For example, building a single 100-MW wind farm— never mind thousands of them—requires some 30,000 tons of iron ore and 50,000 tons of concrete, as well as 900 tons of nonrecyclable plastics for the huge blades. With solar hardware, the tonnage in cement, steel, and glass is 150% greater than for wind, for the same energy output.

The main chemical reaction producing the molten iron is: Fe 2 O 3 + 3CO → 2Fe + 3CO 2. This reaction might be divided into multiple steps, with the first being that preheated air blown into the furnace reacts with the carbon in the form of coke to produce carbon monoxide and heat: . 2 C (s) + O 2(g) → 2 CO (g). The hot carbon monoxide is the reducing agent for the iron ore and …

With few exceptions, Japan's mineral reserves are small, and the quality of those mined is often poor. Coal, iron ore, zinc, lead, copper, sulfur, gold, and silver are among the most abundant minerals (in relative terms), with lesser quantities of tungsten, chromite, and manganese. Japan also has large deposits of limestone. There is an almost complete lack of nickel, cobalt, …

This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore. As such, certain steel smelters in China have developed a process for blending nickel limonite ore with conventional iron ore to produce stainless steel feed products.
