10 the San Antonio LIGHT.
The liXiviation process of treat
ing ore is a modern discovery, and
was first put into practical use in
1858 by Won Patira, native of
Joachimsthal, Bohemia.
The extraction of chloride OF sill
yer with hyposulphides Of lime
was first introduced in America in
1868 at La Dura Sonora, Mexico,
by DR.. T. c. Mills, now citizen of
Monterey, Nueva Leon, Mexico.
THE LIMITATION PRESS Is AS FOL-
LOWS:
The ores are crushed dry, and
then passed through schreens of
% to 80 meshes to the inch. They
are then roasted with salt in a fur
mace. To ascertain the amount of
chloride of silver at the end of the
roasting, it is necessary to make
two allays.
About two ounces is taken out
of the furnace and allowed to cool.
They are then divided into two
equal parts by weight and one
(No. y prepared for the fire allay
as usual. The other one (No y is
introduced carefully into a small
filter in a glass funnel. The filter
ing paper must project at least one
inch above the ore. A solution Of
hyposulphite of soda is then poured
over the ore in the filter, and this
is continued as long as precipi-
tate is obtained on adding sOlu-
ton of sulphide of sodium to the
filtered liquid. This is best tried in
a clean glass tube. If after filter
ing or bathing, the addition of sui
phide of sodium to the bath, does
not produce a precipitate, or only a
slight one, so that the liquid as
sumes only a little dark color
without losing its transparency,
the assay is backed with warm
water and the filter taken
off, put into a porcelain dish or
like vessel, and dried by applying
heat with an alcohol lamp. The
filter can then be removed and
burned above the sample. When
dry, the ashes of the filter and the
sample are fluXed like the other
ounce, and both crucibles placed
in the assay furnace.
The two assays when ready, are
compared, and the difference
shows the silver which was con-
verified into chloride. If the above
operation is skillfully performed
the result will show 95 per cent.
The sulphide of lime is made by
taking one part of powdered sui
phur, three parts of fresh lime and
twelve parts of water, mixed, and
put into a filtering box. The dark
yellow liquid that pass through
the filter is the sulphide of lime.
The aham "horn boiled down" is
the process of liXiviations. 1t is
so simple that any man should be
able to treat his own ores at the
mines aid thus make big saving
in freight.
Your correspondent is indebted
to DR.. T. C. Mills, of this city for
much of the above. The doctor has
been for over 80 years engaged in
mining in California and Mexico,
and is one of the best mining eX-
perts in the country.
In our next letter we will give an
account of the smelling process.
AS there are three smelters in the
city we will pay them a visit
and get a detailed account of their
method of treating silver, lead,
gold, copper and iron.
After that we will give an
account of the mines that pay, and
those that do not pay and why
they do not pay, and how the
money is thrown away.
THE MONTEREY WIRE NAIL FAC
TORY.
Last Saturday morning your
correspondent paid a visit to the
"Fabria de Clavos de Alambre dc
Monterey" or, the Monterey Wire
Nail factory. This factory is sit
uated a mile and a half north o.
the Monterey and Mexican Gul
railway depot, and half mile
lToLn UuSSeuneliHs SinelIeT.
When we reached the office w,
found Mr.. A. r. Bushnell il
charge, and, after stating our mis-
sion, he kindly conducted us to tn
factory, which is close by, ant
where we found Col. Fred. G. Burg
dorfer, the general manager, wit
his sleeves rolled up, giving in
structions to some of the men, hoy
to regulate some new machine
that were recently set up.
The factory is 50X240 feet, tw
