WORLD REVIEW 
 
 Estimated world production of barite increased slightly to 6.7 million tons.
The United States produced 11% of the world total and imported 31% of the
world output. 
 Canada.—The Newfoundland and Labrador Department of Mines was
involved
in a number of industrial minerals projects including a major study of their
barite resources.7 The projects were designed chiefly to exploit the areas'
mineral deposits. 
 China.—The Ministry of Geology and Mineral Resources reported
the
discovery of a barite deposit containing about 400 million tons of recoverable
ore.8 The ore body between the Hunan, Guizhou, and Guangxi Provinces is close
to the surface and easily minable. The Government was pressing to develop
new barite mines to ensure its market shares in the drilling-mud, chemical,
and filler-extender industries.~ 
 Gabon.—The Government was seeking assistance in exploiting its
Bourekiki
barite deposit, which has stated ore reserves in excess of 1 million tons.io
Initial plans called for a $15 million mining operation, with the barite
being marketed mostly in the neighboring countries of Angola and the Congo.

 Greece.—The downturn in worldwide oil and gas drilling activities
forced Silver and Barytes Ores Mining Co. to operate its Kavos and Pikridou
Mines on the Island of Milos on an intermittent basis.~ The facility, capable
of producing 6,000 tons of 3.9 specific gravity filler-grade material, cornpleted
installation of a 12,000-ton-per-year flotation plant to upgrade the ore
to meet drilling-mud specifications. 
 India.—Mineral and Metal Trading Corp. started on its long-range
plans
of diversify-
