process of separating the iron ore from other rock
Separating Iron and gold from rock. by Elsa Huber
There are many ways to extract iron ore from rock. Iron is magnetic so you could use a method that involves magnets, and it is also heavier than a lot of substances, so you could use a shaker and see which pieces weigh more. However, the way

The pure iron then melts and goes to the bottom of the furnace. The iron ore itself is not pure ore. It is also contaminated with a variety of rock, which will not necessarily melt at blast furnace temperatures and therefore could clog it up. For this reason, limestone, or calcium carbonate, is added to the initial furnace charge.
