even the small mine owner and the
owner of low grade tailings and ore
dumps, the means of earning substan-
tial profits and at the same time free
him from the chains which bind him to
the operators of custom smelling works.
For two years Mr.. Ellis has been work
ing out his method and he now an
nounces that its practicability has been
demonstrated to certainty and within
a very short time q company which has
been formed for the purpose will have a
testing plant operating on large scale
in this city.
In brief, Mr.. Ellis has invented a
fume arrester which saves absolutely
all the values that ordinarily escape
with the fumes which arise in the re-
duction of ores in regulation furnaces.
In addition, he has devised scheme of
treating crude ores and tailings, aud ex.
tracing from them higher percentage
of value than has ever been attainable
heretofore, and that at fraction Of the
cost, both as regards the erection of
works and the treatment of the ore.
Innumerable devices have been tried
and many of them patented which had
for their object the recovery of the
values which invariably escape from
the furnaces in the fumes and minute
particles that are thrown off with them.
To overcome this difficulty, Mr.. Ellis
attaches to the furnace bis fume ar
rester, which is nothing more than a
pipe or fiue running from the furnace
to connection with another pipe or
f1ue through which is driven volume
of water above the point of intersec-
tion with the fume flue. The suction
of the water in it's descent through
the pipe to a settling tank below draws
with it the fumes and gases from the
furnace and deposits the metals in the
form of slime at the bottom. The
water is drawn off and is used over
and over. thus preventing the loss of
any value which the fumes might con.
tain. This part of Mr.. Ellis invention
may be applied at slight cost to any
form of smelling furnace in which such
losses occur.
Iu order to make a complete process
of his applied ideas, the inventor has
also designed furnace with the idea
of taking almost any character of ore
and sabjecting it to complete treat
ment. In a large outer cylinder are
arranged number of smaller ones that
are designed to slowly revolve Into
one end of these cylinders. which may
be constructed of any desired length
and which will be set at an incline to
allow of the roasting ore to move or
gravitate through them, the ore will be
fed. At the opposite and lower end the
ore, divested of it's metallic contents
to high degree by the subjecton of
enough heat to volatilize the metals.
passes out as tailings, the values hav-
ing been collected by the fume arrester,
as stated.
A single cylinder apparatus has been
in successful operation at Mr.. Ellis
laboratory for some time past and the
results obtained from numerous tests
have been little short of phenomenal.
By his method he is saving absolutely
all of the lead and gold and from so to
981s per cent of the silver contained in
the crude ore or tailings.
The cost Of plant to handle from ten
to twenty tons per day, Mr.. Ellis says,
would be about $500, the cost of larger
works being correspondingly low.
Straight gold, gold and silver. or gold,
silver and lead ores, all respond per-
fectly to the treatment, and for $3.50 to
50 per ton the values can be concen-
trated to such form that, where there is
a combination of the metals, the pro-
duct will only need melting into bull
lion.
Yesterday afternoon. before a large
number of interested men, Mr.. Ellis
conducted demonstration on several
sacks of tailings from the old Dry Valley
property, some ten miles from Phoebe
(Nevada). The assay value of these
tailings was 65 per cent lead, 1917
ounces silver and So in gold per ton.
The result of the test will be known
to-day.
The company just formed is known
as the Ellis Fume Arrester & Ore Re-
duction Company. Henry r. Ellis is
President; E. f. Prudential, Vice
President; w. S. Mccormick, Treasurer;
Colonel E. A. Wall, Secretary, the re-
manning director being Colonel A. O.
Ellis. 1t is capitalized for 100000 in
