.YAEGER CANYON
CONCENTRATING
Plant Will Soon Be in
Operation.
An Elaborate But Thorough SyS-
TEN Devised for Working the
Ore Successfully.

The starting of the Yaeger Canyon
mill has been delayed for some weeks
on account of the screens or rather
on account of the absence of the
screens, which have not yet arrived.
This plant is to be strictly con-
centrating proposition and to the I'M
itiated, is at first sight rather COM
plicated affair. Once following the
ore through the different divisions
and subdivisions, and that which at
first seemed very intricate becomes
simplicity itself.
The process consists of a systemi-
sing and then concentrating. 1t is
we'll known fact that concentrating
table will work to better advantage
on material which is all of the same,
or very nearly the same size, and the
concentrating at the Yaeger mill Is
based upon this principle. The sizing
is done by "Elliott screen sizers' and
the concentrating by Bartlett, Card y
Wiley concentrating tables and Will
fey sluicers.
In detail the process of sizing and
separation is as follows:
The ore from the mine is dumped
on to a grizzly, the undersize going
direct to storage bin and the over
size through No. Austin crusher
and thence to some storage bin. From
the bin the ore goes to a Challenge
feeder, and thence to sizer No. l. This
siZer consists of two screens, the top
six mesh and the bottom a twelve
mesh. The oversize from the six mesh
goes to the coarse rolls. The undersize
from the six mesh and the oversize
from the twelve mesh go to the coarse
elevator, and together with the pro-
duct from the coarse rolls go 70 the
floor above and to sizer No. ,. This
sizer No. also consists of a six mesh
and twelve mesh screen. The over
size from the six mesh goes back to
the coarse rolls and i rerun until it
passes the six mesh screen. The IN
dersize from the six and the oversize
from the twelve goes to the Bartlett
table. All of the undersize from the
twelve mesh goes to the coarse Wiley.
The tailings from the Bartlett and the
tailings from the coarse Whitley go to
the fine rolls and together with the
wider size from sizer No. l are ele-
waited to the upper floor where they
go to sizer No. 3, which consists of a
single screen of twenty mesh. The
oversize from this twenty mesh screen
goes back to the Fl ne rolls and is re-
run until it passes. The undeIsize
from sizer No. 3 represents the total
product of the mill, with the excep-
I tion of what has been removed by the
| Bartlett and coarse Wiley tables.
This product then goes to sizer No. 4,
which consists of thirty mesh and a
! fifty mesh screens. The oversize from
the thirty mesh goes to a card table
and the tailings from the card, out of
the mill. The undersize from the
thirty and the oversize from the fifty
mesh goes to a Wiley and the tail
ings thence out of the mill. The IN
dersize from the fifty mesh goes to a
| Whitley and the tailings from this Will
| fey go to two Wiley sinners and
thence out of the mill.
There are fifteen separations going
on all the time beside that of the con.
centrating tables. By beginning the
concentration on coarse material and
recrushing the tailiDgs and continued
accommodating the greatest possible
extraction will be obtained.
J. B. TomIinson is manager of the
property and has worked out the above
scheme to its successful application.
The plant is being erected by Ell
lott d Drescher, the Elliott screen
sizer forming an important factor
in its mechanism.
