Abstract In this research, ferrotitanium was produced from titania slag by an aluminothermic process in an Electro Slag Crucible Melting (ESCM) furnace. The effect of Al and flux additions on titanium recovery, ferrotitanium yield and Ti/Al ratio were studied. It was found that an increase in Al amount led to a decrease in Ti recovery and Ti/Al ratio, …

Reduction with aluminium (thermit process or alumino-thermic process
In the thermit process, aluminium powder is mixed with metal oxide. A piece of magnesium is set alight to start the reaction. The aluminium reduces the oxide to free metal. In case of iron oxide, iron is obtained in the molten state. (The mixture of iron oxide and aluminium powder is called thermite).

Aluminothermic Process
The aluminothermic process works by taking two oxide compounds—one of which must be an aluminum oxide (Al2O3)—and combining them together in a sealed container that is heated up to an extremely high temperature (usually around 1,000°C). The heat causes the aluminum oxide to break down into oxygen and elemental aluminum.
