smelting

Physics

The process of separating a metal from its ore by heating the ore to a high temperature in a suitable furnace in the presence of a reducing agent, such as carbon, and a fluxing agent, such as limestone. Iron ore is smelted in this way so that the metal melts and, being denser than the molten slag, sinks below the slag, enabling it to be removed from the furnace separately.

Chemistry

Iron ore is smelted in this way so that the metal melts and, being denser than the molten slag, sinks below the slag, enabling it to be removed from the furnace separately.

Chemical Engineering

A high-temperature metallurgical process in which metal is separated by fusion from impurities in minerals and ores. The metals may be chemically or physically combined or mixed in the minerals or ores. The smelting process takes place in a furnace in which the ore is mixed with a reducing agent such as carbon and a fluxing agent such as limestone. The molten metal, being of a higher density than the slag, falls to the bottom of the furnace where it is removed.
