Information is provided regarding the nature, magnitude, and the extent of the emissions of copper in the United States for the year 1969. Background information concerning the basic characteristics of the copper industry has been assembled and included. Brief process descriptions are given; they are limited to the areas that are closely related to existing or potential atmospheric losses of the pollutant. Emissions to the atmosphere during the year were 13,680 tons. About 64 percent of the emissions resulted from the metallurgical processing of primary copper, and about 20 percent from the production of iron and steel. The combustion of coal was the only other significant emission source.
