ing informed regarding the enormous ad-
vantages that exist here for the reduc-
ton of ores and refining Of metals. There
is vet much for the world and for the
people here to learn on the subject, but
it is gratifying to know that the light is
beginning to break.
As a statement of plain facts concern
ing the great Boston & Montana plant
here the following from the New York
Engineering and Mining Journal is of
decided interest:
THE works of the Montana Smelling
company at Great Falls, Mont, we're
planned by Mr.. A. Eilers. Theirgeneral
arrangement differs very much from that
of the two works previously discussed.
In the latter the longest extension is
parallel with the row of furnaces; at the
Montana works this is reversed. A strik-
ing feature is the extensive roasting
plant with its sc parate ore yard. A
study of the plans will show that great
attention has been given to the handling
and storing of large amounts of ore. Tn
loaded cars, arriving On the man track,
are weighed on track scales and then
switched off on side tracks, which lead
to the crushing house and sampllng
works, to the bins for sulphide and car
Donate ores. At the sampling works all
ores requiring crushing are received, and
the sulphide bins are filled with concen.
trates, which are sampled by fractional
selection while they are being unloaded.
The lower bins are for ores, sampled in
the same way, that 20 straight to the
blast furnace. Track No. ! brings the
coal for tho boilers and takes the base
bullion produced in the blast furnaces.
The crushing house and sampling mill,
which is fitted up with the necessary
machinery for crushing, samplipg, and
grinding. delivers the sulphide ores over
d tramway to their respective bins.
"In the rooster building is room for
twenty calcinipg furnaces and fusing
furnaces. They deliver their gases lnto
two parall ! flues running along the cen
ter of the building. These are built one
against the other and are combined into
Il pain tlue after they have received
the gasses Of the single furnaces. This
passcs out Of the building aud terminates
in ii series Of dust chambers connected
with the stack 10y a small iiIe. The
tramways are for carrying ore, fuel and
ashes. The floor of the rooster building
is on the same level as the top Of the
lower ore bius, the roasted ore can thus
be easily discharged into them.
"The Dlast-furndce building has three
floors instead of two, as is usual. The
upper ore bedding iioor is on the same
1aval nc tln hpttnn, ,f thn ki,c for aur-
Donate ores. From the beds made on it
the ore mixture is dumped on the feed
floor neal the single furnaces, where the
charges are made up. The ~tluxes, ar
irving on track No. ., are passed through
the crusher, if necessary; the fuels ar
rive on tho same track. Or the furnace
iioor is room for five blast furnaces. The
furnaces face toward the river, where
the ground is high and furnishes an am
pie Stag dump. The furnace gases pass
through a wide tlue back of the furnaces,
leading into a series of dust chambers
which are connected with the stack.
The ventilation Of the furnace floor
is the one strongly recommended by
Eilers. 1t consists IN allowing the feed
floor to extend only TO the front of the
furnaces and closing it off from the en-
tire front part of the building by
( wooden partition. which siants hack
ward to the ridge pole OF the roof. Thus
i hood as long as the furnace building,
AID having a width Of about IL it.,
teaches from the lowell of the feed floor
to the ventilator and draws Off all the
vapOrs and smoke from the tap-hoie,
the Stag pot, and the lead. well. \ SINH
Lar arrangement at tho smelling works
in Ciaustnal, Prussia, was very clica
clOus IN removing the danger Of lead
poisoning, winch had previously been a
common thing
No well informed person doubt that
the results which will he obtained here
will lead to the final location of all the
principal reduction works of the state
at this city. 1t is already proven that
il would be a business proposition for
tho various companies to abaudon their
present locations and come here where
all the conditions of fuel. water. etc.
are so favorable, One years experience
nf the b. IL Vi. will demonstrate these
advantages in a manner 10 settle all
doubts on the subject.
