“…Estimates of antici pated cumulative production of lithium in the U.S. to the year 2000 are on the order of 400,000 tonnes (Vine, written commun. Feb. 1975;Borg and O'Connell, 1976). This supply is adequate to meet the demand for lithium in glass, ceramics, aluminum, fluxes, greases, etc., but clearly, any additional demand, such as exten sive use of lithium in automotive batteries or in a fledg ling controlled thermonuclear reactor industry, will tax existing reserves and resources which are on the order of 320,000 and 830,000 tonnes respectively (Vine, writ ten commun., July 1, 1975).…”
