AN ELECTRICAL PROCESS.

AN ELECTRICAL PROCESS.
A New Plan for Working Rebe11ious
Ores to Be Introduced in the West.
| George D. Burton, of New York,
thus describes new process for work
ing rebellious ores, which he intends
to introduce in the West: ''The ore is
placed in receptacle of about half a
bushel capacity, made to stand an esti-
mated heat of 10000 degrees, which is
greater heat than can be measured
by any pyrometer now in use. The
bottom of these receptacles are perfor-
d ted with holes from one-half to one
inch in diameter. Any number OF
these may be used in battery to get
whatever capacity may be required.
AS the ore is heated the metal melts
and drops i'll globules down through a
solution coming up through the hole.
with its gravity increased by adding
salt, soda, borax, alum, cyanide OF
other acids.
Different metals require different
densities, depending on the amount OF
heat required to melt and cause them
to leave the ore. The voltaic ores
could not be formed without increasing
the gravity, neither would the metals
leave the ore without some f1ux to
make it run.
"By increasing the voltage one metal
after another can be removed separate
~. For instance, take piece of ore
containing silver, gold, copper and
lead. With low voltage and moder-
ate amperage and by elevating the So
luton into contact through the holes,
an arc is formed, and lead will be liq-
uitied and go down. Then by increas-
ing the voltage and amperage silver
would fall, and SO with copper and
gold, all fusing at different degrees
of heat.
"The works in Canada are for work
ing the nickel, and there all the nickel
in the ore is saved, while but about
half is by the old process. Aside from
that, by this process and the use OF
condensing stacks, all sulphur, arsenic,
and other volatile and valuable ingre-
dients may be saved. In other words,
erything of value, and all of it, is
separated and preserved. 1t makes no
difference how rebellious the ore may
be-and this means a great deal when
you consider how much valuable ore is
not worked at all on account of the cost
by the old process. AS to the cost,
there is great advantage, and the
electricity may be transmitted twenty
miles to a mine from the source of
power, thus saving the cost of hauling
the ores"
Mining Notes.
At Coos Bay, Oregon, it is claimed,
chemical process has been found that
successfully separates the fine gold par
ticles from the black sand Of that re-
gion. There is lots of this black sand
all along the coast, and if successful
process really has been found for get
ting the gold out of it, many millions
will be added to the Western states.
Mining matters in and around Lew
iston, Montana, are in a prosperous
condition. The Ammon and New Year
properties are in full operation. Sew
eral small sales have taken place dur
ing the past week or two. Claim own
ers are busy doing assessment work
and it is safe to say that not less than
two thousand claims will be repre-
sented in Cone Butte, Moccassian and
Judith Mountain districts this season.
Thirty or forty members of the Brit
ish Columbia board of trade, Victoria,
will shortly pay visit to the mines OF
West Kootenay, they will remain
about two weeks and will no doubt re-
turn and report that the mining claims
worth having are owned and con-
trolled by Americans, who were the
first in the field and made known to
the British Columbias what splendid
mineral country is within the borders
of their province.
The schooner Golden Gate, which
has been on prospecting tour among
tn eislands of the Aieutian Archipelago,
returned to San Francisco with tales OF
wonderful mines, where rich ore is to
be cut out with a cheese knife. The
Golden Gate sailed from San Francisco
on the 26th of May with a party OF
young men, who had agreed to share
expenses and profits of all Alaskan min
ing expedition. Three of the party of
twelve or more returned with the
schooner but they are full of buoyant
hopes, and after the ore brought down
in the hold of the vessel is assayed,
will return to the islands with more
machinery. The men say little about
the location of their big strike, but it
was learned OH board the schooner that
the mine in which they place most re-
lance is on one of the islands just
south of Kodiak island. The ore is re-
bellious but rich enough to warrant the
expenditure necessary to properly mill
it.
