miles from Salt Lake City The smeiter
Is connected by its own railroad (the
Tooele Valley railway with the San Pc
dro. Los Angeles & Salt Lake railroad.
the junction being about seven miles from
the smelter site. The smelter Is located
TO large extent for the level OF delivery
OF the product of one building 10 be the
level OF the charge floor OF the next sue
ceedinE one,
The Ores-The ore treated comes prn-
cipally from the mines OF the Utah Con-
soldated Mining company in Bingham
Canyon. These mines In Bingham Can
yon are connected with the smelter by
an aerial tramway. four miles long. hav-
Ing capacity OF I25 tons per hour Gus
tom ores from other mines are received
Tooele Valley railroad
Receiving Bins-The receiving bins are
e,onstructed Of steel and are fireproof
capacity OF 10000 tons OF ore and coal.
The bins are so located and arranged tina t
they may be served either by the fifty
ton electric larry cars. which deliver the
standard railroad cars.
Sampling and Crushing.
Sampling Mill and Crushing Plant
This building Is OF steel and concrete |
throughout II Is !oxS4 feet IN plan, and
is hye stories high The, mill is COM
posed OF TWO sections. and each section |
has a crushing and sampling department |
The ore from the receiving bins is con-
.y Xeyed by belt conyeyors; which feed
ers. The ore from the crushers is ele- |
waited 10 the top OF the building by bucket |
elevators. In the sampling department
the ore is cut four times by Brunton
automatic samplers. cutting out one
NTH OF the amount each time and dis
carding four -ffths. so that of each ton
OF ore crushed a sample weighing 80
pounds is obtained.
The sampling department OF each Sec
tion OF the mill contains. besides I2x24
inch Blake crusher. which is common to
the crushing and sampllng department:
One GA Brunton sampler
One 90xl0-inch crusher,
One Ia sampler.
One 4Sxl2-inch roll
One "a sampler.
One 26x15-inch roll
One "A sampler.
The discard from the sampling ma
chimes drops into screens OF the crush
veyed to roaster bins The final sample
is quartercd by a quarIering shovel the
resulting sample is then dried on steam
dryer. ground in al Englehardr sample
grinder. and again ground In Braun
pulverizcr. so as 10 pass through 100
mesh sieve. The 100-mesh product is
OF which goes TO the snelter laboratory
for analysis. one to the owner of the ore
and one IL filed away for use in case of
a dispute.
The crushing department Of each sec
tion Of the mill contains:
One 12x24-inch Blake crusher
Two As inches by IA feet screens,
Two l5x9inches crushers,
Two 4Sx12~inches rolls
From the crushing plant the crushed
and sampled ore is conveyed by belt ccn-
veyors 10 the McDougail roaster steel re-
ceiving bins which have a capacity of
500 tons. II II is desired. the coarse ore
after being sampled may be conveyed to
the blast furnace steel receiving bins,
which have capacity OF $500 tons A
blast furnace has not yet been installed.
