In the blast furnace process, iron ore, coke (processed coal), and limestone (the charge) are poured into a vessel lined with refractory (heat-resistant brick). When heated, the coke reacts with oxygen and the limestone combines with impurities and removes them from the ore. What remains is liquid iron, which is then used to form a workable metal.

Limestone was usually chosen as a cheap additive for roasting of lepidolite. 43., 54., 55., 56. In a process patented by Mazza et al., 43 a mixture of lepidolite, limestone, and water was fed to roasting at 900 °C for 2 h. The calcine was thereafter immediately quenched to release lithium, resulting in a lithium extraction of ∼80%.

Limestone has been a valuable resource since Missouri became a state. In early open pit operations, limestone was mined and crushed by hand and removed from the quarries by mules, carts and tramways. Limestone is now mined using surface and underground methods. Surface quarrying is the most common method of producing limestone in Missouri.
