Iron Mining Process - Minnesota Iron

Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces. Transportation The taconite pieces are scooped up by electric shovels. Each shovel can hold up to 85 tons of rock. The shovels place the taconite into giant dump trucks. These trucks are as big as a house and hold up to 240 tons of taconite.
