DOMESTIC PRODUCTION Domestic cadmium metal production in 1979 increased slightly over that of 1978; however, production during, both years failed to reach levels achieved during 1976 and 1977. In mid-December 1979, St. Joe Zinc Co., a major producer of zinc and byproduct cadmium, announced the permanent closure of its electrothermic zinc smelter at Monaca, Pa. The company was studying the feasibility of replacing the Monaca facility with a new electrolytic smelter at an unspecified location. In 1978 recovery of cadmium metal averaged just over 4 kilograms per ton of slab zinc produced in domestic smelters, compared with an average of 4.8 kilograms recovered between 1973 and 1977. Recovery of cadmium in domestic smelters between 1964 and 1973 ranged from 4.2 to 6.3 kilograms per ton of slab zinc. During 1979 production of cadmium com-~ pounds other than cadmium sulfide (cadmium content), which includes both electroplating salts and cadmium oxide, increased over.that of 1978. The quantity of cadmium produced under this category has, with a few exceptions, registered a steady increase in recent years. Production in 1979, for example, was 30 times greater than that of 1971. Cadmium oxide was produced at two primary-metal-producing plants. Data on cadmium oxide production are not published to avoid disclosing company proprietary data. The production of cadmium sulfide (including cadmium sulfoselenide and lithopone) during 1979 registered a significant increase over 1978 production.

CONSUMPTION AND USES The apparent consumption of cadmium in 1978 was 18% greater than that of 1977, and in 1979 was 7% greater than that of 1978. Though actual consumption data are not gathered by the Bureau of Mines, the distribution of apparent consumption during
