260  MICHIGAN—19cCounties in west- central Michigan. Total output
slightly from that of 1989, but the State continued as the leader among six
producing States and, in 1990, provided most of the Nation's output. Compounds
produced included caustic-calcined magnesia, magnesium carbonate, magnesium
hydroxide, and refractory magnesia. Dow Chemical Co. also produced small
amounts of unpurified bromine as a byproduct of magnesium production at its
Ludington plant in Mason County. The material was shipped to Arkansas and
reprocessed for consumption. 
 Peat.—Michigan continued to lead the Nation in peat sales, ranking
first among 22 producing States ~ in 1990 and supplying one-third of the
U.S. total. Eleven companies sold 280,000 short tons of peat from bogs in
10 counties. Although sales declined about 2 % from the 1989 level, a $1.
10 per ton increase resulted in a 3 % growth in total sales value. 
 Reed sedge was the predominant type produced, with smaller quantities of
humus and sphagnum also reported. About 89 % of the sales was for general
soil improvement. The rest was used as an ingredient in potting soils; for
mushroom beds; on golf courses; by nurseries; for vegetable growing; packing
lowers, plants, shrubs, etc. ; and as an earthworm culture. Two-thirds of
the product was sold in packaged form; the remainder, in bulk. 
 Pen'iie (Eqxmded)..—Crude perlite from Harborlite Corp. ' s mine
Arizona was expanded at the company's Vicksburg plant in Kalamazoo County.
Sales and value approximated those of 1989. The expanded product was marketed
for use in filter aids and fillers. 
Potassiwn &zl/s.—Kalium Chemicals Ltd. completed the first
year of operation at its pilot plant facility in Hersey Township in southwestern
Osceola County. The company produced potash by solution mining of an ore
body, which was 2,400 meters deep. No specific plans 
were announced by Kalium for further 
expansion of the 36,000-metric-ton-per- 
year test facility that was constructed to demonstrate a technical ability
to extract 
 and refme potash from the Michigan Basin. 
 SaiL—Salt was solution-mined by Akzo 
Salt Inc. in Manistee and St. Clair Counties and by Morton International
Inc. in Manistee County. The vacuum pan 
 process was used at each of the operations to obtain the salt from the brine.
Michigan ranked eighth among 14 producing States. Sales increased about 
 5 % in quantity and 9 % in value. Salt was sold for a variety of uses, including
animal feed, chemical-industrial processing, highway deicing, human consumption,
and water treatment. 
 Sand and GmveL—Construction.- 
~ Construction sand and gravel production 
~ is surveyed by the U.S. Bureau of Mines 
~ for even-numbered years only; data for odd-numbered years are based on
~ company estimates. This chapter contains 
~ actual data for 1988 and 1990 and 
~ estimates for 1989. 
~ A record-high output of construction 
~ sand and gravel was reported in 1990, 
~ with tonnage and value increasing 12% 
~ and 16 % , respectively, over 1989 
~ estimated figures. It accounted for 11% 
~ of the State's nonfuel mineral value; only 
~ iron ore and portland cement contributed more. Michigan again ranked second,
~ behind California, among the producing 
~ States. In 1990, 240 companies and government agencies reported production
~ from 314 operations in 72 of the State's ~ 83 counties. Table 3 provides
production and end-use data for construction sand and gravel from each of
the State's three districts depicted in the State map. 
Induslrial.—Compared with 1989 figures, industrial sand production
19 % in quantity and 22 % in value to its lowest level in many years. Michigan
ranked third among 38 producing States, yielding to California the second
place ranking it had held for 10 years. Illinois continued as the number
one producer. Seven companies reported output from 14 
operations in 1 1 counties, mainly from coastal dunes along Lake Michigan.
Each of the companies sold sand for foundry applications, a use which consumed
about 92 % of the production. The remainder was sold for glassmalcing, fiberglass
manufacture, sandblasting, refractories, traction sand, and other miscellaneous
 Slag, lion and SteeL—Michigan ranked fourth among 28 States processing
iron and steel slag in 1990. Only Ohio, Indiana, and Pennsylvania, respectively,
reported greater sales. Two companies processed iron and steel slag from
steel mills in Wayne County and electric arc furnaces in Jackson and Monroe
Counties. The material was marketed 
mainly for road base material, with lesser amounts for a variety of other
uses. Sales increased 7 % in quantity and 9 % in value. 
 Stone.—Stone productionis surveyed by the U.S. Bureau of Mines
oddnumbered years only; data for evennumbered years are based on annual company
estimates. This chapter contains estimates for 1988 and 1990 and actual data
for 1989. 
 Crt~1~d.—Sales of crushed stone by Michigan producers were estimated
at 43. 1 million short tons, about 5 % above 
1989 sales and the highest since 1974 when sales neared 47.5 million short
tons. Attendant value increased about 4% to $129 million, a record high.
Limestone-dolomite constituted more than 90 % of the crushed stone sales,
with marl, sandstone, traprock, and quartzite accounting for virtually all
of the remainder. Although Michigan ranked only 12th among the 49 States
producing crushed stone, it is the site of some of the Nation's largest quarries.
Based on 1989 data, the average output of the State's 30 active limestone-dolomite
quarries was 
1.3 million short tons, compared with a national average of 322,000 short
