Platinum 1997

SHARE THIS PAGE:

Monday 19th May saw the launch of “Platinum 1997”, the latest annual survey, published by Johnson Matthey, of the supply, demand and applications of the platinum group metals during 1996.

Supplies of platinum fell by 2 per cent to 4.9 million oz during 1996 due to lower Russian exports and a slight decline in production from South Africa. The price of platinum in 1996 averaged $397.32, compared to $424.22 in the previous year. This was closely tied to the price of gold, reaching a peak of $433 in February and then falling throughout the year to a low of $367 in mid December, despite a temporary recovery in early August due to a series of disputes in South African mines.

Demand for platinum rose by 40,000 oz to reach a record of 4.88 million oz in 1996. The use of platinum in autocatalysts fell by 30,000 oz to 1.82 million oz due to some manufacturers switching to palladiumbased technology on gasoline cars. Stricter controls on emissions, however, resulted in an increase in platinum demand for diesel vehicles, as only platinum technology is suitable for the extremely high air:fuel ratios of diesel engines. The introduction of direct-injection gasoline engines, operating under similar lean conditions, is expected to boost the demand for platinum in the future, as may the future commercialisation of fuel cells, for both automotive and stationary applications. Industrial consumption of platinum rose by 95,000 oz to 1.12 million oz with demand rising for platinum coated hard disks installed in personal computers and for speciality glasses used in television screens and computer monitors, which are produced using platinum-based equipment. There was also strong demand from the petroleum sector for platinum catalysts used in the production of cleaner diesel and unleaded petroleum and for the dewaxing of engine lubricating oils. Sales of platinum to China reached a record 200,000 oz, most being to the jewellery sector, but investment in China’s industrial infrastructure also required significant amounts of metal.

Demand for palladium rose by 30,000 oz to 6.15 million oz. Much of this was to the auto sector; around 60 per cent of European gasoline cars sold last year were equipped with palladium-based catalysts, as were those produced by Ford in the U.S.A. There was also increased use of palladium starter catalysts needed to meet the hydrocarbon limits imposed by Low Emission Vehicle legislation in the U.S.A. This demand is forecast to rise as emissions legislation is tightened further. Demand for ruthenium and iridium was greatly increased, mainly due to the development of processes using ruthenium and iridium to produce ammonia and acetic acid, respectively.
