of tins city, is tie inventor n pro
cess which promises to reyolntiouizt
present smelling methods and place
within the reach of even the small
mine owner and the owner of low
grade tailings and ore dumps, the
means of earning substantial 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
working out his method aud he now
announces that its practicability has
been demonstrated to certainty and
within very short time a company
which has been formed for the pur
pose will have testing plant oper-
ating ou 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
reduction of ores in regulation
furnances. In addition, he has de-
vised scheme of treating crude
ores and tailings, and extracting
from them a 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. Innumerahle devices have been
tried and many of them patented
which had for their object the re-
covery OF the values which invari-
ably 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 his
fume arrester, which is nothing
more than a pipe or fue running
from the furnace to connection
with another pipe or hue
through which is driven a
volume of water above the point of
interrogation with the fume hue. The
suction of the water in its descent
through the pipe to settling tank
below draws with it the fumes and
gases from the furnace and deposits
the metals in the form of slime at
the the bottom. The water is drawn
off and is used over and over, thus
preventing the loss of any value
which the fumes might contain.
This part of Mr.. Ellis invention may
bs applied at slight cost to any form
of smelling furnace with the idea OF
taking almost any character OF ore
and subjecting it to complete treat
ment. In large outer cylinders,
are arranged number of smaller
ones that are designed to slowly re-
volve. Into one end of these cylind-
ers, which may be constructed OF
any desired length and which will
be set at an incline to allow OF the
roasting ore to more or gravitate
through them, the ore will be fed.
At the opposite and lower end the
ore, divested of its metallic contents
to high degree by the subsection
of enough heat to volatilize the
metals, passes out as tailings,
the values having 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
aud the results obtained from num-
erous tests have been little short OF
phenomenal. By his method he Is
saving absolutely all of the lead and
gold and from 80 to 981 per cent OF
the silver contained in the crude ore
or tailings.
The cost of a plant to handle from
ten to twenty tons per day, Mr.. Ellis
saws. would be about 81 500, the cost
of larger works being correspond
inely low. Straight gold, gold and
silver, or gold, silver and lead ores,
all respond perfectly to the treat
ment, and for $1.50 to 50 per ton
the values can be concentrated to
such form that, where there is a
combination of the metals, the pro-
duct will only need melting into
bullion.
Yesterday afternoon, before
large number of interested men, Mr
Ellis conducted demonstration on
several sacks Of tailings from tne
old Dry Valley property, some ten
miles from Pioche. The assay
value of these tailings was 6.3 per
cent lead, 1O.7 ounces silver ana 20
in gold per ton. The result OF the
tes, will he known to-day.
