THE CLARK REDUCTION
PLANT At BUTTE, MONT.
FACILITY FOR EFFICIENCY
AND ECONOMY.

/ The following description Of the con-
contractor being erected by Senator
Clark at Butte to treat the zinc ores
from the Elm Orlu mine especially
Interesting to the people Of the Occur
dAene district for the reason that Mr.
Clark is developing a great 2inc-lead
producing mine here the Sunset, and
it is not at all improbable that the day
Is not far distant when he viii find
ii necessary to erect great reduction
plant to handle its ores, A depth of
probably 500 feet has been attained
on the Sunset Vein, which it Is under
stood Is merely for the purpose, Of
prospecting 1t az a basis for plans for
It's extensive development This de-
scription of tho Butte mill Is taken
from the Mining and Engineering
World
New Features IN M,lI Construction,
The new mill and concentrating
plant of the Timber Butte Milling
company. overlooking Butte. Mont,
from its prominent position south Of
the city, Is nearing completion. with q
force of 100 men working night and
day to the end that the machinery
may be placed and the mill in rcadi-
ness for opera ton by May /, The mill
will have a capacity of $50 to 400 tons
a day.
Interest has been taken in the mill
by mining and mill men, on account II
the new features introduced in its con-
structon. The fact that 1t is being
erected by the Clark interests and viii
be used, for years at all events, ex-
clusiyely for the reduction of the ore
from the Elm Orlu mine, expla ms the
expensive and painstaking manner in
Which 1t is being constructed. The fea.
ture of the mill from the structural
point of view, is the large amount Of
concrete used. From the head to the
power house the floors, inner walls
and supporting pillars have been con.
structed Of concrete. These have been
built In accordance with plans which
it is believed insure permanently It
was necessary in many places to go
to great depth In securing a solid
foundation. and the foundation walls
are much heavier than the original
specifications called for The great
beams supporting the floors, the floors
themselves and the walls were cast
or laid simultaneously, and are rein
forced with Kahn steel bars through
out.
An Ideal Location,
The location of the mill is ideal, for
two reasons. There will never be ii
lack of dumping ground, and tn.
dumping can be done at a minimum
of time and expense. Then there will
always be an abundance of water Th.
supply is taken from Senator Clark's
Hamilton ranch wells, piped two miles
: ana then raised by pumping 300 feet
The ore from the Elm Orlu will b.
brought by rail and delivered at tn,
bottom of the mill. The mill will b,
operated by both gravity and elevators
The latter taking the ore at the tracks
after it has been passed through two
immense crushers. which Will reduce Il
to u in, Failing upon the conveyore
1t will be carried to the overhead bin
at the head. or top of the mill From
this bin it goes through the large rolls
and after reduction to the Hardirge
mills, and thence to the Wiley anC
James tables, then on to the last pro.
cess, the hotation plant. From here

Ell Is almost identical with that which
; has been satisfactorily in use at the
Butte & Superior for many months
The big rollers have arrived and other
machinery IS on the way. By the
time the equipment Is on the ground
the mill will be ready for its installia-
ton, Work has been expedited by the
early building Of the tram road from
J the tracks to the head Of the mill, be-
fore other work was begun. The tran
road IS 500 feet long and has an aver.
