The WoRDENHoFF MILL
Extensive Machinery for the
Big Creek Property.

/
The Colorado Iron Works Co.
has been awarded the contract for
building the milling plant that is
to be erected this fall on the Wor-
denhof mine in Idaho's Big Creek
mining district. The batteries
will consist Of thirty stamps, in
stead OF twenty, as was first given
out, and the specifications call for
an amalgamation and cyanide
plant, with complete equipment
for operation either by steam and
water power, an electric lighting
plant, complete assay outfit, and
q sectional sawmill. When the
erection Of the buildings and the
installation of the machinery has |
been completed this will constitute
one. OF the most thoroughly modern
plants in the west. 1t is expected
that it will be ready for operation
by November 1st.
The saw mill will be sent in inn
mediately, hauled in by freighters
from Emmett to the present termi-
nus of the wagon road, and packed
from that point to the mine on the
backs of mules, the contract calling
for the various parts tc be section
allied with the view of this method
OF transportation. 1t will have a
capacity Of twelve thousand feet
of lumber per day, and will handle
any size timber up to four feet in
diameter. 1t will be operated by a
thirty-horse power engine and
boiler, entirely separate and dis
tinct from the power system Of the
main milling plant, and will run
two saws simultaneously, inclu-
ding a cross-cut saw for shaping up
dimension timbers and for cutting
whatever wood it may be found
necessary to use as fuel. This
equipment will be sent in to the
mine as soon as the trail is open
!, and a large force Of men will at
!, once be put to work getting out
: lumber and the heavy timbers re-
E quired in the construction of the
I mill buildings.
] The mill itself will consist Of six
I batteries OF five stamps each, OIL
: thirty stamps in all, each of which
e will weigh 1000 pounds. Stand
: ard Blake rock crushers ane
challenge Eclipse ore FEEDER
will be used. The stamps will b,
dropped ninety times a minute
; and the mortars will be of tn
Homestake pattern, nine and on
It half inches thick under the dies
l. Screen frames will be of wood
II held in place by wrought iron keys
! The stamp stems will be tapered a
: both ends, SO that should one breal
= the stem could be reversed and tn
v other end used. In addition to tn
a. regular equipment required extr
,e parts will be supplied.
a. In the cyanide department fifteel
d tanks are to be constructed, of til
u following dimensions: Two tank
- IL feet in diameter by 10 feet deer
No. 10 steel solution tanks; 81
~ steel teaching tanks, 80 feet in d
,e ameter by five feet deep; two gol
er solution tanks, of No. II steel, l
be feet in diameter by feet deel
re two steel stump tanks, % feet in d
In ameter by 6 feet deep; one lea
a lined acid tank, one slime pres
n n tank, and one 15-chamber filtt
y. press. Additional equipment ft
n. this department will comprise ]
to filters, 30 gallons Of acid proof con
he pound paint, four - compartmel
es. zinc boxes, six centre dischare
in valves, complete iron work IL
on one muffle roasting furnace, an
40 also for one melting furnace, 81
on crucibles, Stag moulds, bullio
he moulds, complete hoist with tro
de ley and track, zinc lathe, distril
in. utor, and all necessary piping
e." The distributor will operate ant
In matically, SO as to uniformly e
10 each of the teaching tanks.
ne The power plant will consist
~ two Co. horsepower boilers, one 8
IL horsepower Tangye-bed engin
At. one 2O-horse-power automatic e
led CINE, and one foot standard Pc
Of ton water wheel which, under
ely 400 foot effective head, will gen
My lrate 24O horsepower with $50 re
ust olutions per minute. Addition
equipment will consist of two fe
tns water injectors, one hundr
horsepower vertical pattern tubul
feed water heater, one duplex DO
er feed pump, one duplex soluti'
ev- pump, and 1900 feet of sheet ste
the rivet pipe, for conducting wat
OF to the Pelton wheel.
Oh v The electric lighting plant W
nh be as completely equipped as tn
the of any great city.
&C The assaying plant will be equ
nts ly complete. Nothing that cou
on. add to its completeness will
the omitted, and everything that entt
ma. i INTO its lit of fixtures and suppl
o. will be the best that the mark
