On the other hand, integrated mills in inland areas suffer from high transportation costs of imported iron ore. These factors are likely to concentrate largescale integrated mills along waterways—rivers, lakes, or coasts—while EAF minimills spread widely across mainland China. There are several historical precedents for these shifts.

Steel mill with two arc furnaces. Steelmaking is the process of producing steel from iron ore and/or steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

Historically, India has always been a net exporter of iron ore, with exports reaching a peak of around 135 million tonnes in 2010. However, exports have fallen following a series of mining bans across the country and, in 2018, imports of 16 million tonnes almost equaled exports—so the country could easily become a net importer (Exhibit 3).
