A NEW
Working FIue Dust.

Last February Mr.. L. Goliath, ,
Salt Lake mining operator, and owner
OF large smelling works some six mile.
from Salt Lake City, came to Eureks
and bargained with the Eureka Con
solidated Company for the purchase o.
the immense accumulation of fue dust
at the Consolidated reduction works
A sale was effected at the rate of So pc,
ton, and it was calculated that the
amount to be delivered would reach
10000 tons. 1t was known that the
fue dust was very valuable, samples
of it assaying from $40 to $50 per ton
in gold and silver and carrying a large
percentage If lead and iron. A great
many OK periments have been made at
the different furnaces to find some
method Of working the the article so
as 10 leavea margin Of profit, but with
very little success, and the dust carried
of by voiatilization and caught in the
cOndensing fiue has at most OF the fur
naces been allowed to accumulate or
the dump pile. The Richmond Com.
pany was an exception to this rule,
that company having reworked it in
the form Of slime. but experienced
sInelters have been of the opinion that
nothing MAS gained by this method,
the added moisture and increased fuel
more than counterbalancing any profit
derived from the second working. Be
this as it may, the sale to Messrs. Col
bath IL Co. was consummated, and MIR.
Clark, ~ of the Salt Lake firm, hav-
inty YotynfIufQH Snnotol rofoS with tin
railroad companies = $I3 per ton
freight from Eureka to Salt Lake
commenced shipping the article. The
Utah ores lack iron necessary for
smelling and iuxing and it was cal
'culated that as the dust carried 20 per
cent. of that metal, it would in a great
measure dispense with the necessity If
buying iron ore and leave the precious
metals as a profit on the speculation.
.In this way vas the fact accounted
for, that Salt Lake smelters could
ship the dust from Eureka and work
il at a profit. Mr.. Clark shipped 500
tons, when the forwarding was inter.
ruped :or a period. This was in con-
sequence OF certain discoveries having
been made in regard to methods Of
working it, a discovery that dispensed
with smelling entirely, and intro.
duced an old and very simple process.
Mr.. Goliath, in conjunction with n
OF the best experts in the Territory,
Mr.. Wallace, tried u number of exper-
iments Is to the best method of reduce
ton. Finally, the idea occurred to
them that the pan process, the same
as used in an ordinary quartz mill,
might solve the problem. Five tons
of the dust were shipped forty miles
to a distant mill, anu we understand
that it was treated the same as the
pulp from underneath the stamps.
We will not be positive on this point,
as the discoveries are very reticent,
but the dust was run through the
pans and the result was that the
working process gave a return
Of within 81 43 Of the fire as
say. AS soon es this ex.
pertinent proved successful Mr..
Clark proceeded to San Francisco and
opened negotiations with George C.
Clark, wholesale paper dealer in that
city, and principal Stakeholder in the
Lemon Mill, of Eureka, for the lease
of the mill property. The negotia-
tons have been pending for a month
past, during which time we have been
in possession of the facts, but under a
pledge of secrecy. A. ID. Haskell, a
stakeholder in the mill, and author
ICED agent of the Lemon Company,
has leased it to Messrs. Clark Il Wal
lace, who will at once renovale aud
put the mill in order. We understand
that they will not only work the dust
by their process, but also any tree ores
that may be found in this vicinity.
The importance OF the enterprise to
Eureka can hardly he exaggerated.
The loss by volatilization is estimated
at IL per cent. on every ton of ore that
goes into the furnace, and if this pro-
cess of working that wastage is q suc
cess, it adds that much to the value of
the ore extracted, less the differ
ence between tbs turns and the fire
assay, a very small one, as shown
We hope the gentlemen will
meet with the reward due their energy
and shrewdness.
