the United States bureau Of
mines in charge of the expert
| mental statione in connection
with the state university at Moscow,
win leave tomorrow morning, having
spent more than two weeks in the dis
trict, His purpose sin coming to the
Occur dAlenes at this time was to
make a preliminary Investigation of
the prevailing milling methods, learn
something of the difficulties with which
the mining companies have to contend
in the recovery of mineral values and
later undertake to solve the problems
through experimental tests at the Mos
COW station. Mr.. Wright devoted
several years to this class of metallur-
gical work in the Joplin district and
afterwards was in connection with the
Salt Lake station, from which he was
transferred to Moscow. 1t will be nee
essary to make numerous changes In
the equipment of the Moscow station
before much can be accomplished in
the way Of experimental work. This
will require probably two months. In
the meantime. Mr.. Wright will visit
other mining sections of the state, in
order to be in position to bring the
work of the station in touch with the
mining industry of the state generally
in orderd hat the benefits of its work
may be widely shared.
Likes the coeur d'Alenes.
Mr.. Wright expressed himself as
greatly pleased with the reception ex-
tended him by the mining operators OF
the district and the mill superinten-
dents with whom he was brought in
contact. Every courtesy was extended
him in his inspection Of the mills,
showing that the companies were
thoroughly interested in the work he
was here to undertake. Mr.. Wright
visited every mill in the district and
gained a very definite idea of the re-
suits Of their work. Taken as a whole
he was impressed with the high stan
dard of efficiency in the milling opera
tons Of the district. At the same
time he found some very interesting
metallurgical problems, the solution Of
which he is eager to undertake, and
which when accomplished will make
material increase in the percentage of
recovery. Compared with milling op-
erations in other mining districts with
which he is familiar, Mr. Wright says
that results achieved here make very
favorable showing. Many of the COM
panies are constantly experimenting
for the purpose of reducing losses, and
in all cases his assistance will be well
come and he will be given cordial CO.
operation in his work.
Plan of Operation.
When the equipment of the station
at Moscow is complete and ready for
service liberal samples of ore will be
shipped from the various mines for
experimental work at the station.
These samples will be large enough to
make the tests practical and the var
ious mining companies have agreed to
furnish them as required. Having
accomplished the desired results
through thorough tests at the expert
mental plant, Mr.. Wright or one of
his assistants will come to the dis
trict and try out the improved process
in one of the mills.
Experiments will also be made in the
treatment of ore SO low grade that
it does not yield a profit under pre-
sent methods, and complex or refrac-
tory ores for which no successful
covered.
