HILLsBoRo, N. M, Oct. 26.-Hear-
ing that the eminent inventor VIM.
Thurmand was contemplating the erec-
ton of q concentrating plant at Ell
Paso, Texas, q HERALD correspondent,
in view of the fact that Mr.. Thurmand
ad lately received letters patent on q
dry concentration, which Is supposed to
revOlutioniZe that class of reduction,
called to get his views on concentra-
tion of ores, which will be read with
great interest by mining men, wher-
ever they may be. He said as follows:
"There has been countless thousands
expended to improve on the jig, which
is about the Oldest and perhaps the
most successful concentrator used. to
date. 1t has been slightly improved
1t was on oblong box, whose bottom
was composed of a coarse or fine sieve,
as the occasion required. Upon the bot
tom was placed bed of crushed gale
ns, too coarse'topass through the sieve.
The material to be concen trased was
placed in the box upon the bed, that
was resting upon the sieve. The above
device was suspended at the end of q
forked spring pole, at the same time
ly deep for the surface of the water to
cover the ore. At the other
end of the spring pole
was q man suspended by his hands,
and on tip toe. When it was desired
that the jig should be operated, all
that the partially suspended man had
to do: was to spring up and do Sn on
his tip toes, which gave the motion to
the jig. 1t required some practice,
and good deal Of skill to give the
proper motion to the jig to-, obtain the
hoa Roarlfn hNH oh oHfa fn,
fine ore, . somewhas slower and longer
motion of the man for coarse ore re-
Quired.''
Mr.. Thurmond then proceeds ed to
illustrate the present power, or steam
Jig, differing from the above tip-toe
manipulation, in that the water is Jig
ged instead of the box, by the means Of
plungers, and the waist is carried off
by water, instead of being scraped off
by hand. Mr.. Thurmoud then launched
forth in q TRADE against slime tables
and endless belts and said they were
not worth the room or floor space on
which they we're placed. Nobody but
stock manipulating concerns used them
and all we'll managed mines AID mills
had jigs.
"There are" said he. scientific
principles that if properly applied in
dry concentration are destined to SUI
percede all wet concentration. AL
though there have been many failures
to date, 1 have invented and patented
q concentration on these principles that
when once known will always be used,
not only for lead and zinc ores, but for
all classes of low grade gold and silver
ores. I am going to New York first,
then in all probability [ will
set up q plant at Ell Paso, where
1 can purchase and superintend the
erection of a trial, or advertising, MILL
After thoroughly experimenting,
simply on adjustments only, at my
trial mill at Ell Paso, 1 will move it to
some low grade dump in Arizona: if
possible the dump of the vulture prop
critics, where every known process has
failed, although the values are there.
I know 1 will succeed; there is no such
thing as failure with my machiue.
Air at sea level has pressure of AT
lbs. per square inch. 1 have that pres
sure to vacuum always at my COM
mand. 1 invite discussion and am
eager and able to cross swords with
any and all scientific men, that have
pendants for dabbling in concentra-
ton. All communicatious should be
addressed to me at Hillsboro, New
Mexico" -,.s.
