What is Iron Ore used for? Iron ore is part of our everyday lives and our modern world would look completely different without it. 98% of world iron ore is used to make steel, which accounts for over 90% of all metals used in the world. Steel is used in building for so many things, from cars, trains and ships through to the high rise buildings ...

Hematite, the most desirable iron ore because of its high iron content, is found throughout the world, with its highest abundance being seen in Australia, Brazil, and parts of Asia. Since the 1960's, high-grade hematite ore has served as the major source of iron mined in Australia. It comprises 96% of the iron ore exports from that continent.

On the average, destructive distillation yields approximately 32–38 percent charcoal, 45–50 percent liquid products, and 16.5–18 percent gaseous products (see Table 1). The size and moisture content of the pieces of wood being distilled have a bearing on the product yield, as do the temperature and rate of the process.

There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.

Charcoal Charcoal is the residue from the destructive distillation of wood. It absorbs moisture readily, often containing as much as 10 to 15 percent water. In addition, it usually contains about 2 to 3 percent ash and 0.5 to I.O percent hydrogen. The heating value of charcoal is about 27,912 to 30,238 kj/kg (12,000 to 13,000 Btu/lb). [Pg.2361]
