"A Mysterious Machine"

A mysterious machine says a Worlds
Fair bulletin built OF FURNISHED steel,
copper and silver. occupying a space
1ix3O feet, and entirely covered with a
glass case, win be the center Of the
state Of Utahs mining exhibit In the

Worlds Fair,
This machine is called the New Con-
contractor" and its mission is to as
semble the valuable metals from the
ores and separate them from the worth

parts. connected with pipes and troughs,
belts and chains One might liken II to
thrcshlng machine. with the glass
case corresponding to the red wood
covering OF the latter, and permitting
the visitor to sse how the various ares
are concentrated.
There Is more than one reason why
the machines IS covered with glass In
the 0fst place. Utah's commissioners
want the Worlds Fair visitor 10 see
how rich their ore ls then they do not
want perspiring hands 10 come In con-
tact with the highly polished machin-
cry, and In addition they DO not want
the visitors 10 nut their hands I'm little
shining piles Of gold. and allow the
precious dust Ia trickle through their
fingers, for gold has a faculty Of stick.

Ing holes In the pockets Of others. The
very sweapings from the floor of the
room where the conceB traitor docs its
work yields many dollars worth Of pure
gold which would be lost were II not
confined.
The ore that supplies the grist for
this wonderful machine will be mined
In Utah ana transported TO the Worlds
Fair grounds, where great ore crushprs
win grind up the huge boulders and
small pebbles. and reduce the mass to
fine sand This process viii take place

from there 10 the Concentrator
Here IL enters a large trough and the
electric power that moves the machine
Is APPLIED. The large trough vibrates
and Tho SAM flows down the incline TO
platform, where II spreads out and Is
Violently shaken Then Il passes on to
another trough, and through It TO an
other platform, where II Is carried up
In buckets 20 higher platforms, and the
Shaking process is repeated. So on
through the big machine, with It's many
cradles.
The heavier metals are thus separated
from the mixture. gold being the first
TO free itself from the mass and the
shining particles pour In a tiny stream
into a receptacle, where they slowly
accumulate. Copper is conveyed to
another level, lead to another and the
sand, with all Of the valuable ores ex-
tracted, Is conveyed TO large bin,
where II Is carted to the dump.
The cyanide method Of extracting
gold from the ore is equally interesting,
ana Utah VIII show this as completely
as the other, but in the outdoor mining
space, however. The ore Is reduced TO
sand IN the crushcr, the same as in
other methods then II Is passed through
n series cf large watts, IN one Of which
Is a solution Of cyanide Of potassium.
When the gold Is touched by this solu-
ton Il Is dissolved Then the water
with the gold held IN solution Is drained
into another trough. the baser metals
remaining with the sand In the vat.
IN The next vat another chemical il

solid form and settles to the bottom
Where Il can be easily collected
To complete yhe task OF extracting the
pure gold the ore passes through II

plain the chemical actions, and give the
reasons therefor Large bars OF pure
