Mine Ready to Supply Tonnage.

Il nave only been operating one steam
shovel up to the present time in supply
ing ore to the new MILL said Mines Man.
ager Gates during the afternoon, but an
other shovel or two and about 80 ad-
ditional men will be put to work right
away. Everything is ready at the mines
to supply Mr.. Bellies plant with all the
ore it can chew up and it would not
bother me much to keep the mine end up
If the tonnage demanded was double the
capacity of the mill as its starts off. The
task of limbering up the machinery, try
ing out the crushers, cOnveyors and the
hundred and one thing incident to the
starting of such a large plant, has been
going on for several days. and l under

Mr. Gates stated also that the new no.
tel at the mine which has been construct
ed to replace the one destroyed by fire
early in the winter has been finished and
is now ready for occupancy 1t will ac-
cOmmodate $50 men and that number is
as many as the company expects to have
to care for as large proportion of the
force is composed of men who have their
own homes and private places at which
to live. Within another week the COM
pany will be employing d larger force of
men than at any time in its history and
it will be only a matter of short time
till the Boston Consolidated company will
be turning out copper in as great guam
tity as the Utah Copper company. even
though the mill of the latter company is
of twice the capacity of the Boston Con-
solidated plant. This will be the case
because the latter company will ship
enough sulphide ore direct to the smelter
to make up for its lack. of milling ca
Dacity. And ii may be said In passing
that there IS absolutely no question but
what the Boston Consolidated mill will
be enlarged during the present year; that
is a foregone conclusion.
Mill and Its Equipment.
Now that the mill is about ready to
begin its career of usefulness. it will be
interesting to know something of the
plants characteristics and the methods
that are to be employed in recovering
the copper from the ore, The mill build
ings are constructed entirely of steel.
The crude ore is received in a main bin
over which the railroad trains travel and
which has capacity of $1,000 tons. From
this main bin the ore is taken by con-
veyOr belts to the crushing plant, which
is equipped with four Gates rotary crush
ers. From the crushing plant the ore is
taken by slightly inclined conveyOrs to the
top of the main mill bins which have a
capacity equal to that of the receiving
bins. There it is distributed by a trip
per belt the entire length of the bins.
Crushing of the ore in the mill is &C
complished by 312 Nissen individual
stamps. arranged in double rows lOngi-
/ tuGin&lly with the bin. These stamps are
fed automatically and crush to 2S-mesh
Pulp is passed to the ciassifiers, where
/ it separates into three divisions passing
thence to the various machines for the
recovery of the product. which include 2S-
Whitley tables. 255 Johnston tables and
312 CallOw settling tanks. Settling ca
pacity of the plant is unusually large AL
! the clean water from the settling tanks
passes to a stump. which sends it bach
to the main supply.
A distinguishing feature of the Boston
Consolidated cOmpany's mill is that there
is not an elevator in the entire plant
Everything passes by gravitatiOn through
the works. The daily capacity will run
from 5000 to 200 tons.
The company has no investment in DOW
er plant. as it has secured a very ia
vOrabie rate from the Telluride Power
company for electric power which is re-
ceived at $1,000 volts at its transformer
| house.
The water supply is obtained partially
| from springs son the company's mill site
but principally from the Garfield Water
company. which corporation is owned
| Jointly by the American Smelling G. Re
filming company, the Utah Copper com.
! Dany and the Boston Consolidated Min
| ing company. and which has secured con
troll of and arranged for the delivery OF
some 1900 gallons of water per minute
| from various sources of supply within
a distance of twelve miles, at the plants
of these three corporations.
