Which of the following statements about global steel production is INCORRECT?

Explanation

Option D is the incorrect statement. The United States Environmental Protection Agency's iron and steel sector profile separates integrated steel mills from mini-mills: integrated mills use coal through cokemaking, ironmaking in a blast furnace and basic oxygen furnace steelmaking, while mini-mills produce steel from metal scrap using electric arc furnace technology without coking or ironmaking. An EAF mainly uses scrap steel and melts or refines it by passing electric current through the scrap. That is why an EAF-based mini steel plant is not tied to coal mines in the way an integrated steel complex is tied to coking coal. The other statements match standard industrial-geography logic: China dominates crude steel output, the Ruhr grew on coal, and blast-furnace steelmaking depends on iron ore and coking coal.

Why the other options are wrong

• (A) China being the largest crude-steel producer with more than half of global output is a correct statement, so it cannot be the incorrect option.
• (B) The Ruhr Valley statement is correct because its historical steel industry was built around abundant local coal deposits that supported heavy industry.
• (C) This is correct for the blast-furnace route, where iron ore and coking coal are primary inputs and therefore shape industrial location.

Concept

This tests industrial location in World Geography, especially how raw materials, energy and technology change the siting of heavy industry. RAS repeatedly asks such questions because they link resources, manufacturing regions and changing production methods.
