New Process
for Osceola
LATEST METHOD FOR CYANID.
ING OF GOLD ORES WILL BE
INSTALLED ON PROPERTIES
BELONGING TO II. j. SISTY.

Ben X. Koering. mining engineer
and president Of the Koerning Cyan
ide Process company, has become as
sociated with Hal J. Sisty In the Bos-
ton and Cumberland groups in the
0sceola district. They arrived last
Friday from Salt Lake with the in
tention of installing a small mill on
their holdings in the once noted
placer camp. Experiments with the
Koering process at the Wasatch
Utah Mining company in Little Cot
tonwood canyon has shown a saving
within a trace of all the values In
gold ore that carries from rs cents
TO 81 ton.
Mr.. Sisty states that large ton
mage of gold ore of good value has
been opened up on the miner tract
which he purchased about five
months ago from James II. Marriott
at Osceola.
Uniform results have been obtain
ed from the tests made in Utah by
Mr. Koering The first mill to be
erected in Utah has come up to the
promises made for IL by the in
yestor.
AS result Of the success of the
mill in the Little Cottonwood eoun-
try a mill will be installed at Os-
ceola by Koerng Tests are to be
made on ores extracted In that camp
at the laboratory of the Koering Cy-
aniding Process company at De-
.iroit, Michigan.
The process used by Mr.. Koering is
extremely simple and 1t is almost
certain that some new theories of
cyaniding would be brought out with
a better grade OF ore

ing" said Mr.. Koering yesterday.
We simply use a drum that is lined
with a filter. The solutions are sub
jected to pressure and heat In this
drum and the revolving of 1t gives
the cyanide solutions and gases an
opportunity of getting at every par
tcle of the metal.
"The gases aid greatly in this OPP

the old method of using numerous
teaching tanks. BY our process all

We have not found II SO yet At the
Wasatch- Utah the values were all In

minutes. This would allow forty tons

As the ores In the drum are her.
metically sealed, there Is no loss of
cyanide by volatilization and no loss

a great deal more OF the chemicals
than the open tanks can.
Even -four gold can be saved by
this method. Many flakes OF gold are
covered with surface that does not
allow the cyanide solutions to reach
them The grinding process of the
drum gives a surface on which the
solutions can secure action"
The Koering drum has a gate end
through which the pulp can be with
drawn and the ore and solution put

Sdrum. The solutions are drawn out
Through pipes and are aided by all

funnel shaped box that allows the
