In Ouray County the Revenue Min
ing & Milling Co., having one of the
largest enterprises In the west, EN-
ploys jigs, Huntington mills and
Wiley tables. An electric plant of
500 volts. furnishes power for the
trolley motor car system of 1900
feet into the mine and distributes
power to motors at different sta
tions in the mill steam plant of
$50 horsepower operates two large
and one small air compressors, The
mill has n capacity OF 45O tons daily
This company has an electric power
plant two miles below, I'm the canon,
using water as initial power, and will
erect at the town of Ouray. on the
Uncompahgre River. another electric
plant of 500 horsepower to supply the
deficiency in winter time at the mill
with the present power equipment
Just down the gulch. about mile
is the Camp Bird Mill, where it is
learned the management is amalga-
mating, concentrating. and cyaniding
Judging from exterior appearances,
the mill has a considerable capacity
Below Ouray miles, may be found
one of the most interesting concen-
trating enterprises in the San Juan
country. 1t is the Bachelor mine and
mill. George r. Hurlburt, j. F. San
ders and C. A.Armstrong, the owners.
have kept one of the lowest-grade
properties operating at all times and
under all conditions, simply by pro-
gress in milling economy. Mr. Hurl-
burt, during the past % years has
devoted much time to the study of
structural and economic geology and
mineralogy and the special condi
tions associated with the occurrence
of ore and ore chutes and channels
and more than all a study of the
economy of milling and value saving.
The Bachelor Mill has capacity of
So tons daily. The mine ships Is to
II cars of crude ore monthly and the
mill produces the same tonnage In
concentrates. The ore is a lead-zinc
sulphide, and much of the heavier
zinc, after being trammed from the
mine more than 1000 feet, is thrown
TO the Gull or waste dump by the ore
sorters. The plan of the mill com
bines crushers, rolls, screens, Bart
lett tables for jig work, and Wiley
tables. The product passing the
Barletts returns to special rolls for
lregrinding to 20-mesh which goes to
water classfers and is distributed to
the tables The tailings from the
Wiltieys go to about 1000 square feet
of canvas, where one man and IA
piece of hose save enough money to
cut an important figure in the oper-
ating expenses. This company con
templates the installation of an cleo
trio plant to get away from steam
and the employment of gasoline
engine.
AT Telluride, in San Miguel coun
lty, the Smuggler and Pandora mills.
under the management of Arthur l..
Collins, are making great strides of
progress. The Smuggler mill. with
so stamps, has thousands of tons Of
tailings pitted and is just complet-
ing cyanide plant of $50 tons capac-
ity. The Pandora. under the same
ownership, superintendent by Thorn
as Elliott, is adding from 40 to so
stamps, with the required number OF
vanners and Wilfeys, and will soon
be contributing its share of tailings
to the big cyanide plant. The Snug
gler uses crusher, rolls and stamps
humping tables. Chilian mills, and van
ners, and sends what is left to the cy-
anide plant. All the pulp first pass
es over the amalgamating tables.
The Pandora has the same process
, except the Chilan mills. The Pan
dora crew is progressive. Every ta-
BILE and battery man, from the super
intendent down, reads Mines and Min,
. erals, and employees the Coal and
| Metal Miners Pocketbook" for ref.
, erence.
One of the ideal mills of the west is
the Liberty Bell. at Telluride. Here
amalgamation, concentration, and cy-
anidation are very perfectly compre
, hended under one big roof. and q
shines plant 60 #. X 400 it. is now in
course of construction. Two practic
, al men, Superintendent Chase, and
Professor Bell, the cyanide man, ap
| pear to have this vast enterprise un
r der control to a detail. The ore is
, received after being crushed at the
, mine, at the top or tram station OF
i the mill passing from bins to sever
; al batteries of stamps, over amalgan
, plates and tables and to cyanide vats
, of 2S5 tons capacity to the charge fol
5 each vat Wilheys, single and doubl,
deck, are employed in concentra
5 ton. The tailings, having an aver
) age of 81 per ton, are treated by cy
2 anide at 55 cents per ton. The mil
! employs both water and electric pow
e er. There are so stamps of 85i
|. pounds each with 6-inch drop. There
= are 5 settling or charge watts, 80 fee
r in diameter s feet high. and of 2S'
i tons capacity each, The shines plan
y will handle the cyanide tailings.
/. The Peck cyanide mill. which ha
J. been working on $50 tons capacit.
l. on leased tailings for about years
;. continues operation successfully. Thi
n is strictly cyanide proposition ol
h the close margin of tailings.
