The Modern smelter, at Utah juno
ton, few miles north of Denver,
receives considerable ore from this
section for treatment
Again Colorado leads the states in
gold production. Ninety-five million
was the output for the entire coun-
try. OF this, Colorado's record is in
the neighborhood of twenty-three mil
lions.
About twenty-five wagons are haul
ing ore in this section. At three tons
each and several loads day makes
a pretty large output by horse con-
veyance. This is insignificant com
pared with the amount handled by
the Gilpin county tram.
The expression is often used that
desired than small, rich pay-streak.
The small, rich pay-streak has its
limitations. it Is true, but the small
and rich vein may lead to another
and eventually to a large ore body.
1t Is not well to despise the small but
good things handed out.
What is wanted more than anything
in mining Or In &c,
system whereby ores may be concen-
trated at the mine. A car loaded in
the mine, comes to the surface in a
cage, from the surface it is rallied
to crusher or pulverizer and from
there dumped in a receptacle which
washes away all the dirt, saving only
that which has a specific gravity
greater than water. Such an idea has
been worked out but not yet proven
by test or experiment.
One Of the big deals of the year
was the consolidation Of interests
OF the Kansas and Burroughs proper
ties. group on Quartz hill, which
were decided to ]. E. Lightbourn and
j. c. Jenkins. as trustees. These
properties will be reopened by
syndicate of capitalists. Having been
idle for number of years this new
acquisition to the mining industry
will mean a great deal to this Sec
ton. Work Is expected to begin with
in a very short time
A cheap method for handling ores
from the mine is always an interest
ing subject to mining men. A system
seen In the Black Hills dead City,
South Dakota), worked like this: A
car was filled with ore in the breast
OF the tunnel. drawn out to the shaft,
placed In the cage, hoisted to the sur.
face and upon reaching the surface
ran on a tram to the mill, automatic
ally dumping the ore into bin which
automatically fed the stamps, neces-
stating one handling OF the ore.
II 1t were undertaken, and 1t Is not
impossible Of success, many dumps Of
old-time mines as well as new could
furnish thousands Of tons of ore of
an average of five dollars per ton.
Ore OF that value II concentrated
ought to return a good income where
the capital invested is not too
large basis. II all the values in this
kind Of ore were saved and utilized
1t would pay handsomely. Were the
gold and silver. the copper. lead, zinc
and even the pyrites all saved by
some process or other every mine
dump would become a very good
proposition. indeed. What a fearful
waste OF good values.
Electrolytic methods for refining
gold are gradually superseding other
methods. The elecro-chemical treat.
ment Of ores is also receiving con-
siderable attention. A process where.
by gold In solution could be caught
on copper or iron plates, like elect
roplating would prove very interest
Ding process were 1t worked out Crush
ing the ore very fine. dumping 1t into
the proper solution and then connect
ing the electric wires with the plates
and these immersed In the solution.
giving the plates movement through
the solution and ore, should prove a
very cheap method for extracting
gold and copper from the ores con-
taining such metals. f
