Last week we had the pleasure Of
visiting the works Ofthe Haywood Lead
company at Jose and seeing for our
selves just what is being done by this
company in treating the ore Of the
Cooks Peak district. We found Pre-
sident Ely in charge and the mill run
ming on some low grade lead silver
which Is reduced TO concentrates show
ing 80 Per cent or more Of mineral.
The tailings are practically free from
mineral not showing an average Of 2
per cent.
Starting at the mine we find the
main opening y tunnel a short distance
above the mill and the ore from all
workings Is brought through this tun-
mel in tram cars to the bin above the
mill where the first grade is sorted for
shipment and the second grade dumped
into the bin to pass through the mill
and from the time It leaves the mine is
never touched by hand until the cOncen-
trates are ready to sack for shipment
in the weighing room. To begin at the
engine room we found the power for
the works furnished by four HOrnby
Ackroyd crude oil engines furnishing
in all "a horse power, these engines
Mr.. Ely says he considers the most re-
liable and economical Of any power in
this country where fuel is so high, and
says they require less attention thar
any engine he knows Of, but even here
some trouble has been experienced
from the TACT that water has to be
used to cool the cylinders Of the en-
gines and this having to be hauled al
great expense increases the cost OF
running the engines and in case Of tn,
supply not being sufficient the heating
Of the water In tanks sometimes pre-.
vents continued running of the mill anC
as frequent stopping Is expensive great
ly reduces the profits Of the work
Going from here to the main crushel
we followed the Course Of the or,
through the various processes to th'
finish. Just below the first crusher il
a land dryer, an engeniuos devise o.
Mr.. Ely by which the exhaust from tn,
engines is utilized to dry the ore as i
runs from the first crusher to the sec
ond, from the second crusher It rum
to a set of revolving screens where tn,
stock is graded according to finenes
From these screens the ore goes to
set Of Hooper Pneumatic concentrating
tables, which are 50 arranged as L
separate the ore from the light rocl
by two series Of Slated separators run
ming in different directions, the or
passing out from the lower set ia on
direction while the rock and waste pas
ses through the upper in an oppOsit
direction. The writer has always bee
doubtful Of the practicability Of cor
centration by any dry process but afte
I spending part of two days at this mi
and examining every detail carefully W
: are convinced that the process is a
! ! right and that tic will successfully do tn
: work. In justice TO Mr.. Ely we fe,
compelled to say that few men cOul
Z have taken a proposition like this or
was a practical failure and, againI
many discOuragements worked his wa
: TO q successful issue but with the d.
? termination Of a man who has perfeC
= confidence in the ultimate success (
. his project he stuck to his work an
: corrected one detail after another uni
now he can begin to see his way cle'
and Il Is only question Of little tin
until he will begin to reap the rewal
3 Of his labor.
