with little prospect for improving the plant's competitive position in the
near future. The same problems, together with rising costs and freight rates,
faced all producers of these alloys. 
 Electrolytic Manganese Metal.—All of the manganese metal produced
domestically and virtually all of that imported was electrolytic metal. Virtually
all of the metal consumed was electrolytic metal, although some low-carbon
ferromanganese (such as the domestically produced "Massive Manganese"
or
the imported "Gimel Metal") and some manganese-aluminum additives
may have
been erroneously reported by consumers as manganese metal. The metal 
that was used to make manganese-aluminum additives is included in table 4
under the "Alloys (excludes alloy steels and superalloys)" category.
These
additives are not knowingly included in the table, it being desired to report
consumption at the metal rather than the additive level of the usage cycle.
 Production of electrolytic manganese metal increased to 24,390 short tons
from 23,966 tons in 1976. Production was by the same three plants of the
same three companies: Foote Mineral Co., New Johnsonville, Tenn.; Kerr-McGee
Chemical Corp., Hamilton (Aberdeen), Miss.; and Union Carbide Corp., Marietta,
Ohio.
