A. Cammarota, Jr.2 The consumption of antimony declined in 1978 and 1979 from that of 1977. For the fifth consecutive year, the use of antimony metal as a hardening agent in battery grid alloys decreased. Technological changes in the types of alloys used in automotive batteries have drastically reduced the use of antimony as a hardener for battery grids in recent years. The traditional practice of pricing antimony metal on the basis of RMM and Lone Star brands, which were produced at NL Industries, Inc.'s, Laredo, Tex., smelter, was discontinued in April 1978 owing to the closing of the plant and depletion of residual stocks. Effective April 17, 1978, a new quotation was established on the basis of refined antimony in alloy. The new price, $1.75 per pound, represented the published prices of the two largest alloy producers, NL Industries and RSR Corp. This price was maintained through early 1979, when it was increased to $2 per pound, remaining~ at that level through the year. Domestic mine production was at normal levels in 1978 and 1979, but metal production increased substantially in 1979 over that of 1978 because of the reactivation of the smelter in Laredo, Tex. Imports were up significantly in 1978 and 1979 over those of 1977, mainly because of higher imports of concentrate and antimony oxide. Legislation and Government Prograrns.—At yearend 1979 the General Services Administration reported that Government stocks of antimony totaled 40,727 tons. The Government stockpile goal remained at 20,130 tons. MINE PRODUCTION mony Corp. (TJSAC) produced antimony from the stibnite mined at the Babitt, Bar- Domestic mine production of primary antimony in 1979 by two companies was down dot, and Black Jack mines at Thompson from that of 1978.
