NEVADA CONSOLIDATED Is RUSH.
ING WORK IN ALL LINES AND
MAKING MANY ADDITIONS AND
IMPROVEMENTS TO PLANT.

With eight sections in operation
at the concentrator, with prospects
of plenty of water for the coming
season, and unlimited ore in sight,
all departments of the Nevada Con-
solidated's big plant present scenes
that point to record produc-
tion of copper during the next year.
Not only are the present facilities be-
ing utilized to good advantage. but
numerous alterations and improve
ments are being made that are ex-
pected to still further assist in swell
ing the company's output. At the
big pit at Copper Flat, the water
utilized by the Nevada Con. the
latter company having arranged to
pump the water for its use from the
Ely Con. workings during the tenn
porary cessation of operations at that
mine. At the Liberty pit, steam
shoyels are in operation. one in ore
and the other on overburden. Here
tofore the ore has been taken from
the Eureka pit, but from the present
outlook, the production from the
Liberty pit will largely exceed any
thing ever credited to the Eureka.
At the mill, the rifles on the Will
fey tables are being changed. for the
purpose of securing a heavier ton
mage without reducing the extrac-
tion. Good results have been obtain
ed from the changes already made,
and all the Wilfieys will be equipped
with the new rifles. A test is also
being made of the Isbell Universal
concentrator. on coarse tailings. The
question of how to secure the best
results from the treatment of tailings
Is an ever present one, an dthe new
tables will be given a very thorough
trying out to prove their adaptability
to earn their own living by working
on tailings which have been discard
ed by the mill. The Isbel concentra-
tor is designed TO treat much coars-
er material than is worked by the
Craven sinners.
The water capacity and the slime
settlement capacity at the mill is be-
ing increased by the installation of
16 Dorr continuous thickener tanks.
while other tanks of the same type
Will be put in at the east end of the
concentrator. where grading for their
installation is being done Of the
latter there are to be eight. each
eight feet In diameter and 20 feet in
depth.
At the smelter end of the MeGill
plant important alterations have
been made to the roasters, by using
forced air draught Thus far the re-
suits show an increase of so per
cent per day in the capacity of the
roasters. BY a slight modification
being made on the reverberatories,
converter Stag will be taken from the
ten-ton side dump ladies'. These al
terations Will take the cold Stag skull
formed in the ladle, without the
necessity of breaking up. Hereto
fore the cold Stag skulls have been
returned to the concentrating depart
ment. broken up with the crane
weight and sent to the crushers be-
fore going to the reyerbs.
This hot converter Stag is being
handled by an oil-fred locomotive re-
Gently purchased. 1t will be interest
ine to see the development in the use
of California locomotive oil in loco
motives at the plant, as against the
cheaper Utah fuel. The California oil,
although more costly as locomotive
fuel, has Its distinct advantages,
among them being absence of smoke
and cinders.
