doubt the finest in the country. A 200
h. p. compressor, driven by electricity,
furnishes the power. The new engine
is a double drum, built by the Union
Iron Works, and each drum will have
rope speed of 1000 feet per minute.
AT present the old hoist is being used
but as soon as the necessary guides are
secured the second compartment will
be used and the new engine put in com
mission. An order has been placed for
a new boiler of high capacity and when
installed will be used for furnishing
steam should the electricity fail or the
compressor get out of order.
The excavation for the mill has so far
advanced that the mason work will in
all probability be started this week.
There will be two buildings, the crush
ing and the concentrating, 98x137 feet,
and the cyanide plant, 179xl24 feet.
Both buildings will be sheaved with
boards covered with building paper over
which will be corrugated iron. They
will be absolutely wind proof. The
operation of milling is very interesting.
The ore will be delivered from 200 ton
bin to No. gyratory crusher, then to
revolving screen which will deliver
the product to two No. a crushers of
the same type. Here it will be reduced
to about three-fourths and passed on a
belt conveyor, 225 feet long, to the
mill bin. Eight stamp batteries will
crush the ore through IL inch screens.
1t will then be sized in hydraulic cones,
the undersize passing to eight Wiefy
tables. After concentration the tail
ings will be reduced to $50 mesh in a
5x22 inch tube mill. The tailings from
the tube mill then join the overflow
from the classifiers and then the entire
product will be elevated to another
series of classifiers which separate it
into two sizes, fine sand which passes
to l6 Frue Vanners and goes to the
cyanide plant.
! The whole mill product after concen-
tration and regrinding will be settled
and dewatered in three 30 foot stee
settlers from which it will be delivered
to agitators, of which there will be six,
