ORES REDUCED AT A COST OF
ONE DOLLAR PER TON.

tically tested in New York city, is de-
seribed by the Mining Record, as follows:
Our attention, as mentioned in our
last issue, have been called to the method
OF extracting gold and silver from ore,
patented by Walter Hamilton the well
known assayer, and mineralogist of this
city, we took occasion to visit the extern
sive works, now about completed, at the
foot OF Fifteenth street, North River, our
purpose being to determine for ourselves
If this was really what was claimed for
| it. viz:
THE GREATEST INVENTION OF THE cKN-
FURY.
We found large substantial building,
80 feet by l75, containing the most per.
feet and complete plant of the kind we
eyer saw, having everything necessary
for the thorough treatment of any class
OF ore containing gold or silver, at the
rate of at least 1000 tons per day. Up.
ON entering the building we were met by
MIR. Hamilton, who kindly accompanied
us through the works and explained the
working of the different parts of the ma
chimes, and demonstrated to our entire
satisfaction the perfection to which he
has brought his process. The first thing
that attracted our attention was the
arrangements for crushing and pulveriz-
ing the ores as they arrive. These
crushers reduce the ores to fine powder,
which is then taken by means of an ele-
vator and emptied into the hopper of the
roasting and desulphurizing furnace.
This furnace is
THE ACME OF PERFECTION,
Being under the most perfect control in
all its parts as regards the control of heat
and regularity of feed, which is automat-
ic, and in case Of arsenical of sulphureted
ores, volume of gas is introduced that
completely changes the gases as they are
eliminated from the ore, which is de.
livered at the end of the cylinder per.
fectly desulphurized. From the roasting
furnace the ore is taken by another ele.
vator into what is called the vacuum
furnace, where it is passed through a
bath OF melted lead. This part of the
machine is so constructed that the ore is
held submerged in the molten lead and
automatically distributed about in such
manner as to insure every particle of
ore coming in contact with the lead, then
escaping, the tailings are carried by a
conveyer to the dumps. This process of
reducing ore is
BASED UPON THE ESTABLISHED FACT,
Recognized by all smelters and assayers,
that gold or silver, when heated to the
proper temperature, have much strong
er affinity for molten lead than for quick
silver, and becomes instantly taken up
by the lead upon contact. One great ad.
vantage that struck us in Mr.. Hamilton's
process is, that from the time the ore is
| put into the crusher until it is dumped
on the pile for tailings, it is not once
seen or handled, thereby saving great
amount of labor. Another point is the
economy in fuel, it requiring very little
more than would be used in running a
steam engine, and on the point of econ.
omy these works are fully capable of
working 100 tons per day, and we can
not see how it is possible for it to cost
SlOO per day to run them; Consequently,
Mr.. Hamilton's assertion that they can
WORK ORE FOR ONE DOLLAR PER TON
Not only seems proven, but to us appears
to be an over-estimate of thee This
process has been taken up and is about
to be put before the public by company
OF practical men of large experience in
mining, and who have started with
capital. They have spared no time or
expense in the erection of these works,
and the result is as near perfection as
is possible. We are authorized to say to
any one who is personally interested in
mining and desiring to reduce the cost Of
milling their ores, that they are invited
to call at the office of the company, room
Al, No. 2 Wall street, where Mr.. Henry
Cummins, the President, or Mr.. H. E.
Fanshaw, the Secretary, will be pleased
to furnish any information required, OF
they are invited to send their ores to the
Works at any time after the lst of Oc
tober, and have a practical demonstration
Of this certainly wonderful machine, il
quantities not less than five tons. AL
though perfectly satisfied ourselves o.
the perfect working of the Hamilton pro
cess, we shall from time to time publish
in our columns for the benefit Of the pub
