Answer 2

Limestone

Explanation:

• Limestone is found in combination with rocks composed or magnesium and calcium carbonates and calcium carbonates. It is located in sedimentary rocks of many geological formations. Limestone is the primary raw material for the cement industry and important for smelting iron ore in the blast furnace.
• The blast furnace is a enormous steel stack that is lined with re-fractory brick, where the limestone and other raw materials are put onto the top, and pre-heated air is then blown into the furnace's bottom. The raw materials need 6-8 hrs to get down to the end of the furnace where it becomes the final product
