new PROCESS FOR
SAVING VALUES

1t has ever ben the dream of the
prospeetor and miner that he might
live to see a process discovered
through which for a small amount of
money he might build him a little mill
at his isolated holdings; reduce his
values to metallic form or a high
grade INT and ship TO market
with the least possible expense and
tie greatest possible profit to him,
the legitimate human manufacturing
factor in the creation of this new
wealth for the world. That happy
day has come; the process perfected
and a little fve-ton plant is right now
demonstrating il every day at the
Salt Lake Engineering works. Fourth
South and Sixth West. according to
C. W. Clapp and his associate, Col
George F.. Cooke. who have con
strueted, equipped and perfected the
Clapp process. II takes the crude ore
and by roasting and using certain
cheap chemicals turns off the waste
and precipitates and the metals
separated and in metallic form, or in
a high class concentrate. This is the
first story the world has had of this

long and toilsome series of evolvings,
requiring the application of twenty
FIVE wears of the lives of two men.
Mr.. Clapp has spent the past even
years at it. In his tests of yesterday,
for instance. he put a certain kind of
nickel ore through an analytical pro-
sess thirteen times. Each time the
chemicals were varied to secure a pos
sible better The two cru
cibles with the best results were
marked .'good" and their record IS
preserved.
New Discovery.
ssThis is absolutely a new diseov-
erv in metallurgy,' said Mr.. Clapp-
"Never before was the chemist able
to take iron. lead and copper ores;
mix them, grind them up and extract
each metal separate" Last year W.
s. Butler, chief copper .metaliurglst
OF the United States bureau of mines,
was here and investigated. he ex-
pressed establishment in witnessing
Mr.. Clapp make one of these demon
stations, and in just twenty ve
minutes.
s'There are billions of tons of ore
in Utah which with this process ean
be made profitable continued the
matallurgist. "Take for instance
the immense tonnages of the oxldlzed
Gaping which is being removed and
dumped as waste every day at Bing-
ham. This ore probably carries to
Is per cent copper. The mills are
handling only the sulphides. Our
process can treat oxidized Gaping
rock successfully.
"Then there are the nickel de
posts of Nevada, Oregon, North Da-
kota and North Carolina. This car
ries from 4 to 6 per cent. We expect
TO have our process working in all
these districts. Where the United
States in 1912 imported all but 34s
tons of the 10000 tons of nickel used,
we expect to be supplying that 80
900 tons from home mines in less than
five years.
High Recoveries.
"The mill we have here will
handle in a day one one-half tons OF
nickel ores, four tons of copper, three
tons of iron, silver and gold and I'VE
toms of lead ores. We claim to be
able TO make extraction ~reeovcries as
follows: Copper ores. 90 to 9e.6 per
cent; nickel, 99.6 per cent; silver,
gold and anthony, pure; iron and
lead, 96.7 to 99.6 per cent.
"Our mill can be made any size,
from ten IONS up to thousands of tons
daily. A 100-ton plant will cost about
$25. 900. 1t can be worked either by
the dry or wet separating process. 80
il can be successfully operated IN sec
t;ons far from water. 1t will use for
fuel either wood, coal, gas or oil.
Colonel Cooke said yesterday: I'VE
consider that we have worked out a
process that will revolutionize mining
in the western states. Few local peo-
pie seem interested, but they will
probably wake up when il is too
