LOCAL REDUCTION PLANT
IS A GREAT SUCCESS

Discovery and extraction Of ore by
no means complete the chain connecting
the purchase Of mining stocks with the
receipt of dividends. Two Of the most
important links are reduction and trans
portation- latter may be obviated
and the former accomplished by the
Nevada-Goldfeld Reduction works. a
local concern that has done much. very
much. to earn for Goldaeld the merited
title. The Greatest Gold Camp on
Earth"
To relate the story of the founding
and growth of the Nevada-Goldfeld Re-
duction company would be a twice told
tale and a lengthy one. A few para
graphs as TO the modus operandi of the
plant would doubtless prove more enter
tanning and Instructive.
The company receives ore by cars as
well as by wagons. The railroad cars
are run in on an upper track and thence
pass by gravity through the establish
ment. The cars pass over a railroad
scale fitted with an automatic register
beam on which the car and ore are
weighed. The amount Of a~voirdupois is
punched on duplicate tickets by an au-
tomato mechanism and the owner Of the
ore receives one, the ompany the other.
Thence the ore passes to the unloading
bins and passes to the receivers and
on to the crushers. Meanwhile the
unloaded are weighed and the duplicate
tickets are again punched. giving seller
and purchaser the opportunity to find
out by q simple operation in substrac-
tion the actual weight of the ore.
After being unloaded and rolled out of
the building by a gravity system. the
cars are reload with the sampled ore.
This waiting track Is on the opposite
side of the building and another set Of
scales registers the weight of the ore
before 1t enters the cars. the duplicate
check being given to the owner of the
ore for comparison with the minuend Of
the two previous weights.
To revert to the received ore. II Is
taken to the big crusher, which has a
capacity Of I'VE hundred tons per day.
The ore here IL broken to about one
half mesh. Then It is caught by a verti-
cal elevator and raised ninety-three feet
to the first station. at which one-tenth
is cut put and dropped to the first set
of big rolls, where 1t is crushed to
nearly o~ne-fourth mesh. This one-tenth
is raised to the second vein and one
tenth of this, ore o~ne-hundredth of the
whole, is cut out. This second sample
drops through the second set of rolls
into the sampling room proper. 1t is
Their fed by hand through a third set
of rolls. and after thoroughly mixing
1t Is coned and quartered to several
hundred pounds. This smaller sample
is then passed through the coffee grind
ing mill. then rolled. coned and quart
cred and finally pulverized through the
disc mill. 1t Is again quartered to the
assay sample. Four samples are made.
The owner is llowed the privilege of
taking two, the third Is marked "Um-
pire" and put away in case of any dis
pute, the fourth being used by this COM
pany for their assay All this work Is
done in the presence of the owner. The
whole Of the ore after passing through
the vezin flows to its separate storage
bin in which 1t is held until the owner
satisfied with the result. the settlement
is effected.
The building contains twenty-four of
these large storage bins on the shipping
side, each having a capacity of seventy
tons. These bins have hopper bottoms.
and are so arranged that the ore will
flow from them to the shipping out
cars on the lower track.
on the opposite side from the ship
ping bins a similar lot Of bins used for
handling the mill ore. The works are
connected by numerous spurs and rail-
road tracks. the arrangement of which
allows the handling of a whole train
of ore, once the same has been pushed
in by the railroad locomotive.
From the mill bins the ore flows to
the elevator which transfers 1t to the
mill building proper, where there is a
SOO-ton storage bin over the battery.
From the mill storage bin the ore passes
to a special feeder. by which 1t is fed
to the batteries. The batteries are the
latest and heaviest bossed type, 1850
