.OUISIANA—1990  229. according to severance tax data, totaled 1
. 8
million tons. 
 Two conventional surface mines produced sandstone in Sabine Parish and anhydrite
from a quarry in Winn Parish. Shell was dredged from waters in St. Mary and
St. Tammany Parishes. Severance tax data indicated that almost 252,000 short
tons of stone was produced in 1990. 
 Much of the stone used in Louisiana is barged to State ports on the Mississippi
River from quarries in Arkansas, Kentucky, Missouri, and Illinois. Vulcan
Material Inc. shipped stone to distribution yards in the New Orleans area
from a quarry in Mexico's Yucatan Peninsula. 
 Three firms produced a synthetic aggregate to supplement Louisiana's stone
requirements. Louisiana Stone Aggregates Inc. (formerly Louisiana Synthetic
Aggregates Inc.), Geismar; Marine Shale Processors Inc. , Amelia; and Dow
Chemical U.S.A., Plaquemine, produced a useful synthetic aggregate material
from several waste products. Louisiana Stone Aggregates mined and crushed
a solidified calcium sulfate sludge, a waste material from a freon chemical
plant. The material was sold for road construction and agricultural purposes.
Marine Shale produced a nonhazardous (U.S. Environmental Protection Agency
classification) slaglike material during the high-temperature destruction
of hazardous wastes. The byproduct slag was sold for road base and fill.
Dow Chemical's Plaquemine facility operated a medium-Btu coal gasifier. A
byproduct granulated slag was used as an asphalt filler in road surfacing.
 Sulfur.—Once again, sulfur was the State's leading mineral commodity,
accounting for more than 40 % of the 1990 mineral value. Louisiana was one
of two States with Frasch sulfur production and one of 26 with byproduct
sulfur recovery from petroleum and/or natural gas refining. Louisiana's 1.4
million metric tons of Frasch sulfur production ranked it second behind Texas's
2.3 million metric ton output. It is expected that Louisiana will take the
lead in Frasch sulfur output when the Freeport-McMoRan Inc. Gulf of Mexico
property begins production in 1992. 
 Current Frasch sulfur production is from Freeport Minerals Co's. operations
at Garden Island Bay, Grand Isle, and Caminada Pass. Byproduct sulfur was
recovered by seven companies. 
 TitaniumDioxide.—Workwas ongoing on the two largest structures
Kronos Louisiana Inc. ' s (formerly NL Chemicals) Westlake titanium dioxide
complex. By midyear, the chloride process I and finishing buildings were
80% and 30% completed, respectively. Completion of the 90,000-short-ton,
400-plus employee chloride process facility is scheduled for mid-1991. The
new facility will increase the titanium dioxide capacity from 360,000 short
tons per year to 450,000 short tons per year and raise the company's output
from 11% to 13% of the worldwide titanium dioxide industry. Work began on
the $200 million plant in 
 Other Industrial Minerals.—In addition to the commodities listed
table 1 , several minerals were shipped into the State for processing into
higher value products. 
 The Port of New Orleans Public Bulk Terminal was the principal point of
entry for minerals imported into Louisiana. In 1990, 25% of the shipments
through the terminal was metallic alloys, ferrochrome, silicon, manganese,
~ ferrosilicon; approximately 35 % was 
~ "other minerals and sands"; 28%, 
. fertilizers; 7 % , barite; and 5%, miscellaneous ores. The commodities
were imported from Australia, Brazil, China, Ireland, Norway, Republic of
South Africa, Turkey, and ~ 
 Hydrated alumina was imported from Ireland by Alumina Products Inc. for
the production of sodium aluminate. The sodium aluminate was sold to the
aluminum, paper, titanium dioxide, and water purification industries. 
 Anhydrous ammonia was produced by 14 companies for sales to the chemical
industries. The annual capacity of the 
14, in excess of 7 million short tons, was about 40 % of the Nation's capacity.
 Barite, a barium sulfate used in chemical manufacture and oil well drilling
fluids, was obtained from foreign and domestic producers and crushed, ground,
and bagged by Mil-Park Drilling Fluids, Baroid Drilling Fluids Inc. , and
Old Soldiers Ltd. Much of the imported barite, purchased from China, was
shipped through the Port at Lake Charles. 
 Calcined bauxite was imported by Carbo Ceramics, New Iberia. The material
was used to manufacture proppants for the petroleum industry. 
 Synthetic calcium chloride was recovered by Allied Signal Inc. as a byproduct
at its Baton Rouge plant using hydrochloric acid and limestone. Texas United
Chemical Corp. produced calcium chloride from a plant near Lake Charles.
The synthetic material was used to speed concrete setup, for dust control,
in oil and gas drilling, and for road deicing. 
 Garnets were reclaimed by 
International Garnet Abrasives Inc. at a 
10,000-ton-per-year plant in Harvey. 
Garnet concentrates were imported from 
foreign producers. 
 Graphite (synthetic) was used by Reynolds Metals Co. in the production of
carbon anodes at a Lake Charles plant. During the year, work was ongoing
on a $47 million expansion that included a furnace renovation and dock and
ancillary facilities improvements. 
 Perlite was expanded by Filter Media Co. Inc. at a plant in Reserve. The
raw material was obtained from New Mexico perlite producers. Principal markets
were the filter, insulation, and lightweight concrete industries. 
 Phosphate rock for a Geismar phosphoric acid plant was imported from the
Moroccan BouCraa phosphate rock mine. The plant produced super phosphoric
acid for liquid fertilizer. 
 Pumice pebbles from Turkey were imported through the Port of New Orleans
for firms producing "stone-washed" jeans. The pebbles and newly
jeans were machine washed together to producejeans with the "stone-washed
" appearance.
