SHELTERS At
DOUGLAS ARE
BEING RUSHED
New Stack at c. & A. Is Pro-
ducing Nearly 600 Tons
Daily, and Plans viii Almost
Double Capacity.

The work at the Calumet & Ari.
zcna smelters at Douglas is progress
ing beautifully. The new 500 ton
stack Is wording overtime and is pro-
drcing nearly sixty tons daily. Since
he blowing in OF the large stack the
construction work has consisted prfn-
cipally Of getting together the ma
Jcrials. and the preparations for the
enlargement OF the .smelters.
Il will be Interesting to learn that
before the plans are completed all of
the old furnaces viii be enlarged and
will practically double their present
output
The furnaces. are now 800 tons
capacity, with the exception of the
now one. but trey viii be extended
ten feet. making them twenty-five in
stead Of fifteen feet, increasing the
capacity 200 tons. But the way the
lew furnace has been working it has
been 500 instead of 500. The develop
ing OF the new ore bodies of the c. &
). properties in Bisbee and at Lead
v1llc and other points has forced the
company to make large preparations
icr the treatment of tAe additional
ere.
Superintendent James Wood is Iiur-
ryiRg everything as fast as possible
20 get in shape for the rushing of the
NC-. stacks.
The company has a custom OF
coping one furnace down, so it was
before the sixth furnace was installed
whcn only four of the five were gen.
rally running. and this custom will
continue during the reconstruction
stage, but one furnace being extended
at time. so that the producing capac-
ity Of the plant will not be reduced.
II Is expected to start the first of this
extension work next week and that
II viii take about six weeks TO com
> plote. Then, il all is working we'll,
work will at once be started on the
extending of second furnace which
may be expected to be re-bIown in
about three months from this time.
After that the other furnaces will shut
down, one at a time, and await the
work OF extension till brought TO the
type that has been found most sue,
cessful at Butte.
Today the capacity of the c. G. 4.
smelter has been increased more than
SEQ tons per day over the same time
last, year, and three months from nov
an added capacity of 400 tons per day
may be expected.
At the Copper Queen. .. .-
A matter Of which little has been
heard and still less is general under
stood is the. installation of a new
plant at the Copper Queen smelter
which IS expected TO occur about the
mrs., OF February next. a entering
plant. Experiments along this line
rave been going, on for the past veal
With such good success that the ma
Icrials are now on the ground for a
proposed new plant.
entering Is a process of treating
1ue dust and concentrates so as tC
grepare them for the blast furnaces
ard to avoid loss in the blast. The
fluc dust and concentrates or either
arc mixed with suipIide ore and treat
ed by blow pipe fame till entered o.
somewhat roasted. This process re
moves some Of the sulphur and anal
sPnates together the ore, dust anC
concentrates into a scrt of honey
combed mass which is then readily
susceptible 10 treatment in the bias
furnaces with a minimum of loss. 4
expected that this process will prov,
superior TO the results That are beinl
obtained with the reyerbatory.
The output of the Copper Queer
smelter continues to run at abou
100000 pounds for the month, anC
the output for the year 1908 will b.
nct far from 1O0,6O0,00 pounds OF COZ
