Gently accomplished than the organ
ization of the Nevada Ore Treating
company, which has been inst eff
fected by W. s. Taylor and j. Lemie.
Mr.. Lemie returned from Los An
geles Tuesday where he and Mr..
Taylor had succeeded in interesting
more capital than will be required
Mr.. Taylor also returned accompan-
led by w. S. White, C. E. of Los An
geles. These gentlemen at once bus
led themselves in selecting a site for
the mill, and decided upon a point
a half mile south of Springdale on
the west of the railroad, which is
easy of access, convenient to the rail-
road and where water in abundance
can be obtained and have secured
the property for the company,
At this point it is intended to erect
a mill for the treatment Of custom
ores Immediately. The mill will have
forty tons capacity, and will be
equipped with Professor Wiswells
apparatus and process now owned
and being manufactured by the In
ternational Ore Treating Machinery
company of Los Angeles.
The particular advantage claimed
by this process is the high per cent
of recovery of the precious metals,
end the speed and economy of the
process. Arrangements have been
already made to treat the ores of the
Pioneer lease and 1t is promised that
the treatment charges and the rec0v-
cry will show a great advantage over
the present plan Of shipping. OF
course the size of the plant will
not take care Of all the ore now be-
ing produced by the Pioneer, but the
plant will be added to just as soon as
it gets to running smoothly.
1t is also proposed that another
similar plant will be installed at
Beatty t 0 treat the. ores of that sec
ton, after the first is installed.
The following is a brief description
of the process:
The solving of the problem OF saw
ing fine gold, metallic silver and cop
by amalgamation has been ac%
by Professor F. A. Wis
swen, who has introduced machine
for amalgamation in chemical sol
that promises to revolutionfze
this important branch Of mining. For
years a heavy percentage of values
have been lost through plate ANAL
gamation because of the fineness OF
the metallics leaving the pulverizer,
and because these particles were
coated with either vegetable, alkafl
or other mineral substances that pre-
vented them from being absorbed by
mercury-coated plates.
Under Professor Wiswell's process
it is now possible not only to ANAL
.gamate successfully this fine gold,
but to accomplish it at much less cost
than for cyanide, the cost for chemi-
Gals for each ounce of gold treated
amounting to from 4 to IA cents,
while cyanide treatment costs from
SO cents to a dollar more per ton.
The cost of preparing ore for treat
ment being the same in either pro-
cess: but the chemical amalgamation
process requires only twenty minutes
treatment per ton, as against thirty
six to forty-eight hours by cyanide.
This system Of chemical amalgama-
ton consists of Introducing the pulp
into the chemical solution amalga-
mator as it leaves the pulverizer, az
ter being elevated and watered, re-
curing no extra mechanism for its
introduction. This feed pulp is adj
mitted to the machine with a deter
mined and regulatable amount of
mercuric-chloride in salution. In
this manner particles of gold that are
SO fine as to require from thirty to
thirty-six hours to settle in common
water are Immediately precipatited
and become amalgamated with the
solution, which before dissolving is
70 per ZEN metallic mercury, which
is recovered.
Tests made ON sulphide or other
pres show that the process excels
anything under amalgamation, and
the percentage of value recovered de-
ponds almost wholly upon the per-
centage of vaIues released by pulver-
lection. Tests made on placer gold
which have baffled experts for years
in seeking a process of saving the
fine particles of -four gold, show that
the iWswell process is the only thing
adaptable for this purpose. Under
this system cyanide tanks can be
done away with and the necessary
handling of pulp after the cyanide
solution has done it's work is elimin-
ated. The machine is perpetual and
needs only to be stopped, say once
a day or week requiring less than ten
minutes time to tap off the amalgum
In using the Wiswell process of
chemical amalgamation, it can be APP
piled either to a stamp mill or in
connection with rolls, and the only
requisite is the fineness of the pulp
leaving the pulverizer. In the case
of sulphide ores, or where the gold
is encased in oxidized particles, the
pulp must naturally be fine, resulting
in a greater amount of saving and
economy than is obtained through
plate amalgamation or cyanide. Be-
fore placing his discovery before the
public, Professor Wiswell has made
exhaustive tests, and upon these
tests has been able to readily. fix the
percentage of savings and cost.
With this great step in amalgam-
alton, 1t is only a question of time
when plate amalgamation will give
