UTAH'S UNIQUE DISPLAY.
n Mysterious Machine, Showing How
Gold Is Extracted From Ores, viii
Form an Interesting Exhibit at the
Worlds Fair, 1904

A mysterious machine, built Of burn
ished steel. copper and silver, occupy
ing space l4x30 feet, and entirely
covered with glass case. will be the
center OF the State Of Utah's mining ex-
hibit in the Palace OF Mines and Metal
lurgy at the Worlds Fair.
This machine is called the "New Con
centrator," aud Its mission Ia to assem-.
BILE the valuable metals from the ores
and separate them from the worthless
sand.
The concentrator is remarkable in
vertion, and unless The visitor is
familiar with gold mines and mining
machinery, he would never guess its
use. 1t is complex, aud is built Of
many parts, connected with pipes aud
troughs, belts and chains. One might
liken it to threshlng machine. with
the glass case corresponding to the red
wood covering OF the latter, and per-
hitting the visitor to see Low the var
ious ores are concentrated
There is more than one reason why
the machine is covered with glass. In
the first place, Utah's commissioners
want the Worlds Fair visitor to see
how rich their ore is; then they do not
want perspiring hands to come in con-
tact with the highly polished machin-
cry, and in addition they do not want
the visitors to put their hands in little
shining piles OF gold. and allow the
precious dust to trickle through their
fingers, for gold has faculty Of stick
ing to some peoples fingers and burn
ing holes 10 the pockets OF others. The
very sweepings from the floor OF tue |
room where the concsntrator does its !
work yields many dollars worth of pure
gold, which would be lost were il not
confined
The ore that supplies the grist for
this wonderful machine will be mined |
IN Utah and transported to the Worlds
Fair grounds, where great ore crushers
will grind up the huge boulders and
small pebbles, and reduce the MACS TO
line SAID. This process will take place
in the twelve acre outdoor mining ex-
hibit space adjoining the Palace OF
Mines and Metallursy, aud the sand
will be conveyed from there to the con-
,entratOr.
Here 1t enters large trough, and the
electric power that moves the machine
s applied. The large trough vibrates
Ind the sand flows down the Feline to
platform, where 1t spreads out and is
'iolenlly shaken. Then It passes on to
mother trough, aud through 1t to an
'ther platform, where IL Ia carried up
n buckets TO higher platforms, and the
baking process is repeated. So on
Trough the big machine. with it's
nany cradles.
The heavier metals are thus parated {
-om the mixture, gold being the FIRST 10
zee itself from the mass, aud the shin
ig particles pour in tinyl stream into
receptacle, where they slowly accum-
late. Copper Is conveyed to aoother
vel, lead TO another, and the sand [
i'h all OF the valuable ores extracted. r
conveyed To a large bin, where il lie
lrted to the dump. :
The cyanide method ofextracting gold

tab will show this as completely as
o other, out in the outdoor mining
ace, however. The ere is reduced to
