ore bins of about 5000 tons capacity,
from which the ore is taken to the
sampling mill by belt conveyors.
After sampling the ore is taken again
by belt conveyors either to blast fur
mace storage bins of about 5000 toni
capacity, or to rooster storage bins
of about 5000 tons capacity. From
the blast furnace storage bins the ore
is to be removed by the local tram
ming system in electrically operated
cars. From the rooster bins the ore
will be removed by belt ~onveyors
passing over a conveyor weighing
scale, thence to roasters.
Each rooster building contains
sixteen roasters of the MeDougall
type, ~thirty-two in all, each with a
capacity of forty tons of dry ore in
t~wenty-four hours, the smoke from
the r%oasters passing directly into a
large dust chamber fitted with hop
pers and arranged for the introduc-
ton of the system of wire filters such
as are In use at the Great Falls plant
Of the Anacoda Copper Mining COM
pany, at the expense of merely hang
ing the wires. This dust chamber is
connected by a large flue stack which
Is $50 feet in height and % feet in
side diameter at the eop. The calcin-
ed material from the roasters, to-
gether with the fiue dust from the
dust chamber, is trammed to the top
of the reverberatory building and dis
charged into hoppers directly over
the reverberatory furnaces and
thence by gravity to the furnaces
themselves.
The sample mill is fireproof
throughout, having a steel frame and
reinforced concrete floor and steel
housings for the elevators. The bins
are of steel construction, but the APP
proaches to the receiving bins are all
of timber frame. The rooster build
ing Is all steel with the exception of
the roof, which Is of wood covered
with sheet iron. The Office and shop
buildings are of steel construction.
with concrete floors, but with wooden
partitions with expanded metal lath
on the Office end, so that practically
the entire plant is fireproof with the
exception of the Office partitions and
part of the roof of the rooster build
Ing and sampling mill.
THE reverberatory plant consists
of five furnoces of the Anaconda tpye,
measuring 10 by 102 feet on the
hearth; capacity, 275 ton of calcined
material each per day. The reverb
etories have four waste heat boilers
attached to them, and In addition
thereto three hand fired boilers for
spares. These boilers will furnish
steam to the power plant, which is a
brick and steel structure fitted up
with two triple expansion vertical en-
gines, each directly attached TO 700
%kilowatt, alternating current genera
tors. There are also two horizontal
compound engines. two blowing en-
gines for converter blast and two
ninety-paund eompressors for general
utility. In addition there are the
usuai accomplishments of condensers,
feed water heaters, pumps for feed
water and fire protection, and space
has been left for the installation OF
blast furnace blowers should a blast
furnace be decided on later. The
building is fireproof throughout. and
fitted with an overhead crane electro
cally operated.
The converter building adjoins the
reverberatory building and is a fire.
proof structure of steel with a clay
floor. The converter stands are five
In number, manufactured by the
Power and Mining Machinery COM
pany, and are electrically operated.
There is a compressed air tamping
plant at one end of the converter
building, and a s~ixty-ton crane is In
stalled In the main aisle for the o
ing of heavy mater al, slags, etc. The
matte from the reverberatories will
be tapped directly into the converters

handled. Copper from the ~converters
will be transferred in ladies to the
copper cake molds in the casting
shed adjoining. and at first poured
from the ladies into the molds and
then loaded on cars for shipment.
