Tonopah daily bonanza. [volume] (Tonopah, Nev.) 1906-1929, 1912-01-18

Namara mill, which mas been IN
course of construction since the lat
ter half Of last year, will have
commenced on the reduction of ore
and started on long and success
full run.
The mill was practically complet
ed a week ago. since which time a
number of experimental runs have
been made in order that necessary
adjustments could be perfected and
the numerous bearings given
chance to wear even. Tests have
also been made of the new skip,
belt conveyors, elevators and rock
erushers. with the result that every
thing is now working as smoothly
as a clock, and from present ap-
rearances there seems to be no rea-
son why for many months to come
there should be any cessation of
operation except for cleaning-up
purposes.
The new MacNamara plant. as
has been heretofore stated in the
Bonanza. consists of ten-stamp
mill Of Williams & Chalmers de-
sign. Dorr elasslfier a 70-ton
per day capacity tube mill, and all
the other tanks. yats. agitators and
paraphernalIa that so to make up
a nrst-class and up-to-date stamp
age and cyaniding treatment; the
kind that has been so essential and
been found so successful in the
manipulation of Tonopah ores. And
with the experimentation OF all the
other Tonopah mills to guide them,
the management of the MacNamara,
in conceiving and constructing its
plant, has overlooked nothing that
would make for greater percent
age of saving.
In the construction of the plant
there has been vast expenditure oi
money probably close to 100000
but the results that will obtain
will surely Justify the spending oi
that sum. Only the best OF materia
and machinery has been utilized ant
nothing has been slighted that woult
serve TO cut down the expense o
power and tend to the automati
working of the whole plant Ever
piece of machinery in the plant |
run by separate motor. in ever
tank and vat there are three o
four passages for the flow of water
in order that unnecessary lifting
may be done away with, and a bi
saving In the way of power bills ha
been secured. And. best of al
human energy is economized an
given greater play by the allowanC
of plenty of room in which II
men about the mill can work.
