CHEAP PROCESS
FOR SAYING VALUES

No other one discovery and devel-
opment in Utah mining in the last
ten years will compare in general pub
lie interest with that of the Knight
Christensen Metalhrgical company,
of Provo. according to William III.
Child & Co. While its success has been
a matter of speculation and comment
for the past twelve months, not un-
til the recent official statement of the
remarkable results of the first mill
cleanup did the public begin to rea-
lie the Importance to the mining in
dustry of the new process. A cont
paratively inexpensive mill that can
take So ore and making a recovery of
S5 per cent to 95 per cent of its val
ues turn out precipitates worth $3.50
a ton molds within it's grasp wealth
making possibilities which few men
appreciate. Already a number of pro-
camps have begun negotiations for
mills with the Christensen agents for
which they readily agree to pay fixed
royalties of 10 cents a ton With
such mills dotting not only the big
mining camps of this state, but iitl-
rately extending into Nevala, Idaho,
Montana, Colorado and other states,
Canada and Mexico, the final scope of
the Knight Christensen Neurological
company royalty income mav be IN,
agined. Ores from all these sections
have been successfully tr..~e1.
The mill constructed last winter at
Silver City, Tintic, has Il cap.citv Of
100 tons in twenty-four hours This
process was erected only fo- expert
mental purposes incidental to the
quitting into practical forn of any
new invention. Now the inventor i:
satisfied with the simplifed coo, e a
tion of the various departments, and
a little later this plant will be enlarg-
ed to 500 tons capacity and converted
into a custom MILL This represents
an outlay of possibly 100000. 1t
will treat only the Knight ores. The
great grade deposits of Iron
Blossom, Dragon Consolidated, Colora-
do, Black Jack and Beck Tunnel will
maintain it at capacity for fifteen to
twenty years to come. These alone
should furnish a handsome profit of at
least So per ton.
Treat All Silicious Ores.
Mr.. Christensen says the new pro-
cess will successfully treat any slici-
Gus ores carrying gold, silver, copper
and lead, which do not carry too
heavy percentage Of zinc and lime
stone. All Tintic ores can be handled
profitably. This alone insurcs many
mills at the principal mines, and in
consequence large royalties. The first
remarkable cleanup is more unusual
when the low values in the ores is un-
derstood. They were from the Dragon
and averaged six ounces silver, $1.2C
in gold and $ to rs per cent copper
From such ores there resulted precipi'
tation of $40 to $50 in gold, $4 to 75C
ounces silver and so to 20 per cent
copper.
This process is summarized as fol
lows: The ore is crushed for a three
eight inch mesh; sampled, mixed with
salts, dried, crushed to twenty mesh
passed to the roaster, then to the
teaching plant, where the worthless
tailings are slushed off and rich so

The cost of treatment of ore is about
So a ton. Enormous tests have prov

Gold, so per cent to o. per cent; sill
yer, 80 to 90; copper, IS to 9S, and
lead, so to 90.-Herald-R Republican
