tonnes/y. (See also 'Focus on Pigments', Dec 2005, 4). KMML's pigment plant uses chloride-route technology, licensed from Tronox (formerly Kerr McGee) since the mid-1980s. Hence, KMML has substantial experience in producing and handling titanium tetrachloride, a key intermediate in TiO 2 manufacture. Employing technology developed by the Defence Metallurgical Research Laboratory, KMML is building a 500 tonnes/y titanium sponge metal plant, at its Sankaramangalam site. The plant should be ready for operation by the end of 2007. At full capacity, the sponge metal plant would require about 2000 tonnes/y of titanium tetrachloride, to be supplied from KMML's existing facilities. Funding for this venture -around Rup 1 billionis being provided by ISRO. This figure includes Rup 45 M, allocated to training of KMML plant operatives by engineers from the Defence Metallurgical Research Laboratory.
If operations at the 500 tonnes/y stage prove successful, KMML is planning to double capacity to 1000 tonnes/y at an additional cost Rup 950 M.
Meanwhile, KMML has also been negotiating with potential sponge metal licensing partners from Russia, Ukraine, the UK and the US. The ultimate objective of these negotiations was the establishment a 10,000 tonnes/y sponge metal plant in southern India. However, declaration of a decision to go ahead with the much smaller facility employing technology developed in India may mean the abandonment of the 10,000 tonnes/y project.
