The Hope mill will be started up in ;
short time, running on Sweet Home ore
and as Mr.. Patten has in sight an enor

Combination Mining and Milling Co
A visit to the Combination company'l
plant at Black Pine last Saturday re
vealea the exceptionally prosperous
| workings by that company. The histor,
Of this camp dates back only about three
years ago, when the Black Pine Mining
and Milling company was organized an6
| proceeded to develop the property
| Under that management a tunnel was
| run in about $50 feet, without making
| much OF success in reaching the ore
body that was then supposed to exist
| and which has since been exposed he
yond all anticipation. The Black Pine
company was in existence less than q
year when their funds became exhausted
! and the stock being non -assessable they
| were obliged to discontinue. A reorgani.
| zatioa soon followed and the property
| has since been managed under the pres
ent head. with results most t1attering
| The company is at present employing
| sixty five miners. twenty mill men. forty
wood choppers and number of men en-.
gagged in miscellaneous occupations
This camp is located twelve miles due
; west Of Phillpsburg in dense forest OF
q io IT,,
good for carrying on such an enterprise
are enormous and each discovery made
seems richer than the one proceeding it.
Following We give :; detailed description
OF the mine and mill; also the manner in
which they are being worked:
THE MINE.
The vein may be properly termed a
segregated vein; it's course is northwest
and southeast, and its dip (Which is
about 20 degrees) conforms to the strait
fication of the sandstone. The vein, al
though faulted, as are all of this type, is
continuous in depth, well-defined and
quite uniform in thickness and value.
The vein matter is quartz, mixed with
the chlorides, sulphides and antimoniates
OF silver and the carbonates of copper
and lead.
The method OF laying out the work re-
qulres close attention. The usual
method OF attack 10 as follows: Levels
are driven on the strike of the vein;
from these drifts are run at right angles
to the levels and 1G0 feet apart. In
these drifts chutes are put so feet apart
and raised up to the vein. The ore as
stopped is hauled in barrows and dumped
into the chutes. At the bottom of these
the ore is conveyed in buckets, of about
8OO pounds capacity, placed on trucks,
to the shaft; thence hoisted to the sur
face. From there the contents is dumped
into capacious bin, from tile bottom of
which the ore is transferred into wagons
and hauled to the mill, distance Of 4
miles,
is a wet crushing and of the ordinary de-
sign, having 10 stamps of 500 pounds
each, with drop of ~ inches and 80
per minute; each stamp crushes about
215 tons in "a hours. The process is
different from the one usually practiced,
viz: concentration before analgamation.
The ore as it comes from the mine is
dropped over grizzly; that which passes
through is fed into the battery by self
feeders; that which goes over is crushed
in Blake crusher and goes thence to
the feeders.
After being stamped IN the battery the
wet pulp passes through a 4O-mesh
screen; thence elevated and goes through
a partial sizing operation. From there
it is distributed On four Frue vanners;
the tails are allowed to settle in vats and
to the pans. The concentrates
are. removed to the drying floor; from
there they are fed into a Brueckner
roasting furnace, and with an ademix- |
Eure Of salt and pyrites are chlorodized, !
cooled and transferred to pans
The pans are fed with about 1900 |
pounds of pulp, 100 pounds quicksilver,
70 pounds salt, iron filings and about 2 !
pounds of sulphuric acid The pulp is
zept at about $50 deg F, and the revolv-
ng mullers making Is revolutions per
minute. After about eight hours
| sufficient time has elapsed in which the
ilver minerals have been decomposed
md the metallic silver combined with
he quicksilver; the contents of two pans
re discharged into one settler and kept
Il constant agitation, the agitators max
ng IA revolutions per nainute. The
malgam is now tapped from the settlers,
trained of the excess of quicksilver,
eaving the amalgam five quick to one of
liver. The amalgam is retorted, the re-
ort metal melted in plumbago crucibles,
nd cast into moulds, and the silver is
eady for market. The tails which flow
rom the settlers runs to waste. Going
ack to the settling tanks tho water and
me shines (Which are nearly 215 times
8 rich as the original ere) is pumped by
China pump into a tank which feeds
he battery by a two-inch pipe. This ar
keeps the fine shines in con-
tant circulation and there is practically
o loss from that source.
The future of the Combination prom
'es we'll. Al! that can be done towards
1creasing the saving by matchmaking
r Russell process will be done. Much
redit is due the economical management
nd painstaking manner in which the
xperiments are conducted to obtain the
cry best practical results. w. A. Akers,
ae manager, in combining his profess
pnal talents, coupled with thorough
ability, is Of vast service to his
ompany, and the Combination mining
ompany may we'll feel pleased with him
= accrcing profits through his labors
nd those of his efficient foremen,
