The Farmington times. (Farmington, St. Francois County, Mo.) 1905-1926, 1921-12-16

For 1920, 242 ,24S tons of the output
was derived from southeastern and
central Missouri, an increase over
1919 of 1861 tons. The average
metal content Of the lead concen-
trates from these districts was 666
per cent, as compared with 6S.4 per
cent in 1919 The 1920 average value
per ton was $S1.72.
| The quantity of recoverable lead in
southeastern and central Missouri
1920 concentrates reached 161 ,258
tons, an increase over 1919 of 1000
tons. The output was equal to about
"a per cent Of the primary lead
smelted or refined from domestic ores
in the United States in 1920.
Shipments of galena concentrates
from southwestern Missouri totaled
5,937 tons, compared with 7,724 tons
in 1919. The lead carbonate .concen-
trates amounted to 20 tons, an in
crease of three tons. The quantity of
recoverable lead from southwestern
Missouri, the Joplin region, was g.
856 tons, decrease of 2,276 tons.
The average total content of the ga
lena concentrates from southwestern
Missouri was TIT per cent. The av-
erage price per ton was S97,S4 or $751;
OF more than in 1919.
History 1920 Zinc Output.
The quantity of zinc blende concen-
trates sold from Missouri mines in
1920 was 39,431 tons, a decrease of
1882 tons compared with 1919. All
the blende concentrate was produced
| -,
age price received per ton was $45.79,
and the average recoverable zinc con-
tent reported by the sellers was 1916
per cent. The average price received
per ton in 1919 was $40.92, and the
average recoverable zinc content was
5S.5 per cent.
Missouri's zinc carbonate and sill
cate concentrates sold in 1920 amount
ed to 9,494 tons, or 2,247 tons less
than in 1919. The years output was
mainly from southwestern Missouri,
the shipments from southeastern and
central Missouri being only 81 tons,
compared with 231 tons in 1919. The
average metal content of the zinc car
Donate and silicate concentrates was
1913 per cent. The average 1920 price
per ton was $3.50 compared with
$27,33 in 1919.
The combined value of lead and zinc
concentrates from southeastern and
central Missouri in 1920 (Which pro-
duced about SO per cent of the lead
conccntrates) was $19,801 ,299, or 49,
203,746 more than in 1919. The total
value of the southwestern Missouri
lead and zinc concentrates was 49,
626, 1856 as compared with $2,939, Alb
in 1919.
The total quantity of crude ore or
"dirt" mined and treated in 1920 was
6,l08,030 tons. As the total amount
received for all classes of lead and
zinc concentrates sold in 1920 was
$22, 427, 485, the average per ton of
crude ore or "dirt" mined and treated
was 1857, the highest average in
years.
Copper, Nickel, Cobalt, 1920.
Copper, nickel and cobalt occur in
lead ore in considerable quantity in
the vicinity of Fredericktown, and in
small quantity irregularly in nearly
all deep mines. 1t is only near Fred
ericktown that the copper, nickel and
cobalt content of the ore has been the
Iobject of mining. but a concentrate of
these meals has been recovered as a
table middling at several plants in
other parts of the district, and 3,115
tons of copper concentrates were
shipped in 1915, 2,878 tons in 1916,
1904 tons in 1917, and much larger
quantity in 1918, 1919 and 1920.
The lead ore of the southeastern
Missouri carries small proportion of
silver, the average being less than
troy ounce to the ton of lead concen-
trates. The resulting pig lead like
wise carries silver, together with a
little copper, nickel, cobalt and traces
of antimony and arsenic, and is some
times commercially known as "Mis-
souri, chemical" lead in contradistinc-
ton to missouri soft" lead from the
Joplin region.
Silver Output, 1920
The total 1920 Missouri output of
silver was II ,128 ounces, worth $121,-
1870, derived mainly from refining pig
lead. Of this production the cobalt
nickel-copper ores yield 1864 ounces.
About 10000 tons of lead concentrates
yield an ounce of silver for each ton.
Zinc Carbonate Production, 1920
The production of zinc carbonate
from southeastern Missouri in 1920
amounted to 81 tons against 231 tons
in 1919. All the zinc carbonate was
shipped from mines in Franklin, Ore
gon and Jefferson counties.
The quantity of galena recovered
from shallow dippinuS in WaShipoton
and Jefferson counties was only 244
tons. The ore, which occurs at shall
low depths and in association with
barytes, is mined in q small way and
at odd times by the barytes miners.
Nearly all the lead produced in
southeastern Missouri was mined by
the National Lead Co., st. Joseph Lead
Co., Desloge Consolidated Lead Co.,
and Federal Lead Co. The St. Joseph
Co. was the largest producer.
