In the teaching department there are
ten teaching tanks, each 25x5OX12 feet
in size, with a combined capacity of
holding 1900 tons of ore, besides which
there are three solution tanks 20 feet
in diameter and u feet high, and two
stump tanks, of the same size, besides
three precipitation tanks, which are IA
feet in diameter and feet in height.
Nearly every mining man in. Utah is
familiar with the rnodus roperandi in
the utilization of the cyanide process
of ore reduction, and that to be en-
ployed in the operation of the Golden
Gate mill will not materially differ
from the usual methods, excepting in
the treatment of the oxidized ores of
the mine, the handling of which Cap
tain De Lamar. assisted by an efficient
and brainy corps of assistants, has
evolved
A SYSTEM OF HIS OWN,
which, it has been demonstrated by re-
peated tests, is eminently successful on
this character of ore.
In the treatment of the oXidized ores,
the mineral will be hoisted from the
mine to the top of the mill, where it
will go through the crushers, through
the rolls and over the screens to the
crushed ore bins from which place it
will find its way to the teaching tanks,
the gold in solution passing on to the
precipitation tanks, from where, in the
course of time, the cyanides, or pro-
duct, in whatever form it may assume,
will appear at the sampling room,
where the bullion-buyer makes settle
ment with the company for its metallic
contents.
With the arsenical ores it is different,
the mineral going from the crushers
and rolls into the pulp bin, which has
holding capacity of 5000 tons. From
there it is run into the dryers and from
these receptacles into the roasters.
where the arsenic is expelled by heat,
assisted by a secret process worked out
by superintendent lacking, after
which the prepared pulp is subjected to
the teaching solution and the final re-
covery of its gold contents follows.
At the start it is not the intention
to treat more than 500 tons of ore
daily, but as soon as the work is weli
in hand this output will be increased
to 500 tons per day, with the likelihood
that IN the near future at least LOCO
tons will be the amount of ore that the
plant Will take care of every "a hours.
AS is well known, the motive power
for the mill and mine is obtained by
the application of the electric fluid. to
receive and apply which the property
is equipped with II dynamos of an ag-
gregate capacity of GOO horsepower,
and these will furnish sufficient power
for the operation of the mill, the opera
ton of the hoist and the manipulation
of the machine drills.
Of course. the working of both mine
and mill on such gigantic scale neces-
states the employment of
A SMALL ARMY OF MEN,
and it is understood that at the present
time the company has the names of
300 employees on its payroll, which
means the distribution of a small for
tune every pay day, which in itself,
means much for the prosperity of the
camp of Mercur and also, indirectly,
for the state at large.
In this direction, ii is no more THAI
just and right to compliment Mr.. II. A
Cohen, Captain De Lamar's right-hand
man and first lieutenant, for the part
he has taken in bringing order out of
chaos, in building a splendid structure
on a spot which a few years ago was
nothing more than a Wilderness Mr.
Cohen has worked early and late in
achieving such splendid results, and
in his labors he has been ably assisted
by a corps of the best talent to be
found in this country, every man of
which is entitled to words of praise
and complimentary mention.
The photograph from which the
above pen sketch of the mill was drawn
was taken yesterday. especially for
The Herald by c. E. Baker, Mercur's
skillful photographer.
1t is not the intention of the writer
to make an extended mention of the
mines at Mercur owned and operated
by Captain De Lamar. as it is well
known that in their underground
workings magnificent bodies of ore are
blocked out and exposed, sufficient in
