or a mailman" IL was not d1nlcuit Tor
, anyone with Frank Elmore's mechanic
cal ability TO design suitable apparatus
in which to carry on the process as a
continuous operation.
In a paper describing the Gilmore
} process that C. NJ Rolker read before
the Institution of Mining and Metal
! lurgy in April 1900, he said: 1.-THE
} mechanical contrivances brought into
faction by the inventor are excellently
adapted to the work demanded, and
bespeak very careful thought, as we'll
as patient systematic, and highly in
telligent work Seemingly insuperable
mechanical difficulties in the initial
stage have been very ingeniously over
come, and the process has arrived at
a practical working stage"
Now while the industrial plant at
the mine before mentioned continued
to work successfully and give increas-
ed confidence as to the future of the
process as a result of the trials on
bulk parcels of ore from other mines,
Wernher, Belt & Co. Mr.. McDermott,
and the brothers Elmore formed a pri-
vate syndicate in which they were
the sole shareholders for the purpose
of carrying on the development and
Introduction of the process. That
syndicate hung out its sign early in
the year 1901 at a demonstration
works in London which was equipped
with a complete crushing mill and
full size working unit of Gilmore plant
having a capacity of rs or 80 tons of
ore per day. to which was shortly
added another unit. bringing up the
capacity to, say, SO or go tons per
day, This works was maintained with
a large staff and was open to all in
terested to see the process In practical
operation. The visitors book contains
the names of most of the engineers
and metallurgists of note, resident in
this country or visiting from abroad
1t was situated in the east end of
London and was so popular as place
o. pilgrimage for professional men
: urgieal Mecca"
A conservative estimate compiled
from the works records shows that
during the period 1901 1915 some $500
to 5000 samples of ore from different
mines in various parts of the world
were tested on a small scale and
about $50 bulk parcels of ore varying
from to 100 tons each We're treated
under working conditions in full-size
commercial unit of Gilmore plant.
1t was in the year 1901 that the
syndicate first issued literature de-
scribing the process and calling atten-
ton to it's possibilities About so
different pamphlets in seven different
languages were published and widely
distributed--to the extent of about
125,000 copies 1t is probably true to
say that in practically every mining
country in the world the technical
press contained articles describing the
process and indicating possible lines
of application.
The process was Investigated both at
the demonstration works in London
and in the working plant at the mine
on behalf of intending users by num-
Der of well known Independent en-
gineers. The result of this propagan-
da was that up to the year 1904 about
80 units of plant which had been sup
piled to ten different mining com
panies. The aggregate capacity of
these 80 units was, say, 100000 tons of
crude ore per annum. They were APP
piled to ores containing copper, pyrite,
gold with iron pyrite, copper GOLDFISH
yer, telluride of gold, and silver-lead
ore.
have elaborated this part of my
narrative because the period | am now
dealing with is the turning point in
the history of this now great industry.
] am DESTROYS of emphasizing that
prior to Frank Elmore IN 1898 nothing
practical or commercial had been ac-
compished, that by his fortunate dis
covery of the selective action of oil |
in the presence of large quantity of |
water success was Immediately achiev-
ed This is proved as shown above
by the investigation of independent
engineers and by the large commercial
installations made. Moreover, it is
accumulated in a remarkable way by
the fact that every flotation plant in
operation at the present time is char
acterzed by the use of large quantity
or water with the crushed ore.
ITO be concluded next week.
