The U.S. Zinc Industry: A Historical Perspective.

PB231050

Publication Date	1974
Personal Author	McMahon, A. D.; Cotterill, C. H.; Dunham, J. T.; Rice, W. L.
Page Count	84
Abstract	Changes in world mine and smelter supply sources of zinc have led to changes in zinc supply patterns in the United States during the past 3 years, 1970-1972. There has resulted a growing reliance on foreign sources of zinc metal to furnish an ever-increasing portion of expanding domestic requirements. This review of fundamentals and historical developments is intended to provide background in order to place the future of the U.S. zinc industry in perspective. The properties and uses of zinc are described. A new study on U.S. reserves is presented with description by geographical region and comparisons with older reserve data. The technologies of prospecting through refining are described with emphasis on the metallurgy involved in the various methods of smelting. Production, consumption, and imports are discussed and illustrated with graphs and tables to review the past and present pattern. Government actions affecting the industry are shown. (Author)
