ZINC The Zinc Institute Inc. conducted a survey of 460 diecasters to determine the market distribution of the 418,319 tons of zinc die castings shipped by these companies in 1977. The results showed that automotive components accounted for 49.3% of the total; builders' hardware, 22.4%; domestic appliances, 5.4%; industrial, agricultural, and commercial machinery, 5.9%; electrical components, 9.3%; sporting goods and toys, 2.5%; scientific and professional equipment, 1.4%; sound and television equipment, 1.4%; and miscellaneous, 2.4%. Since inceptioh of the survey in 1974, the data indicate that builders' hardware and electrical components increased their market share from 25.5% to 31.7%, while the share taken by domestic appliances and industrial, agricultural, and commercial machinery declined from 16.0% to 11.3%. ZINC PIGMENTS AND SALTS Production.—Production of zinc oxide in 1977, at 207,725 tons, increased 7% over that of 1976. Shipments were 1% higher than production. The source of domestic zinc oxide production was 54% from ore and concentrate (American process), 26°% from slab zinc (French process), and 20% from secondary material. Total French-process zinc oxide, including that from remelt and scrap, was 33% of the total. Lead-free zinc oxide was produced at 13 plants in the United States, and leaded zinc oxide was produced at 1 plant. Zinc sulfate production, at 38,818 tons from nine companies, showed an increase of 12% over that of 1976. Zinc sulfate production came from secondary material and from ore or intermediate products. Zinc chloride production from four companies was 13,913 tons; 14,007 tons was shipped. St. Joe produced 50,201 tons of zinc oxide, down 4% from that of 1976, and ASARCO, with plants at Columbus, Ohio, and Hillsboro, Ill., produced about 32,000 tons, down 11% from that of 1976. New Jersey Zinc also produced zinc oxide from ores or concentrates, and slab zinc. Other major zinc oxide producers such as the Eagle-Picher, Hillsboro, Ill., plant and the SherwinWilliams Co., Coffeyville, Kans., plant, used calcines, fume, and secondary materials as raw materials. New Jersey Zinc and St. Joe were the two largest of the six producers of French-process zinc oxide. Consumption and Uses—The apparent 999 consumption of zinc oxide increased 5% in 1977 to about 224,000 tons. Analysis of domestic shipments by industry usage showed the largest consumers to be the rubber industry with 54% of the total; chemicals, 14%; photocopying, 11%; and paints, 7%. The use of zinc oxide increased for rubber, agriculture, and miscellaneous uses. Photocopying declined 3%, continuing the downward trend of recent years. Among miscellaneous uses, zinc oxide was used in floor coverings, fabrics, lubricants, plastics, and rayon manufacturing. Agriculture was the chief use for zinc sulfate with lesser amounts assigned to rayon, flotation reagents, and chemicals. Leaded zinc oxide was used in rubber, and lithopone was used mainly in paints. MOst of the zinc chloride was used in soldering fluxes and batteries. Prices—List prices at the beginning of the year were 40 cents per pound for American-process, lead-free, pigment grade, 41.5 cents for French process, regular, 43 tO 44 cents for electrophotographic grade, and 38 cents for zinc oxide, leaded, 12%. With the reduction in the price of zinc metal in May, U.S. producers lowered zinc oxide prices to 37.5 cents per pound for Americanprocess zinc oxide, 39 cents for Frenchprocess, 40.5 to 41.5 cents for electrophotographic grade, and 35.5 cents for leaded zinc oxide. Again in October prices were lowered 1 cent per pound for all grades except leaded zinc oxide, which dropped 1.25 cents per pound. The price Of zinc sulfate, granular monohydrate industrial, 36% zinc, bags in carload lots, was quoted at $24 to $26.50 per 100 pounds. throughout the year. The price of technical-grade zinc chloride, 50% solution, in tank-car quantities, was quoted at $15.25 per 100 pounds in January and at $10 to $17.55 at yéarend. Foreign Trade.—Exports of zinc oxide increased 40% ever those of 1976 to 6,771 tons, of which 4,043 tons was pigment grade. Canada and the Federal Republic of Germany received 71% of the total. Lithopone exports decreased 44% to 435 tons. Imports of all classes of zinc compounds increased m 1977 to a total of 30,154 tons, an 8% gain. As in 1976, zinc oxide was the major component of imports of zinc compounds. Mexico and Canada supplied 93% of the zinc oxide; other European Economic Community countries contributed most of the remainder.
