India’s state-owned National Aluminum Co Ltd (NALCO) has signed a Memorandum of Understanding (MoU) with another public sector company, Indian Rare Earths Ltd (IREL), to jointly set up a titanium slag plant.
That could be good news for India’s space program. Why? The project envisages adding value to Ilmenite, a titanium-iron oxide mineral, to produce the slag. Slag is an intermediate product for making titanium sponge and titanium pigments. Titanium sponge is a porous substance formed in the first stage of processing of the naturally available titanium. The latter is high strength but has low density properties, and is also corrosion-resistant. It’s widely used in the manufacture of aircraft, among other things. Titanium-alloy components are also used to make missiles and satellite launch vehicles.
Incidentally, just a few weeks ago, The Indian Space Research Organization (ISRO) launched five foreign satellites, marking an important milestone in its space program.
IREL operates under India’s Department of Atomic Energy. When complete, the plant will make 100,000 tons (1 lakh ton) of titanium slag in the eastern state of Odisha. Some of it will also be used to make pig-iron. A feasibility study and technology selection on the project will soon be carried out.
The plant is estimated to cost around $82 million (Rs 500 crore). The MoU for formation of the joint-venture had been signed between the two central public sector entities about three years ago but was revalidated last week. No explanation was given for the delay.
