Valuable work is now being done
TO demonstrate the applicability Of
this basic principle Of cyanide meth
ods. extending not only TO the econo-
mic dissolution of gold and silver,
but also to all the metals usually as
soelated with gold and silver, particu-
larry copper, lead and zinc. By this
modern method, control of operation
is mastered, and an unusually high
recovery of all the metals in refined
and marketable condition is obtained
by substitute precipitation or by
electrolysis Even this recovery APP

nide method is in the recovery of
gold, and just ss inexpensive-con-
ditions which have been brought
about through almost complete re-
generation OF the gas used, darable
apparatus, and simplifed manipula-
tlon.
The high state Of perfection to
which this art has been brought may,
like the cyanide method, be credited
TO many inventors covering a period
of many years, but the recent work
of John l.. Malm, of the Western
Metals company of Denver. is entitled
TO the distinction of simplifying and
perfecting the mechanical manipula-
tion, which now promises to bring
the method within the range of eco
nomic operation.

town. Colo, for the treatment of the
difficult ores of that camp, is about
two-thirds completed. A careful ex-
animation of the strong but simple
installation of that unique plant sug-
gests that a practical solution of our
difficulties in successfully handling
complex. rebellious ores is nearing
completion, and that the day is not
far distant when such ores will be as
eagerly sought as the straight gold
ores, and will prove quite as profit
able.
Under the method used, no one
metal IS sacrificed in order to save
another. but all the metals Of com
merce in the ore are saved, barring
slight mechanical loss that can not
be prevented in any operation how
ever perfect il may be. II this be
not perfection, it is at least the high
est point that metallurgical skill has
reached in this field Of operation,
and its value and importance are
difficult TO estimate. The compile
