PROFITS IN LOW GRADE ORES.
Great Progress Made in Cyanlding Opera
tions With Low Grade Propositions.
The greatest stride which hare
been made in tho gold milling indus
try of late years hare been in connec
tion with low grade propositions.
Tho accomplishments in thin connec
tion aru simply remarkable. Chietly
through the aid of cyanide, vast do
PohIIh of low-grade ore have been
rendered prolltably marketable, where
otherwise they would have been
viiIiiIchh. Not all classes of low-
which II will 1 111 v to reduce in cornice- grade ore can be no handled and tho
tiou with the ordinary smelting ' operation dependH iiIho upon tho eon
proccMM. An arsenic plant Involves dillons under which the depoHltH oo
the nut lay of hiiiiiII capital and can , Mir. Nor Ih it only to cyanide that the
lie operated in conjunction with any lw-Kiiido mining Industry owch its
reduclioii workH where the ores ' success. There are other factor,
Hinelted carrv nrsoiilciil values. It 1 chief among which Ih tho scientific
Ih not probable, however, that the
present smelling company conteiu
pliitos an immediate move 'In IIiIh
direcllon, although it Ik a matter
which, it Ih Mated, Ih likely to come
under future advisement. A well
known milling man Iiiih IIiIh to nay
relative to the subject:
"The production of arsenic. Ih an
ItidiiHtry which Iiiih received but little
attention In IIiIh country, although
not for the lack of adequate condltloiiH
and not hccaiiHo 11 doen not oiror a
prolllable Held for Investment. Huielt
1 us; cniiipaii,los In the past have In
fact passed the matter up without
any serious consideration. In the
Sumpter district there in plenty of
ore carrying arsenclal values, and
since the process of reduction Ih simple
and involves but hiiiiiII expense
operated in connection with a smelt
ing plant, there Ih no reason why the
present smelter people should not,
In time, Install such a plant.
Arsenic Ih an article of commerce
used largely In the manufacture of
glass paKir, calico printing and also
hi medicine. It Ih extracted from
the ores by a process known as
sublimation, which consists of allow
ing the arsenical vapors from the
smelter to cool in brick chambers
where the metal Ih precipitated in the
form of a grayish powder. Thin
powder Ih thou roast ml and the filings
driven Into a separate set of chambers
where the arsenic attain sublimes In
an almost chemically pure form.
These chambers till several times
a year, deluding upon the character
of the ore and the capacity of the
plant. The arsenic collects In- a
grayish crystalline form practically
tilling the openings. It in then
taken out, pulverized and Ih ready
for shipment.
"The plant Itself Ih very simple,
tho chamlier tioliig usually construct
ed of brick, having an aperture
something like Ox (J feet with doom
at Intervals for taking out the arsenic,
and coniiiiuiilratliiK with a stack for
carry Iiik "If tho vapors. Tho
anon leal fumes from tho smelter
itra usually conducted underground
to tho Unit set of chambers where
th metal is deposited in tho crude
form. Ouly three or four mou work
ing on shifts are required to keep
the plant gong. "
Thorn Is at present only one arsenic
plant in the United States, ami this
is run lu oouuootlou with tho Puget
and economic systems of operation
which have been devisd.
The matter of the cyiiuidlng oper
ation Ih very interesting. Prof.
Merrill, the cyanide authority, re
cently said: "The average value of
the sand treated In 1111)2 was 81.05
per ton. The average cost of cyan
ide treatment was .115:1 cent per ton.
The average percentage recovered in
bullion by tho treatment during tho
past six months wiih 7-1.7. The
slimes carry an assay value ranging
from 80 cents to 81.10 per ton.
"The maximum monthly tonnage
of this plant wiih attained lu October,
1 !)()-, when 1(),'2:I0 tons, or 121)8
tons per day, were treated. Tills
gives to tho lloinestako company tho
Ingest sand treatment cyanide plant
In the world, th uext largest being
I lielivee, that of the Simmer and
Jack, in South Africa."
The Hoinestake company lms cer
tainly accomplished wonders In
the matter of mining and treating
low-grade ore. Nor Iiiih tho com
pany followed a seltlsh or niggardly
policy. From time to timo tho world
is told of what Ih being done and
how it Ih being done. Journal and
