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. The trucks take the taconite directly to the processing plant, or the taconite is transported if further away. Crushing
