THE NEW ROBUST MILL.
Built on Modern Lines and Prac ii
cal in Every Particular.

The Robust mine, originally the
property OF p. c. Weber and others,
was taken over by w. r. Lynn of
Salt Lake City, during August 1893.
A stock company was organized, Mr..
Lynn becoming the treasurer and stock
issued the following October. Since
that time the history of the mine has
been an active and aggressive one.
During the Spring of 1900, the build
ing of mill for the purpose OF handling
the extensive ore bodies, then blocked
out, became serious consideration.
The following summer contracts were
let, and the construction commenced
in August OF the same year, two years
after the formation of the company.
At this time the question OF water be-
came prime one. A well was sunk
about half mile above the present
site of the mill, pumping plant in
stalled and pipe line laid TO convey
the water to point above the mill.
This mill, the subject of the present
sketch, is now nearly completed and
It is expected win start crushing by the
18th OF the present month.
The plant is essentially dry crushing
affair. The ore will be delivered at the
mill from the new tunnel, just com
pleted, connecting the. old workings
with the surface. Here il will pass an
Austin Gyrotary crnsher going to the
main storage bin, having maximum
capacity OF l50 tons. From this Bin
it is fed through an automatic feeder
to the revolving drier, discharged into
pit and elevated by a Sprocket Chain
elevator to the primary or roughing
rolls. II is then elevated by means OF
an ordinary bucket elevator to the
rotaay screens. These screens divide
the product into three sizes, the finest
going to the finished bin directly un-
derneath, the next in size to the finish.
/ ing rolls, thence to be elevated and
rescreened, and the coarse to the
secondary rolls. This also being ele-
vated and resereened. The pulp or
finished product. leaves the finished
bin To fall by gravity through chute
into the charging ears. The cars
stand directly over pair of Howe
platform scales. Here the pulp is sam
pied and weighed. The ears are run
to the teaching vats, over two lines of
trackage, paralleling each other the
entire length OF the vat room, some
| l20 feet, and here discharged.
In the watts the pulp receives its
treatment, which Is to be some form or
modification of the Cyanide process at
present in vogue. The gold bearing
solutions, leaving the teaching vats,
are conveyed by means of launders to
the precipitating department, where
the values are extracted. The tailings
are discharged through four circular
discharge doors in the bottom of the
yats, falling into ears below, and are
then run to the waste dump.
This mill is built on the gravity plan
and IS calculated to be as nearly au-
tomato as possible. The maximum
capacity is figured at 80 tons, this
being the estimated vat capacity. 1t
is an excellently well constructed affair
and much credit is due Mr.. Atkins,
the mill-wright, and his able assistant,
Mr.. Harris, for the fine results OBJ
tanned,
In conclusion, we will say, that the
mine has large ore reserves. The mill
is built on practical lines and with
a practical and thorough chemist at its
helm, Mr.. w. II. Wickham of Denver,
Colo, the stock kholders should expect
excellent results.
