placed at the mouth Of Gold Run. The
concentrator catches from quarter TO &
half ton OF Homestake concentrates pei
day. We have been informed that be
has already stacked for treatment at the
new cyanide plant oyer 100 tons of con
centrates which 90 $12 per ton gold
The estimated cost of their treatment ID
s6 per ton. Several more Of the con
centrators will be placed at advantageous
places in the creek channel between
Puma and Lead.-Times.
The Omaha smelter has been entirely
shut down for several days in Its smelt-
ing part and the refining part has been
running one-fourth capacity. The sup
ply Of ore TO start up with has been
secured, and last night three stacks were
blown in. Later three more will be
started. The ref merry has been run
with material sent from western smelt-
ers, and the roasting department with
the supply on hand before closing the
furnaces. sixty men are taken back on
the furnaces started and many more in
other departments.-Wo Herald.
Professor Uhlenberg, assayer for the
Homestake Mining company, returned
to Lead yesterday from Denver, whith-
er he went to test the adaptibiiity Of THE
bromine process in the treatment OF
concentrates from the Homestake mills
From source which we are not at liberty
to make public, we understand that the
test was quite successful We under
stand that upon the success Of this test
run depends the erection of a small
plant at Lead using Professor Engle-
hardt's process. BY the way this pro-
cess is meeting the approval Of many of
the leading mining men Of Colorado,
and its adoption in many Of the mining
districts in that state is one Of the pos
sibilities Of the very near future. There
is fortune in it for the members Of the
company handling it, one of whom is
DR.. J. A. Paddock Of this city. We con
gratulate the doctor on the lead pipe
cinch he has on a fortune.-Pioneer, l6.
NEW coScENTRAroR.
Iier Bros. this week made a test run
with their new concentration on a small
lot of ore from the Sambo, says the Rico
Sun. The product was turned into
three grades Of concentrates, the tailings
showing the concentration could save a
larger per cent Of the ore than any in
vention yet patented. This concentrator
is entirely new inven ion, although il
was patented by the Her Bros in Ohio
over two years ago. One Of the princi-
pal features ofthe invention is implicitly
Of construction and economy in operat-
ing In fact the entire outfit complete
would cost but little more than the price
Of one Frue vanner. Another is that
the machine is especially adapted TO
reducing the huge bodies Of low grade
silver and lead ores which predominant
throughout this district and which will
never be made profitable without con.
centration. The initial plant is capable
of treating from eight to ten tons daily.

CYANIDE is INDEED KING.
The cyanide process as handled by
the Gold Recovery Company, of which
j. S. Childs and DR.. Taylor are the
heads, has been proven beyond per-
adventure to be great success. Yester
days cleanup resulted in a bright
yellow brick weighing 95 ounces, valued
at 81 800. This brick was the produc,
of So tons of ore from the company
property at Blacktail. The ore averaged
SIS per ton. This shows an extraction
of a trifie oyer 80 per cent. 1t is one oi
the most satisfactory clean-ups ever
made a. this plant. The clean-ups
made prio. to the rejectment of the
Morrell pulverizer showed as high as 81
per cent by extraction. But now since
the plant has been fitted with finishing
rolls in place of the puiverizer, the
crushing of the ore has been gotten
down to a science and the percentage oi
extraction has been increased and the
working of the plant greatly facilitated
In cyanide the problem of treating the
low grade ores Of the Hills has beer
found. Not that the process is cheaper
than any other-we think it is, thougl
but in that it saves higher percentage
Of the metal contained in the ores. II
chlorlnation we understand the cost o
reduction per ton is S2.77 with an ex
traction Of IS per cent. Pyritic smelling
costs per ton $500, and as high as 5!
per ton extraction 7s per cent. Free
milling ore reduction by stamp mills, s.
cents per ton, when handled in quantl
ties such as the Homestake handles j,
saving in extraction from IS to IS pc
cent average saving 6S per cent; cyn
nide, cost of production per ton So, pc
cent of extraction 80. The success O
the cyanide process shows its adaptibil
ity TO the ores of this section. The ore
which have been treated at this plan
can be termed representative ores G
this district, or at least the district GOV
cred by the blanket or fiat formation
which are Of refractory and very re
bellious nature, and heretofore onl
susceptible to the chlorination an,
smelling processes. The operations Q
the cyanide plant since its resumption
have not been experimental runs-th
days of experience being long passed b.
but runs made with understanding
that The process was n success and doinl
the work for which 1t was intended, a
demonstrated by the experimental run
of long ago.-Pioneer, Is.
