MINERALS YEARBOOK, 1967 
 
 Lead and Zinc.—Production of zinc increased about 17 percent in quantity
and 12 percent in value. Wisconsin producers supplied about 5 percent of
the Nation's mine production of zinc in 1967, ranking seventh in production
of this metal. Lead output declined 6 percent in quantity and 13 percent
in value. 
 Average yearly weighted prices of lead and zinc were 14.00 cents per pound
for lead and 13.84 cents per pound for zinc, compared with 15.12 cents for
lead and 14.50 cents for zinc in 1966. 
 Lead and zinc were produced in Grant, Iowa, and Lafayette Counties. Companies
operating mines and mills throughout the year were American Zinc Co., Eagle-Picher
Industries, Inc., and Ivey Construction Co. The New Jersey Zinc Co. began
production of lead and zinc concentrates in May at its new mill near Elmo.
The flotation mill has a capacity of 800 tons of crude ore per day. Crude
ore for this operation was supplied by the company's nearby Elmo mine. Muffin
Mining Co. 
shipped crude ore for custom milling. Eagle-Picher Industries, Inc., closed
its Kennedy mine near Hazel Green in January. The company also discontinued
milling material from "boulder piles" from the Old Mulcahy mine near Shullsbuig.
American Zinc Co. ceased operations at its Burnham mine in early 1967.

 Sales of lead concentrate by Wisconsin producers during the latter part
of 1967 were prevented by a strike at the American Smelting & Refining
Co.'s El Paso, Tex., smelter. American Zinc Co., Eagle-Picher Industries,
Inc., Ivey Construction Co., and The New Jersey Zinc Co. conducted exploration
and development activities including drilling, underground development, electromagnetic
surveying, induced polarization, and geochemical sampling of spring water.
Some exploratory drilling was discontinued because of the drop in price of
lead and zinc. 
 Tailings from several lead-zinc milling operations were used for road construction,
railroad ballast, and agricultural purposes. The Federal Bureau of Mines
awarded a grant to the University of Wisconsin for a 2½-year research
program to investigate 
the possibility of recovering burnt dolomitic lime, usable as flux in steelmaking,
from lead-zinc mining and milling wastes. 
 
MINERAL FUELS 
 Peat.—Output of peat decreased 23 percent in quantity with a lesser
decrease recorded for value. Major reason for the decrease was a decline
in sales of peat used for general soil improvement and seed inoculant. Peat
was produced by three companies in Lincoln and Waukesha Counties; one company
produced only moss peat, one humus peat, and one produced both types. Most
of the peat was shipped in packaged form. Major uses, in decreasing order
of quantity, were seed inoculant, general soil improvement, packing shrubs
and other plants, and as an ingredient for potting soils.
