THE CONCENTRATOR.

THE CONCENTRATOR.
The concentrator building is we'll un-
der way. 1t is to be frame structure,
l3Gx225 feet in dimensions and will con-
tain upwards of 100000 feet of lumber,
all of which is now on the ground. The
foundations are finished and Contractor
Grant is pushing the frame work rapidly,
80 that within six weeks the building
will be completed. The building, shaft
ing and all general arrangements are for
concentration Of 800 tons capacity
(which corresponds with 600 tons smell
| teri and the actual machinery is on the
grounds for GOO tons, daily. With the
great abundance of water at hand the
company has been prompted to put IN
every possible appliance for carrying the
percentage of saving to the highest point
yet reached. The concentration will be
supplied with large number of crush
ers, rollers, hydraulic separaters, jigs, re-
crushers. round tables, f'rue Vanners,
settling tanks, and every appliance pos
sible to carry the savings to high per-
centage. The enormous amount OF free
water at the command Of the company
has induced them to undertake this

desired results. 1t is confidently ex-
pected that when these works are run
ming it will be fully demonstrated that
the miners of Montana can not afford to
reduce their ores al any other place.
However, the company expect to be so
overloaded with their own work that they
cannot entertain the idea of doing Gus
tom work. But the field will be open
for others. The company will purchase
as offered rich silver smelling ores.
| HOW IT WILL BE DONE.
The general process of smelling will
consist of drying, calcining, smelling in
the latest type Of gas furnaces to
matte and pig copper, refining to in.
got and finally refining by the electrolytio
process. producing from the Montana
ores generally known as very base, pro
duct equal to the very best Lake Supe-
rior brands. The facilities of the Boston
& Montana company for carrying out
this process will be as complete and eco
nomical as any the world knows.
THE STACK AND FLUE.
