(with pictures),Iron ore is smelted to produce usable iron. Steel production consumes the vast majority of iron ore produced around the world. To make steel, firms start by crushing and pre-processing ore before smelting it to free the trapped metal with a heat and chemical reaction. This can be used to make so-called “pig iron,” solid blocks of iron that can be further processed.The Smelting Industry: Global Importance And Risks,2017. 4. 25.· 3. Methods and Processes .
