Carlin, Jr.,1 and Robert J. Bascle1 Domestic consumption of bismuth was 2.5 million pounds in 1978 and 2.7 million pounds in 1979 compared with 2.4 million pounds in 1977. Imports increased in 1978 because of greater domestic consumption and lower production. Exports in 1979 were over four times those of 1978, while imports declined by 18% because of higher domestic production. The domestic producer price for refined bismuth fell from $4.50 per pound to $2.50 per pound in 1978, but by yearend 1979 was $3 per pound. World bismuth mine production was 9.7 million pounds in 1978 but fell to 9.4 million pounds in 1979. Legislation and Government Programs.—Throughout 1978 and 1979, Government stocks remained at 2,081,298 pounds, including 567,186 pounds in the national stockpile and 1,514,112 pounds in the supplemental stockpile. The stockpile goal of 771,000 pounds for bismuth remained unchanged, and no action was taken to dispose of the 1,310,298 pounds of excess. Federal income tax laws provided a percentage depletion allowance of 22% for domestic production and 14% for U.S. companies producing from foreign sources. DOMESTIC PRODUCTION Bismuth was produced almost entirely and Smelting Co., Franklin Park, Ill., refrom the treatment of lead ores and bullion covered a small quantity of bismuth by of both foreign and domestic origin.

United Refining CONSUMPTION AND USES A significant increase in bismuth usage in continued strong economy, especially in the the metallurgical additive category from various specialized end uses for which ma!1978 to 1979 was largely attributed to a leable iron castings find application.
