COPPER AND THE
BAGHOUSE PLAN 7
System in California Shown to
Be the Success That Was
Anticipated.
WAS THE PIONEER
IN COPPER WORKS
Engineers of United States
Company Paved the Way
Without Precedent.

One OF the most gratifying improve
nents in recent smelling is The success
fu operation OF the playhouse system oi
arrcsting the Injurious materials Whleh
heretofore had been cast out upon the
outer air 10 the damage OF surrounding
farm lfc The system is especially
gratifying 10 the state of Utah. FOR the
lead playhouse installed and put INTO op-
Grafton at MidValc by the United states
Smelling. Refining & Mining company has
permitted this company 10 resume opera
lions i'm its smcltcr with tho sanction OF
the courts.
The next step taken by this company
was the trial of q playhouse system ior
the copper smelter In California. ana an
idea of the success OF this plant is given
in the annual report OF the company ana
In that portion of the report prepared by
Frederick Lyon, vice president OF the
company in charge OF company operation
Mr. Lyon says;
Mining company the extraction of the
ore amounted 10 33O.635 tons. Develop,
ment work was prosecuted vigorously and
the tonnage of ore developed is fully
equal 10 the tonnage extracted. so that
the reserves at the first Of the year were
maintained. An entirely new lens oil
ore was struck toward the end OF the
wear AS far as explored il proves - be
Of much larger extent than any found
since the opening up OF the nam ore
body, The work Of exploring TINS lens
be a, least as high as the average OF
the main ore body.
Baghouse Operations.
The playhouse. to which reference was
made in last years report, was finished
and pu; in operation on July b. IL was
z success from the very beginning and
removed all the deleterious substances
from the fumes Just as the playhouse is
doing al Midvae The success is the
more gratifying as this playhouse is the
first erected In connection with copper
plant.
There being no precedent to guide the
engineering department in such problems
as hltering area and cooling surface, II
was considered wise to he conservative
In the construction so as to avoid an un-
necessary high expenditure of capital. As
q result 1t was found on completion that
the playhouse was not able TO take care
Of the fumes OF four furnaces, but did
care successfully for the fumes of two
furnaces.
Capacity Decreased.
In order to comply fully with the de-
cree of the court which permits the COM
panv to operate. and In order 10 live I'D
IN The spirit OF the understanding with
the farmers IL was considered wise TO
operate tho smelter at one half capacity.
In tie OF the Increase In the treatment
costs per ton OF ore and the material re-
ductiun Of profits which were the neces-
sary result Experiments were at once
started with View OF finding means to
increase the capacity. and before the end
of the wear these experiments were so
successful that A third furnace was
started without any addition 10 the bag
house. By the installation of an auxiliary
fan the company will be enabled to op-
crat" three furnaces steadily and sue
cnssfullv. The experiments will be con-
''nrcd with view 10 further improve
mcnts."
