creased 18% compared with that of 1971; 77% was classified as refractory-grade
and 
23% metallurgical-grade. Exports of refractory-grade chromite totaled 314,229
tons. The United States received 47%, Japan 15%, and the United Kingdom 12%;
the balance was shipped to nine other countries. Japan received all of the
75,919 tons of metallurgical-grade chromite exported. 
 Rhodesia, Southern.—United Nations economic sanctions, which were
applied in 1966, brought retaliation by the Rhodesian Government in the form
of an embargo on mining news, primarily production data. Firm production
data has been unavailable since 1965. 
 Rio Tinto (Rhodesia) Ltd. (RTR) reportedly - requested government approval
for building a chromium smelter complex at Eiffel Flats near Gatooma. Production
could occur in 1975 depending on world demand and government approval. The
company was also considering using the facilities as a custom smelter. In
preparation, RTR acquired the total share capital of Rhodesian Mining Enterprises
Ltd. and the claims and assets of Great Dyke Chrome Mines Ltd. Rhodesian
Mining had two mines in operation, the Jester and Feoch mines, and the O'Meath
mine on standby. Great Dyke Chrome mines held a large number of claims in
the Darwendale area of the Great Dyke. RTR also had an option to purchase
the entire share capital of Frances Mines Ltd. 
 South Africa, Republic of.—Chromite production in the Republic of
South Africa totaled 1,635,000 tons and was down 10% compared with 1971 figures.
Of the total, 504,000 tons was classified as less than 44% Cr203 1,078,000
tons from 44 to 48% Cr203 and 53,000 tons as over 48% Cr203. Local sales
of chromite accounted for 359,000 tons and exports 1,386,000 tons. Local
sales and exports moved in opposite directions compared with 1972; local
sales decreased 19% while exports increased 8%. 
 Despite the downturn of chromite production in South Africa, the Transvaal
Consolidated Land and Exploration Co., Ltd., a subsidiary of Barlow Rand
Ltd., reported annual chromite sales increased for its reporting period ending
September 30. According to the firm's annual report, the group owns a substantial
portion of South Africa's chromite reserves and the combined production of
its three mines makes 
it the largest single producer of chromite in South Africa. 
 Initial work has been completed on increasing chromite production at the
Grasvally Chrome mine owned by African Metal Corp. Ltd. (AMCOR) and operated
by Cromore Ltd. Mining began in 1962 and for the past eight years production
ran about 500 tons per month. The current expansion project when completed
in early 1976 will bring production capacity to 275,000 tons annually, of
which 220,000 will be available for export. 
 South Africa's ferrochromium output received a major boost when the Associated
Manganese Mines of South Africa and United States Steel Corp.'s new plant
at Machadodorp came into production in December. Full production capacity
of the plant will be about 4,409 short tons per month. 
 AM-COR's new chromium ferroalloy furnace was near completion at yearend.
The new furnace with a rat-ed capacity of 50,000 tons of charge chromium
annually will bring AMCOR's total ferroalloy production capacity to 125,000
tons annually, of which 80% will be available for export. 
 Sweden.—Airco Alloys AB, a wholly owned subsidiary of Airco Alloys
and Carbide Div. of Airco Inc., brought onstrea.m a 75,000-kilovolt-ampere
furnace, reportedly the largest in the world for ferroalloy production. Although
being used for ferrosilicon production, the firm also plans on using the
facility for production of ferrochromium. The new unit replaces four smaller
units at the plant and is equipped with a sand filter dust control system
for removing pollutants. 
 Turkey.—Etibank was authorized to develop chromite deposits near Cakmak,
Islahiye, Turkey. The agreement calls for extracting 500 tons of chromite
per year. Etibank also signed similar agreements for development of chromite
deposits at Kirkpinar and Kuzoluk. 
 International Mining Corp., Chrome Resources S.A., and Foote Mineral Co.
joined forces to construct a plant for concentration of chromium ore in Turkey.
Shipments of chromium concentrate were expected to begin late in the year.
 Yugoslavia.—The geology of Yugoslavian chromite deposits was described.5
