In treating the fumes from the cop
per furnaces the same methods VIII
be used as for the lead silver furnaces.
The only difference will be the use OF
additional hues to cool the gases and
keep them from destroying the bags.
The United States company Is the
only one of its size In the world that
has successfully conquered the smclter
smoke question 1t Is continually i'm
proving the method. The company
offers better inducements to its ems
ployes to study out new methods than
any other company in the country. If
some new process Is devised by an
employe. the company promotes 1t for
him. and IL it Is then agreeable they
both share in the profits, otherwise 1t
is turned back to the employe.
PROTECTED BY PATENTS.
The company has protected all of its
inventions by patents and the methods
involved have been the most success
full thus far brought out by any COM
pany. Not only Is the method patent
ed In this country. but patents have
also been secured in Canada and
abroad.
The lead furnaces of the United States
company have been treating in tho
neighborhood of 500 tons of ore a day,
or n charge of from 9T5 tons to 1000
tons day. The lead ores treated have
been about equally divided between
custom work and the comrany's own
mines. Tho greatest amount OF lead
silver ore comes from the Jordan and
Galena mines OF the company in Bling
ham canyon and the Centennial-E Eureka
mine at 'rintic Most of the custom
ores come from Tintic.
Although the United States company
| has been quito successful III the use
| Of the HUFF clectrostatic separator for
| treating zinc ores, 1t has greatly added
| to the efficiency of this plant during
| tho year and increased the capacity
without charging the plant, Although
| Bingham ores are about the hardest
| that can be fonud to treat. the United
| States has been well satisfied with re-
suits.
IMPROVE SEPARATOR.
One OF the big improvements made
| by the company was the adding to the
! efficiency of the process. The conccn-
| trates in progress to the separating ma
chine pass through eight rolls, one
: above the other. a device has been
installed so that the finished product
| from each roll Is taken away and the
other sent on for further crushing.
In the separator mill the iron zinc
! concentrates from a wet concentrating
| mill are dried and then separated into
! an iron product, carrying most of the
! precious metals In the concentrate and
! leaving a high grade zinc blcnde prod
| uct for shipment to the zinc smelters.
! This plant alone Is becoming good
source of revenue to the company,
! During the year the United States
has increased It's mining operations in
Bingham canyon. The compressor and
| machinery ut the old Jordan mine was
thoroughly overhauled and repaired and
the force employed was Increased. At
the Centennial Eureka mine ut Tintic
the Holden tunnel was completed. This
| cuts Oft 500 feet OF the shaft and It is
said will mean saving OF $4,000 q
year to the company. Besides that
the company put in n large pumping
plant that will allow q thorough OK
ploration Of the sulphlde zone which
the company Is Just reaching.
BUYS RAILROAD.
Heavy floods early this spring cut off
the railroad from Palisade to Eureka
in Nevada, thus depriv!ng the company
of It's oNidizcd lead-ron ores from
the Richmond Eureka mine at Eureka.
Nevada. The road was recently sold
at shcriffs sale and bought in By
George w. Heintz, general manager of
the United States company In Utah,
This road will probably be repaired and
put In service again.
AMERICAN PLANTS.
No changes have been made at the
| Murray plant of the American Smclt-
ing 4 Refining company during the
| year This plant continued to treat
| its usual tonnage of load silvcr-gold
oles received principally from Park
| City and Nevada points.
| Work was started late this year to
! enlarge the equipment at the Garfield
plant of the company so rs to care for
the enlarged production from the mills
OF the Utah Copper company. ACldi-
| tlonal McDoueal roastors are to be put
In as well rs rcverbcratory furnaces.
! The plant has been so arranged that the
| increasing of the capacity can easily
be done. This plant was constructed
| with great deal of foresight As
soon as the American company scented
| trouble in the Salt Lake valley over
smeltcr fumes, 1t quickly sought on,
a site that would insure it against any
