HOW DOES MINING EQUIPMENT WORK IN IRON ORE

EXTRACTING IRON OXIDES Far along the equipment chain, a relatively soft brown ore is being drilled and blasted from the mine face. Hematite and limonite, magnetite and goethite, the mining operation is extracting the rock and crushing it until the rocky deposits are evenly sized. Remember, the deposits are somewhat soft, even crumbly, but there's raw iron trapped inside the ore. Given time

Iron Mining Process Minnesota Iron

Each shovel can hold up to 85 tons of rock

Iron ore Wikipedia

Mining of banded iron formations involves coarse crushing and screening, Mining iron ore is a high-volume, low-margin business, as the value of iron is significantly lower than base metals. It is highly capital intensive, and requires significant investment in infrastructure such as rail in order to transport the ore from the mine to a freight ship. For these reasons, iron ore production
