was used principally for roadstone. Dimension stone granite increased in
volume and value over that of 1966 while crushed granite decreased 41 percent
in output and 18 percent in value. Overall granite pro. duction decreased
31 percent in quantity and increased 17 percent in value. Miscellaneous stone,
reported from Rensselaer and Clinton Counties, increased 22 percent in tonnage
and 16 percent in value; it was used mostly for roadstone and concrete aggregate.

 
 Talc—The quantity and value of talc mined was less than in 1966. However,
New York continued to be the leading talc-producing State. Two companies
mined talc from three underground mines and one *open cut mine in St Lawrence
County. Crude talc was ground in: company-owned mills and marketed principally
for use in ceramics and as a mineral filler in paint. Small quantities. were
used in floor and wall tiles, rubber, and as a mmerial filler in other products.

 
 Vermicullte.—Crude vermiculite mined in other States was exfoliated
at a plant in Weedsport, Cayuga County. The expanded material was used for
loose fill insulation, agriculture, ultralightweight concrete aggregate,
and building plaster aggregate. 
 
 Wollastonite.—Crude wollastonite was mined and beneficiated at the
Willsboro Mine in Essex County by the Oxides Division, Cabot Corp. The operation
received a citation from the National Safety Competition in the Underground-Nonmetal
Group for having had no disabling work injuries during 1967. The refined
material was used as a filler in paints and plastics and as an ingredient
in ceramic products. 
METALS 
 
 Aluniinurn,—Production of primary aluminum from the Massena plants,
St. Lawrence County, of Aluminum Company of America and Reynolds Metals Co.,
increased slightly in both tonnage and value over than of 1966. The State
continued to rank fourth in aluminum production. 
 
 Iron Ore.—Mine production of magnetite iron ore decreased 9 percent
from two underground mines, one each in Essex and Clinton Counties, and two
open pit mines, one each in Essex and St. Lawrence Counties. One underground
mine at Chateaugay, Clinton County, operated by Republic Steel Corp. closed
permanently June 30. Production of copcentrates decreased 14 percent, but
mill concentrate stocks still increased. All of the ore was beneficiated,
and most of the concentrates were agglomerated before shipment. Shipments
were principally for use in the manufacture of pig iron and steel, but some
quantities were also used for the manufacture of cement, for heavy media
separation, and for ballast. 
 
 Lead.—Sharply increased quantities of lead were recovered as a byproduct
of zinc mining at the Balmat mine in St. Lawrence County. Production and
value increased 51 percent and 40 percent, respectively, compared with 1966.
Recovery of lead has varied from year to year, depending on the proportion
of ore coming from that section of the Balmat mine where the vein has a higher
lead content. The lead concentrate was shipped to the company's lead smelter
at Herculaneum, Mo. 
 
 Silver.—The quantity of silver recovered from lead concentrates shipped
