1287Vanadium By Harold A. Taylor, Jr.1 Domestic demand for vanadium was still weak in 1972, compared to the high of 1969, although it was stronger than last year. Overseas demand was also weak but becoming stronger. Domestic production, expressed as vanadium pentoxide recovered, did not change significantly from last year because the production decrease resulting from the shutdown of the Rifle mill was balanced by increases in output at other facilities. Exports of both ferrovanadium and vanadium ores and oxides were much smaller than in 1971, while imports of ferrovanadium were much larger. The Government sold all of its surplus vanadium pentoxide in May. Legislation and Government Programs. —The General Services Administration (GSA) sold all its excess vanadium pentoxide, 5.6 million pounds, to three metal trading firms in May. A condition of sale was that the material could not be sold abroad as vanadium pentoxide. It must be converted to another vanadium product in this country in the event of export. The material sold consisted of 87 lots, the vanadium pentoxide contents of which ranged between 85% and 90%. As of December 31, 1972, the Government had an inventory of 2,800 short tons of vanadium, the entire quantity in the national stockpile. Of this total, 1,200 tons was held as ferrovanadium and 1,600 tons was held as vanadium pentoxide.

DOMESTIC PRODUCTION The principal domestic source of vanadium continued to be the Colorado Plateau uranium-vanadium ores, but by an even more slender margin than in 1971. Both Arkansas vanadium ore and Idaho ferrophosphorus supplied an increased amount of vanadium. Most of the produc ing facilities processed such materials as vanadium-bearing oil residues, spent catalysts, vanadium-bearing residues from titanium dioxide production, and foreign vanadium-containing slags.
