November 17, 1954 Mr. J . D . I cKenzie , Vice President American Smelting and Refining Co ., 120 Broadway, New York City . Dear Sir : Slab Zinc Statistics Following is a revision of report on the above subject made to Mr . McElvenny on February 20, 1947 . This carries Slab Zinc statis- tics through the year 1953 . Attached you will find : t . Tabulation giving salient statistics for the period 1900- 1953 with accompanying key to same . 2n . Graphic chart with indicated trends in production and con- sumption of zinc over the present century as well as description of graph . This study has been made with the idea that past statistics might serve as indication of the metal's future, particularly as to its sales price . Since the world's supply of zinc and lead is, in general, de- rived from the same ores, a brief review of the relative history of the two metals is of interest For the period 1900-1943 the E . St . Louis price of zinc averaged 6 .18 cents while for the same period the N . Y . price of lead aver- aged 5 .50 cents . For the period 1924-1943 the world's average pro- duction of zinc was 1 590, 000 tons per year while the average pro- duction of lead for t .e same period was 1,690, 000 or slightly higher than zinc . As the ratio of zinc to lead tends to increase in the ores it would appear that it will become more difficult to market zinc at a satisfactory price particularly in view of the future competition of zinc with the world's rapidly increasing aluminum output . Referring to the graph it will be noted that for the period 1900-1929 U . S . was an exporter of zinc ; forte period 1930-1937 -2- U . S . was self-sufficient ; and from 1938 to date imports have rapidly increased, this being explained by decreasing primary domestic pro- diction and increasing consumption . 'he peak of domestic primary and redistilled second production, as indicated on the graph in Orange, was reached in 1941 followed by a slight decline until 1951 . Since then the future of the domestic in- dustry looks very uncertain but production, in competition with low cost foreign supplies, will probably continue t o decrease . Domestic consumption as calculated from domestic production of primary, plus redistilled secondary, plus excess of imports and cor- rected for annual inventories, is indicated by the full Purple line . This does not, however, take into account the slab zinc imports for Government Account, which were approximately as follows : 1950 - 123,256 tons 40,6696 6 It 1995 1953 - 62,,270 a The dotted Purple line is intended to show trend of consumption after allowing for excess stocks in G .S .A . stockpile . The domestic trend of a primary production of 520 000 tons in 1960 r with an estimated consumption of 1,®x0 , 000 tons in 1966 would indicate 1960 import requirements of foreign slab and recoverable zinc in con- centrates in the amount of 560,000 tons . It is rather difficult to indicate the trend of the future world*s slab zinc production as this appears to have a very large potential capacity . This is indicated by the rapid recovery of the industry after World War I and the Depression of the Thirties . The great increase in output since World War II is also noteworthy . In the last eight years world production has increased from 1,454,997 tons in 1945 to 2,603,316 tons in 1953 . The production of 2,603,316 tons in 1953 with corresponding U . S . imports of 666,585 tons looks rather disturbing . The origin of these imports is as follows : Recoverable Slab Zinc Zinc As Ore Total Canada 108,000 tons , 04 tons 252 6 tons Mexi co 34 , 0000 141 ,000 175,000 Europe 780000 26V000 1014 000 Peru 8,000 70,000 78,000 Australia 4,000 9,000 13,000 Others 000 42 .000 000 35,000 " 432,000 6 7,000 ' Just where the large foreign output is to find a market when the 0 . S . A. stockpile has reached its limit appears to be a problem . Some possi- bilities along this line are : t . If the European automobile industry expands materially there There are possibilities in the increased use of rolled zinc sheets of light weight for roofing,, where these have been strengthened by alloying with very small amounts of titanium and copper . Everything considered, however,, the prospects of an improved world price for zinc do not appear to be very bright . Yours very truly, . Fleeting 0 /s/ E .
