THE ELLIS PROCESS.

improved Method Of Treating Ores
Which Saves High Percentage.
An experimental test Of the fume ar
roster invented by Henry B. Ellis, was
made in Salt Lake City and proved an
entire success. A description of this
new process, which it is expected will
revolutionize smelling, vas given in
late issue Of the se...:. Lake Herald, as
follows:
In brief Mr. Ellis has invented
fume arrester which saves absolutely
all the values that ordinarily escape
with the fumes that arise in the re-
duction of ores in regulation furnaces.
In addition he has devised scheme
Of treating crude ores and tailings,
and extracting from them higher per
centage of value than has ever been
attainable heretofore and that at a
fraction Of the cost, both as regards
the erection of works and the treat
ment of the ore. Innumerable devises
have been tried and many of them pat
ented which had for their object the
recovery Of the values which invaria-
bly, escapes 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 ar
roster, which is nothing more than a
pipe or fiue through which is driven
volume of water above the point Of
intersection with the fume flue. Tae
suction of the water i'll its descent
through the pipe to a settling tank be-
low draws with it the fumes and gases
from the furnace and deposits the me
tails in the form of slime at the bot
tom The water is drawn off and is
used over and over, thus preventing
the loss of any value which the fume
might contain. This part Of Mr.. Ellis
invention may be applied at slight
cost to any form of smelling furnace
in which such losses occur.
In order o make a complete process
of his applied ideas, the inventor has
also designed a furnace with the idea
Of taking most any character of ore
and subjecting it to complete treat
ment. In large outer cylinder are ar
ranged a 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 the roasting ore to move Or
gravitate through them. the ore will
be fed At the opposite and lower end
the ore, Invested of it's metallic con.
tents to higher degree by the suo-
lection of enough heat tovolatilize the
metals, passes out as tailings, the val
ues having been collected by the fume
arrester. as stated.
A single sylinder apparatus mas
been in successful operation at Mr.
Ellis labratory for some time past and
the results obtained from numerous
tests have been little short of phenom
email. BY his method he is saving abso
lutely all of the lead and gold ana
from so to I9S3k per cent OF the silver
contained in the crude ore or tailings
The cost Of the plant to handle from
ten to twenty tons per day Mr.. ELL
says, would be about $500, the cos
of larger works being corresponding!
low. Straight gold, gold and silver, o
gold silver and lead ores, all respoE
perfectly to the treatment, and TO
$3.50 to $500 per ton the values ca
be concentrated to such form tina
where there is a combination of tn
metals, the product will only need me
ing into bullion.
