بيت /what are some important ores of iron
The age of iron: from 1500 BC: The next great development in metallurgy involves a metal which is the most abundant in the earth's surface but which is much more difficult to work than copper or tin. It is iron, with a melting point too high for primitive furnaces to extract it in pure form from its ore.
