' From crude platinum placers and byproduct platinum-group metals recovered largely from domestic copper ores. 1043Platinum-Group Metals By J. M. West 1 On the strength of a sharp upturn in consumption and growing anticipation that relatively large quantities of platinumgroup metals might be needed within a few years for automotive exhaust control, platinum prices and world production posted significant increases in 1972. By the second quarter, U.S. dealers' prices for platinum and palladium had exceeded producers' prices. By early May, the dealers' price for iridium had rocketed from $145—$148 to $525 per ounce, settling back thereafter. During the year, U.S. mine and secondary production declined 5% and 8%, respectively. However, refinery output of new metal, mainly from imported concentrates and matte, nearly doubled. The volume of metal refined on toll declined, mainly because of a drop in palladium recycling. Imports rose about 534,000 ounces; exports rose 134,000 ounces; stocks, including those on the Mercantile Exchange, rose 69,800 ounces; and sales rose 294,100 ounces. Overall sales were up 23% over those in 1971, with gains in sales of each platinum-group metal. The most significant increase was in sales of platinum, which rose 26%; iridium and ruthenium sales ex panded greatly as a result of new chemical and petroleum uses. Work! production of platinum metals rose 1~% in 1972, owing to mine and refinery expansions in the Republic of South Africa and the U.S.S.R. Canadian production declined because of production cutbacks in the nickel industry, thereby limiting byproduct platinum output. The bulk of the South African production continued to be platinum, while the bulk of the U.S.S.R. production was palladium. Concerns mounted in 1972 over whether established sources of new platinum could supply all the requirements for emission control devices that would be forthcoming with enforcement of new U.S. air quality standards. Producers and processors were active in reassuring potential consumers and Government agencies involved that adequate supplies could be made available if given adequate lead time to expand facilities. A number of provisional supply/ purchase contracts were signed during the year by automakers. Major expansions were underway at yearend.
