The plants for the production of pig iron or steel are called ironworks An ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing).
