BARITE 183 dustries, Chemical Div., New Martinsville, W. Va.; and Sherwin Williams Chemicals, Coffeyville, Kans. PPG Industries closed -the barium plant at -its New Martinsville, W. Va., complex and went out of the barium-chemicals business, owing to depressed markets. Sherwin Williams Chemicals ceased the manufacture of bar-ium carbonate at its Ashtabula, Ohio, plant, but continued to manufacture the product at Coffeyville, Kans. Use of industrial minerals in oil-well drilling muds was reviewed.3 Bari-te and bentonite are by far the most important from the viewpoint of sales value; a variety of other mineral commodities, including lime, soda ash, mica, gypsum, rock salt, and graphite, are also used. The position of barite for mud-weighting purposes seems secure as long as prevailing drilling methods continue.

FOREIGN TRADE Canada and Singapore were the principal countries receiving natural barium sulfate and carbonate exports (mostly ground barite) from the United States. The exports increased from 24,000 tons in 1971 to 52,000 tons in 1972. Imports of crude barite increased 29% compared with those in 1971. The increase can be attributed in large part to the removal of a 10% ad valorem surcharge that was in effect during the last half of 1971. Declared values of crude barite at foreign ports were as follows for the indicated countries: Ireland, - $9.85; Mexico, $10.40; and Peru, $5.47. Imported barite was ground at processing plants in Louisiana and Texas. About 1,300 tons of crushed or ground witherite was imported from the United Kingdom. Imports of precipitated barium carbonate rose over 600%. The large increase was due mainly to reduced domestic supplies of the chemical because of plant closures. West Germany supplied most of the precipitated barium carbonate. Imports of blanc fixe and barium chloride also increased appreciably. Jones, G. K. Industrial Minerals in Oil-Well Drilling. md.
