%ELECTR0LYTlC WORKS
Addition to be Built That Will Double
Its Capicity-NeWS OF the
Mines.

ITO .nyone who has not visited the T..
E M works lately the improvements be-
;,. made there are a revelation, says the
Great Falls Leader. On every naho' eA-
~cavating building is going on ana III
the interior of the buildings new ma
chinery is being installed and busy WORK
men are engaged in every dlfectloh' hiah-
ing ready for the busiest season lhe
works have ever known.
Of course, the first sight that strlkes
the observer is the large addition TO the
concentration. 1t is nearly hnlshed no"
and some of the jigs are already in place.
In the meantime bricklayers are pussy
! building a firewall between the Old con-
centrator and the new one. me con-
centrator. under the charge of Mr.. Esta-
brooks. is running full force and the ore
as if comes from the bins is taken down
| through the crushers and over he jigs,
slime tables and frue anners until all
| the ore is taken out and held and only
the tailings are left to be swept into the
river, below. Some remarkably rich ore
is now being treated. When the new
concentration is fully completed the ca
! nacity of the concentration will be dOub-
led. -
The increase in the capacity of the
eHl lCJS o1oo W.
crease in the balance CT the works ana
, plans are now ready~for doubling the
electrolytic plant. The work OF nullu-
ing has not yet commenced, but VIII ne
in very short time, SO that the extra
! force now employed at the B. T. M. Will
I be still kept at work, while new men
will have to be employed permanently IN
the concentrator and other departments
E~xcavating has been begun for the
erection of two more blast furnaces ana
A., nrrn NOV. hojnO 1n1f IN.
These two furnace will, of course great
" increase the capacity of the smelling
department md will also require more
men to look after them. In addition,
nine more McDougall roasters Will be
| added to the plant, the old roasters be-
ing abandoned. The use of che McDou-
call roasters is said to effect a saving OF
a, dollar a ton over the old method, the
new process taking fewer men to attend
to it, the roasters working automatically
and a series of ploWs carrying the ore
from floor to floor. The ore is put IN at
the top, the various ploWs on each 1loor
! being inclined toward. the center and to-
ward the sides alternately, Keeping the
! ore moving from floor to floor. The con-
tents of the roaster keep getting hot
ter and hotter as they move toward the
| bottom, until they reach he lower floor
with the sulphur and other foreign prop
critics removed.
In the converter rooms, preparations
are also pGli1S I1O LII AAAA
proyements and an increase in capacity
it having been decided to raise the
roof of the buildings some five feet and
put in four more conVerters. A new
thirty-ton electric crane, larger than
those now in use, will be put in, and is,
in fact, now on the ground.
!, Besides all these other alterations, the
work in the machine shop has become
so great as to necessitate the erection
of a ffty-foot addition to this building
and the work will probably be begun
within a few days.
Among other labor-saving inventions
to be put in by the company in an air
compressor in the boiler shop, for the
use of pneumatic tools. This machine is
on the ground and will probably be put
on place this week. BY it's use, all kinds
of boiler work may be lone much fast
er than by hand, in the old n
A new pump II will also be put in
the work of ~excavating having been fin.
ished and the ground has been cleared
for the erection of a new power house
by the side of the old one, where new
dynamos for the electrolytic works viii
be installed.
