THE MINERAL INDUSTRY OF PENNSYLVANIA 
687 
 
 Trophy winner in the 1967 Pennsylvania National Safety Competition in the
Quarry Group was the Annville plant, Bethlehem Mines Corp. for operating
468,188 man-hours without a disabling work injury. Other operations competing
in the Quarry Group received Certificates of Achievement for their outstanding
safety record. The top runnerup was the Hanover qvarry, Bethlehem Steel Corp.
with 359,776 man-hours without a disabling work injury, followed by Charmian
quarry, General Aniline & Film Corp. with 205,232 man-hours, and Hillsville
quarry, United States Steel Corp. with 196,442 man-hours. 
 
 Sulfur.—Two refineries recovered sulfur in Delaware County, one using
the Claustype process and the other using singlestage catalytic oxidation
of hydrogen sulfide. In Philadelphia County, one refinery recovered hydrogen
sulfide by the Girdler system using diethanolarnine and monethanolamine and
molten sulfur by the improved Claus-type process, another refinery recovered
sulfur by the Claus process. 
 
 Tripoli. (Rottenstone).—Tripoli was mined and processed by two companies
in Lycoming County for use as an abrasive compound and filler material. 
 
 Vermiculite (Exfoliated).—Crude vermiculite was processe'd at two
plants, one in Bucks County and one in Lawrence County, and the exfoliated
product was sold for various uses, chiefly for insulation, concrete aggregate,
and agriculture. 
 
METALS 
 
 Cadmium.—Cadmium production decreased considerably from that of 1966.
Cadmium was recovered by St. Joseph Lead Co. at its Josephtown plant in Beaver
County and by The New Jersey Zinc Co. at its Palmerton plant in Carbon County.

 
 Cobalt.—The cobalt content of pyrite concentrate shipments from the
magnetic iron ore mines in Berks and Lebanon Counties showed a slight decrease
from that of 1966. 
 
 Copper, Gold, and Silver.—Copper concentrate was recovered by flotation
of magnetite iron ore mined in Lebanon County and shipped to western refineries
for processing. The concentrate also contained gold and silver. 
 Ferroalloys.—Producers of ferroalloys in 1967 by type of product and
furnace were ferromanganese by blast furnace, Bethlehem Steel Co. at Bethlehem,
E. J. Lavino & Co. at Sheridan, and United States Steel Corp. at Clairton
and Duquesne; ferromolybdenum by aluminothermic furnace, Climax Molybdenum
Co. at Langeloth, and Molybdenum Corporation of America at Washington which
also used electric furnaces; ferrocolumbium, Kawecki Chemical Co. at Easton;
spiegeleisen by electric furnace, The New Jersey Zinc Co. at Palmerton; ferroboron,
ferrocolumbium, ferrovanadium, ferromolybdenum, and nickel columbium by aluminothermic
furnace, Reading Alloys Co., Inc. at Robesonia. 
 
 Iron Ore.—Usable iron ore production and shipments decreased 5 percent
in quantity and 9 percent in value from those of 1966. Shipments were in
the form of pellets produced at agglomerating plants located at the magnetite
mines in Beiks and Lebanon Counties. Crude magnetite was mined underground
by block-caving methods. Most of the iron ore pellets were shipped to company-owned
iron and steel plants in the State and in Maryland. 
 
 Iron and Steel.—Pig iron production totaled 20.5 million tons, of
which 92 percent was basic pig iron, and the remainder Bessemer, malleable,
foundry, and direct castings pig iron. 
 
 Receipts of iron ore totaled 26.8 million tons, 68 percent from foreign
countries and 32 percent from domestic sources. Consumption of iron ore totaled
24.7 million tons, 53 percent by agglomerating plants, 41 percent by blast
furnaces, and the remainder by steel furnaces. Iron ore stock at beginning
of the year was 11.3 million tons and 12.2 million tons at yearend. Fluxes
consumed by the iron and steel industry included 2.9 million tons of limestone,
2.5 million tons of dolomite, and 927,000 tons of other type fluxes. Other
materials consumed included 1.6 million tons of mill cinder and roll scale,
889,000 tons of raw flue dust, 1.2 million tons of steel furnace slag, 13
million tons of coke, 336,000 tons of coke breeze, and 383,000 tons of anthracite.
Steel furnaces consumed 19.8 million tons of pig iron and hot metal and 10.5
million tons of home and purchased scrap. Blast furnaces consumed 752,000
tons of home and purchased scrap,
