Here are three actions they should consider taking. Accelerate high-grade production. Iron ore mining companies already prioritize the production of better-quality ores, but they need to do more. Ores with more iron content and fewer impurities enable manufacturers to produce higher-value-added green steel efficiently.

Smelting reduction (SR) processes are the latest development in pig iron production. The SR process emerged during the 1990s. In SR processes, iron ore and coal are added directly to a metal-slag phase where the ore is reduced. The SR process combines the gasification of coal with the smelting reduction of iron ore.

Iron ore is one of the basic among other raw materials used in the production of iron. It is described as any mineral substance that contains enough iron which makes its smelting a viable proposition, i.e. an iron content of less than 20%.

Smelting is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, charcoal, and coal.
