jewelry, as money, and in electrical devices. Gold is highly conductive to electricity.

Iron is the most common element on Earth. Iron is the most widely used of all the metals. It is used in machines and buildings. Iron proteins are found in all living organisms.

Coal, gold, and iron are ores that are useful in Minecraft and in the real world. These ores have many more uses in the real world than in Minecraft.
