AIR SCARCITY IN
INSPIRATION MINE
HAS BEEN RELIEVED
Work on the Big Plant at
Miami Is Progressing
Rapidly.


Miami, Ariz., July For some time
past the mine department Of the IN
SEPARATION Consolidated Copper company
has been compelled to work under
handicap because or inadequate ar
supply. but now with the new com
pressor and hoist plant erected and
one Of the compressor units installed
and in operation IL is possible to sup
ply a quantity greatly in excess OF the
requirements. The present instala-
hon. however. is only temporary so
far as the scheme OF handling is con-
cerned, as it viii require several
months TO complete the entire install
alton with its elaborate distributing
system. With the 5000 feet furnished
by this unit, the total available capac-
ity is now about 1900 cubic feet per
minute ample for all development
work requiring compressed air
TresfIe Nearly Finished.
II the present rate Of erection is con-
tinued. the concentration trestle should
be completed in 10 days About %
tons per day IS being put in place and
rivetinS is being carried along with the
erection. Painting viii start soon me
carpenters have nearly completed their
work on the shop extension The com
PAM. carpenters have started laying Of
the composition roofing material on
the main concentration building, and as
soon as the shop extension is com
pleted the entire finishing force OF
~
put to work to complete the enclosing
of the main building. Considerable
rfvetinE. however, remains TO be done
on the concentration bins, but this
probably viii be left until the trestle
IS disposed Of. A large shipment of
steel shelving for the concentration
warehouse has arrived, and work Of
assembling same will begin in a few
days.
Excavation Completed
Excavation for the concentration
transformer station and distributing
station mas been completed and the
forming OF walls. floors and piers has
been started. The latest addition TO
the test mill is five Metals Recovery
company pneumatic flOtation machines
and auxiliary equipment, which are TO
be given a thorough test TO compare
their efficiency with Minerals Separa-
ton process. Although the two pro-
cesses depend upon the same basic
principle, the means Of acquiring the
final result are very different and the
purpose of the company is to deter
mine which is best adapted TO recoT-
cry Of its ores As soon as the neces-
sary parts are received from the east,
q series OF experiments are TO be
crushers TO determine the best steel for
roll and die use. The rolls and dies,
which gave good results on dry brit
tie feed, were found to wear excess
ores, but with a change to one or
combination OF the modern alloy steels
II is believed much better results viii
be obtainabIe.
Because Of a shortage Of steel, cree
tion Of the engine house unit Of the
power plant at the smelter site has
been necessarily slow. but the building
is now erected and the riveGng should
be finished in q few days. The eL-
teriors OF the power plant buildings
are to be Of reinforced concrete and
the erection Of forms has already been
started on one end Of the engine house.
The multiple reinforcing plates for the
boiler house roof are also in place ana
the concrete filling VIII be poured dur
ing the week. The foundations for the
turbo- generator were poured during
the week, as were those for the two
retaining walls on the oil storage
bench. Two auxiliary p foot concrete
oil tanks that are TO be used for meas
uring purposes are nearly completed.
Each VIII have a capacity OF $500 gal
Ions
Shelter Being Erected
Because Of the fact that the new %
ton Stag pots, recently received, are not
designed for fast haulage around sharp
curves, the idea Of obtaining Stag from
Globe for the reverberatory bases has
blast furnace obtained from the Old
the furnace site so that the Stag can
be made as required The furnace will
probable be ready within a week and
the foundations viii be poured IS soon
as possible. as this work is already
far behind.
