TO SAVE GOLD IN DRY GRAVEL
Boiling Pot Concentrator Is the Most
Recent Invention-May Be

Special to The Herald.
WICHITA, Kas., March 13.-If the de-
vice now being manufactured by the
Boiling Pot Concentrator company of
this city should prove working sue
cess it will add immensely to the an
nual output of gold in the United
States and incidentally enrich the in
ventor and manufacturers. The COM
pany has just completed one of its
machines, designed to extract gold from
placer gravel without the use of water,
and will ship it to Arizona or New
Mexico for a practical test.
Previous to shipping, however, a test
will be made here on shipment of
gravel from the Snake river placers of
Oregon and Idaho, the owners of GER
tain claims out there having heard of
the concentration and requested the
privilege of sending down some "pay
dirt" to try it on.
The Boiling Pot Concentrator COM
pany is local concern, as the company
is controlled and owned mainly in
Wichita. The plant has a capacity of
eight to ten tons an hour of placer
gravel. The concentrator Is a simple
device that by the application of COM
pressed air and agitation produces a
rapid and effective saving of the gold
in dry gravel.
One of the great problems for which
solution his been sought in the gold
bearing sections of the Rocky noun
tains ever since the first discovery Of
the precious metal there is a dry pro-
cess for recovering placer gold. There
are vast fields where it is impossible
to get water for washing the gravel at
all, though it is known to run high in
free gold, and others where 1.-THE sea-
son" is but six weeks to two months
In length, that is, the mountain
streams, dry except when fed from the
melting SHOWS on the ranges, are filled
only until the June flood is past. The
remaining weeks and months of the
year are idle ones for the placer miner,
who is helpless without the aid of
water. For this reason countless at
tempts have been made to invent q
dry process that would do the work
thus far without success. II the new
concentration will extract the gold, the
manufacturers will be kept busy night
and day for long time to come, for the
area of the Rocky mountain placer
fields is practically unlimited.
In the North Park of Colorado alone
there are millions OF dollars i'm gold
waiting to be taken out. The field there
resembles the old river beds of Califor-
MIA, and the deposit of pay dirt is said
to be from sixty-seven to seventy feet
deep. 1t is full of gold varying in
coarseness from flour" gold to mug
gets worth as high as 500. The extent
of this field is perhaps fifty miles north
and south by seventy-five miles east
and west, 1t is the source OF the North
Platte river and is traversed by in
Vulnerable tributaries, the sands of
each and every stream being 'lousy'
with gold Nearly all of the field has
been filed on and worked in a desultory
and the dream of the miners
has been the eventual discovery OF a
dry process" that will enable them to
take out the treasure that they know Is
there but are unable to recover.
The result of the testing of the new
will be watched for with
intense interest i'm every placer camp
from Colorado to the Pacific coast.
