Tantalum demand grows as electronic devices shrink

P Solman
Financial Times, 23 Nov 1999, p 28

The tantalum market is undergoing significant changes, as demand grows and traditional production gives way to mining from ores. Tantalum has become increasingly important to the electronics industry where it is used to make high-quality capacitors for mobile phones, computers and similar small devices. The main advantage of tantalum is that it has a very high capacitance per volume, and for this reason, it has benefited from the trend towards making electronic objects smaller. Electronic applications now account for almost two-thirds of all tantalum consumption which is now about 4 million lb/y and growing at a rate of 4 to 5%/y. A side-effect of that growth is that one of the traditional methods of production - the recovery from slag created by producing tin - is beginning to be exhausted. The main source of tantalum has shifted to mining from hard ores, and this now accounts for 40% of supplies. Australian mining group Sons of Gwalia has the world's largest tantalum reserves at its Greenbush and Wogina mines in Western Australia, which produce half the world's mined tantalum. Much of the metal is sold through long-term confidential contracts.
