NINE INSPECTOR BELL

returned from short visit to Salt
Lake, where he attended the annual
meeting Of the American Institute of
Mining Engineers Of which he Is
member. and reports a well attended
&nd instructive sessions, says the
Boise Statesman
Inspector Bell says there were 300
delegates in attendance from all parts
Of the United States, and the Utah
delegation. aggregating upwards to
100 members, royalty entertained the
visiting delegates.
Meet at Hotel Utah.
Technical sessions were held every
evening at the Hotel Utah, and num-
erous papers were presented and dis
cussed at these sessions. bearing on
hydro mechanical, electrical and
chemical treatment of the metal bear
ing ores and the cheapening of pro-
cesses with a view Of extracting the
values from low grade rock containing
gold. silver, lead copper and zinc. or
a combination Of all these metals.
Some splendid examples of pro-
gress were shown along these lines
which indicate that in the near future
processes will be perfected that will
greatly reduce present high smelling
costs and increase the metal extrac-
ton, with the result of expanding OF
at least maintaining the present min
ing industry indefinitely by the utili-
zation of ore bodies that have hither-
to been considered too base or low
grade for profitable treatment.
See Some Big Mines.
The local committees provided spe-
cial trains on four different days for
the visiting delegates, who were shown
among other things through the Sill
yer King Coalition mine at Park City,
at which point unique feature of the
entertainment was the serving Of
splendid luncheon in the new concrete
Timed electric hoist station Of this COM
pany, 1000 feet vertically underground.
to about $50 guests.
On this same trip visit was made
to the old Ontario mill, now being OPP
Grated by Holt & Dern, where new
chloridizing roast and teaching pro-
cess Is being successfully employed,
that shows handsome margin OF
profit in handling the old stope fills Of
the Ontario mine, containing an av-
erage value of IS per ton in silver
with little gold lead and copper, all
Of which is successfully recovered to a
high per cent of extraction by this
simple process.
On another day special train took
the delegation to the big smelter at
Midvale, and also to the large copper
and lead smelling plant Of the Inter-
national company at Tooele, where the
present methods Of ore treatment and
the points Of progress were fully ex-
planned.
Greatest Copper Property.
The most interesting trip Of the ses-
sion was the opportunity afforded by
the famous Utah Copper company to
inspect their great mine at Bingham
canyon, which, other than iron, Is the
largest metal mining operation in the
world, and practically the full at
tendance Of delegates availed them
selves of the opportunity afforded by
this company where the details OF the
operation and the magnitude Of the
deposit were fully explained by the
general manager on the ground.
This enterprise is magnificent
! tribute to the genius Of d. c. Jackling
and his able associates, as 1t has set
pace in the mining and milling Of low
grade copper sulphide ore values that
has been extensively followed and
opens up some fascinating possible
ties in a business way to Idaho, where
we have a number Of enormous low
grade copper bearing deposits that, 1t
is believed, are destined to ultimately
interest large amounts Of capital and
develop large Industrial advantages to
this state.
IT'S Measured by the Mile.
The Utah Copper deposits consist OF
mass of siliciOus gray porphyry I'M
pregnated with an average value Of
about IL per cent copper 1t is
mile and half long by half mile
wide and lays across the main Bing-
ham canyon about 20 miles west OF
Salt Lake, the bulk Of 1t being on the
south slope Of the steep canyon side,
where 1t is being operated by series
Of terraces or open benches, % In
number, to an elevation Of 1900 feet
above the canyon bottom. The ore is
blasted down to the benches and load
ed on the railroad cars with steam
shovels.
