The Butte inter mountain. [volume] (Butte, Mont.) 1901-1912, 1901-12-21

They are constructed for the most part
of steel, brick and stone; wood, how
ever, has been used extensively, but all
Of the buildings are considered to be
practically proof against destruction by
fire.
In the construction Of these man,
month buildings $500 cubic yards Of
masonry forms the foundations of the
various buildings and stacks. The
brick used for building purposes num-
Der 1850, 900, of which 100000 are
common red building brick and the bal
ance, 100000, are fire brick.
The stone used in the foundations
was brought here from various parts Of
the state where building stone is
quarried. Structural steel has BEEN
used to the amount of about $4,000 tons.
also 20, 500, 900, board meausre, of lumber
In the concentration bins, concentrates
bins and concentration 100000 feet OF
lumber has been placed.
The tonnage of materials of all
classes used in the building of the
works is something enormous. Includ-
ing the structural parts, machinery,
stone, brick, etc, there was used APP
proximately $4,000 carloads, averaging
20 tons each, or 24O, 900 tons. If all these
cars had been coupled together they
would have made up a single train OF
the length of "A miles. e
In dimensions the concentration buildJ
ing is the larger of the group This
structure is $40 feet long and continues
in six tiers or sections down the hill
for a distance of 600 feet. Below this
still are three sections of slum bins,
which extend across the entire length
of the building for GAO feet. In the con-
centrator building proper there has been
used 4,175,0O0 pounds of structural steel.
Additional to the concentration are built
some immense storage bins for ore and
COAL -.,f.
These bins are $40 feet long, "a feet
wide and 80 feet high, which required
in their construction 1892, 900 pounds
of structural material.
Since these bins We're installed it was
decided to build a trestle of the length
of 28S feet on each end of the bins; they
are now completed. They were con-
structed of steel and are so arranged
that should necessity ever require it,
they, too. could be converted into ore
bins. In these trestles no less than
100000 pounds of structural steel was
used. making a grand total of nearly
100000 pounds Of structural steel in
the concentration building, ore bins and
trestles-apprOximate a little over
5000 tons.
The next building in size is the re-
verbatory. 1t is put up in two sections,
which in reality are separate buildings
Each section bears the dimensions of
175x250 feet which required the use of
1920, 900 pounds of steel.
Then comes the rooster building, 375
feet long and 100 feet wide, which cons
tains 4S of the latest pattern MacDougall
furnaces. The structural material in
this building weighed before being set
up 2.23O,OO pounds. 1t will be interest,"
ing to note also that the shells for the
rooster furnaces set up in this building
have a weight of 100000 pounds and
the castings and shaftings as much
again, making a total weight of struct-
ural steel, castings and furnace shells
of S.230,000 pounds, or Ais tons.
The converter building is 174x462 feet
in dimensions. In it 2,215,OOO pounds of
structural steel was employed.
The blast furnace. S2x2SO feet, cannot
be overlooked. In 1t $4,000 pounds of
structural steel was required.
