THE AUBURN MILL, RENO.

This mill has Of late assumed a posi-
ton Of leading Importance in the mat
ter of ore reduction in this State, owing
considerably to the eligibility Of its
location, and principally to new and
improved processes adopted, giving
greater and important facilities in the
reduction Of rich and refractory 'ores.
Much Of the richest class Of ores found
in the principal mines Of the Comstock
Is sacked up and sent to the Auburn
mill for reduction, and from many Of
the mines contiguous to the line Of the
railroad, in the eastern part Of the
State ores are brought to this mill for
treatment. 1t was built several. years
@ and was originally intended to
work ore from a lead near by, but that
not proving profitable the mill lay
idle until within the past two years,
when 1t has been made available as
above described, and nov proves to be
good property. 1t Is located about q
mile and a halfnorth from the railroad
depot at Reno, and n large ditch, three
miles In length, conducts a good sup
ply Of water from Truckee river to an
oyershot wheel 81 feet in diameter by
Is feet breast, which drives all the ma
chincry. 4 correspondent Of the San
Francisco Scientific Press, who has re-
Gently visited the mill, gives the fol-
lowing, descriptive Of lit:
The Auburn mill 10 Situated on the side OF a
hill which gives sufficient fall for one set OF ma
ehinery to discharge into the other. rock
cru.her discharges the ore upon plates (warned
BY waste heat nom the farnaee) where Il 10
mixed with a proper quantity Of salt and dried.
It is then fed into q battery OF twenty stamps
and crushed dry. The dust Is conducted from
below the screens by an endless chain apparatus
to elevators that discharge II into a perforated
plate on the top Of a stack or chimney 20 feet
HIGH BY 5 feet square at the ~bottom-thc shaft
OF n Stefeldt furnace, which has been fully de-
scribed In the Press Of December IL, 1863. The
heated air from the furnace passes under the
plate. below the rock breaker, thence through
an inclined dust chamber, Ave feet square,, up
the hill perhaps IS feet. and terminates In q
chimney whose top Is 2S feet above the top or
the furnace shaft. The chloridized ore 10 anal.
gated in - Wheeler pans, whose sides are lined
with x.ieh wooden slaves. to prevent the iron
nom being eaton up by the pulp; the muller Is
not let down heavy on the dies, IL not being ne
cessary to grind after roasting. The pans dis
charge into elk separators. The company have
rooms fitted up In the most complete manner
for rctorting. assaying. etc. They design con-
structing q side track from the Central Pacific
Railroad in a short time, which will enable them
to run the cars into the mill. Nr. Brown, the
superintendent OF the works, claims that this
furnace saves four per cent. OF salt, and that the
amount OF work that required 80 men and IL
cords Of wood by the old process, Ia done BY
this with 8 men and ~ cords OF wood.
L have met quite q number OF miners and
mill men, who speak very fayorably OF the re-
sults nom ores worked At this establishment
among others, Mr.. r. ID. Stewart, Supertntend-
ent OF one Of the silver mines Of Cnionvtne,
Humboldt county, Nevada. Several tell me that
they have previously shipped their high grade
ore, to San Frareisco. but Of late they have had
considerable worked at Reno. and have obtained
decidedly better results: and hence have deter.
mined TO have all their high grade rock worked
there.
