 THE MINERAL INDUSTRY OF OHIO 1 Data may not add to totals shown because
of independent rounding.output and value decreased below that of 1966 and
totaled 1.3 million tons valued at $5.5 million. Average value for industrial
sand increased from $4.07 per ton in 1966 to $4.12. Industrial sands were
sold chiefly for molding, glass manufacturing, and furnace construction and
repair. 
 Producers were active in 68 counties; Franklin, Hamilton, Butler, Montgomery,
and Portage Counties in descending order, led in output. Seven other' counties
had production exceeding 1 million tons. Commercial producers processed 88
percent of the total tonnage by washing, screening, sizing, *or crushing.
Nearly 40.7 million tons of sand and gravel' was shipped to consumers by
truck and the remainder by rail or water. The number of commercial operations
totaled 468; 191 reported production below 25,000 tons and accounted for
41 percent of the total output. Five operations produced from 500,000 tons
to 1 million tons and three operations had output exceeding 1 million tons.

 Fifteen plants were awarded Certificates of Achievement in National Safety
Competition for operating in 1967 without any disabling injuries. Those awarded
certificates were Allied Chemical Corp., Fabricated Products Division, American
Aggregates Corporation (five plants), Blaney Sand & Gravel Co., Inc.,
Dravo Corporation, Ohio Gravel Co. Division (two plants), Hamilton Gravel
Co., Middletown Sand & Gravel Co., Wm. Miller Sand & Gravel Co.,
Seville Sand & Gravel Inc., and Standard Slag Co. (two plants). 
 
 Slag (Iron-Blast-Furnace).—According to the National Slag Association,
processed iron-blast-furnace slag production totaled 
633 
 
5.9 million tons valued at $10.2 million. Output was 4 percent below that
of 1966: 
the average unit price dropped from $1.92 per ton to $1.74 but was greater
than the national average of $1.69. Of the total processed slag, 69 percent
was screened air-cooled material; the remainder consisted of granulated and
lightweight (expanded) slag. Most of the air-cooled slag was used as aggregate
for concrete and bituminous construction, highway and airport construction,
and as railroad ballast; Granulated slag was used chiefly in highway construction
and for manufacturing hydraulic cement. Expanded slag was used chiefly as
lightweight aggregate in concrete masonry blocks and in ' lightweight concrete.
Nationally, the State continued to rank second in production of processed
slag, accounting for 20 percent of the national output. Processing plants
were centered chiefly near steelmaking, facilities in Cleveland, Middletown,
and Youngstown. 
 
 Stone.—Total stone (limestone and sandstone) production increased
1 percent above that of 1966 but vahie decreased by $366,000. The decrease
in value was attributed to less demand for dimension stone. Crushed limestone
production was 1 percent greater and accounted for 98 percent of the total
stone tonnage. Miscellaneous uses of crushed limestone included whiting,
filter beds, stone sand, paper, glass and alkali manufacture, poultry grit,
fertilizer and aphalt filler and for dust abatement in coal' mines. Dimension
limestone production dropped sharply, totaling 6,000 tons valued at $51,000.
Main uses of dimension limestone were in architectural and construction applications.
