How to Manufacture Pig Iron: How Pig Iron is made?
The crushing of ores helps in two ways: (i) The ore particles of uniform size are obtained. (ii) The reducing gases penetrate the ores in a better way. If ores contain clay, loam and other earthy matter, they are washed in a stream to remove such impurities. The perforated trays may be kept in water to remove pebbles and sand.
