How to Manufacture Pig Iron: How Pig Iron is made?

The calcination consists in heating ores in presence of air so that they are oxidized. The water and carbon dioxide are removed from ores by calcination. The roasting consists of making the ores hot and very dry. It is adopted to dissipate the volatile parts, especially sulphur, by heat.
