iron ore in limestone

Iron ore often has silicon dioxide (sand) impurity which must be removed during the process. To do this limestone is added to the charge. The limestone (chemically, calcium carbonate) decomposes in the heat of the furnace to calcium oxide.

Iron ore isn't pure iron oxide - it also contains an assortment of rocky material. This wouldn't melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom.

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are …

Iron mining in the United States produced 42.5 million metric tons of iron ore in 2015, worth US$3.8 billion. Iron ore was the third-highest-value metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah.Most of the iron ore was …

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.

The iron is poured into the stacks along with coke (carbon-rich coal) and limestone (calcium carbonate). Nowadays, the iron ore normally goes through a process of sintering before entering the stack. This process forms pieces of ore that are between 10-25mm, which are then mixed with coke and limestone.
