Iron and steel industry in the United States
In 2022, the United States was the world’s third-largest producer of raw steel (after China and India), and the sixth-largest producer of pig iron. The industry produced 29 million metric tons of pig iron and 88 million tons of steel. Most iron and steel in the United States is now made from iron and steel scrap, rather than iron ore. The United States is also a major importer of iron and steel, as well as iron and steel products. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together.

From Ore to Iron with Smelting and Direct Iron Reduction
The Hismelt process employs a single smelt reduction vessel (SRV) where iron oxide fines are injected deep into hot metal The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction. Magnetizing roasting uses temperatures between 700 and 900 °C (1,292 and 1,652 °F) for a time of Iron ore

A review on CO2 mitigation in the Iron and Steel industry
Initially, the iron ore is pretreated in a pellet or sinter plant where limestone and dolomite are added to the mixture that is known as the burden. The burden, which In modern copper smelting, a reverberatory furnace is used. Concentrated ore and a flux, commonly limestone, are charged into the top, and molten matte—a compound of copper, iron, and sulfur—and slag are drawn out Smelting Definition & Facts Britannica

Coke (fuel)
Raw coke. Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" Figure 3 shows a comparison of the IEA and WSD views and the related iron ore demand of between 400 and 600 mt by 2050, compared to about 160 mt in 2019.

Smelting Minecraft Wiki
Smelting is a method of obtaining refined goods from raw materials by heating in a furnace, blast furnace, smoker or campfire. For example, raw iron can be smelted to produce iron ingots using coal as fuel. Like crafting, smelting uses recipes to determine what item is produced, but its recipes are simpler. Smelting also yields experience. The furnace, Iron ores are rocks and (Fe 3 O 4) to be used for iron smelting. (DRI) plants and one iron nugget plant that were operating in 2014.
