MODES OF
Separating Gold andits Localities

Having finished the routes, | now proceed 10
| give description of the most eligible modes OF
separating the gold. Gold, when in place, is usually
found in quartz, between two layers of talcose
slate, but volcanic action is agent powerful,
and its freaks so singular, that no regular theory
will apply to such regions California may be CON
sidered continue ion of the Peruvian range, and
could we reach the bottom of the Pacific lying be-
tween the two countries, we should find it rich
in metallic wealth either of the two. In 1870,
piece of gold was found weighing As pounds, in
Peru. At present, 500 men employed in mines
near the River Pyschma, where the gold is found in
thin plates or leaves, and in spongy nests, as well
as small masses, exactly like the California speci-
mems. If 100 pounds of sand contain "a grains of
gold, it is worth working In Africa they yield 60
grains. Some Of the Georgia ore is worth only
IS cents the bushel yet is worked up in the stamp
ing mills, The same quantity of California earth
yields 2 to 4 or more ounces The specific gravity
of gold is 1860 to 1000 Of water. 1t is more gen.
orally found native than any other metal, but alloy
ed with silver, copper iron, sometimes all three.
In its regune state it is in angular crystals, COM
posed Of yellow octohedrons irregular masses,
and it has been found in cubes in Pennsylvania.
1t is found sometimes in limestone or hornblende,
and also in pyrites, forming probably sulphuret
OF gold The cOmmencent of John {. CalhOuns
Ene at Dahlonega, in Georgia, yielded $4,000 to
the bushel, but it was only depose on the top of
hill, and soon ceased to yield profitably. DIR.
Slngleton's mines have yielded from SO to 100
bustle and more, but are not now SO rich In North
Carolina, the prevailing rock is argiffe, but much
is in matrix of quartz, accompanied with decom
posed iron pyrlles copper, maachltes, etc. In South
Carolina, it is much the same, except at Blacks
mine, where it is found in veins in white quartz,
very pure. The average of the California gold is
2la carats, and worth 80 cents the pennyweight or
SlS the ounce. Pure gold is worth 81 OF the
heavyweight or $50 40 the ounce. The vast guam
tity of quartz, which is the chief matrix in which
the Georgia and North Carolina gold is found is
grand obstacle to It's extraction, especially by smeit
ing-though this has been attempted by Mr.. Bis
sell OF Charlotte, North Carolina, who visited Hun
gary, etc., to inspect the European methods, the
mairix being so different-the Hungarian being
acose slate, like the virgin mines-he did not, I'M
fortunately, succeed, and was cut off by death in
the midst fhis valuable experiments. His brothers,
however, continued them with some hopes Of sue
cess In Georgia, DIR. Singleton and others have
subscribed fund of $4,000 as a reward 10 any
one who will devise an improved method of sepa-
rating the gold. | would suggest TO these gentle
trial of the following: Roast we'll the ore,
and by pouring cold water on, it will split up in
smaller pieces Then heating well large rever-
beratory furnace, add quantity of alka to make
glass with the quartz in cast-ron kettle or shell
Of oval shape and considerable size to cover the
whole bottom of the furnace. When vtrlfed by
rakng occasionally with iron rakers to stir it up,
which is necessary, gold will be discovered adher-
ing 10 them then by laying in iron bars and stir
ring occasionally with wooden poles, which in
creases the combustion, the whole of the gold may
be expected to preclpltate and the glass can be
used profitably in the manufacture of coarser or
finer glassware, according to The purity of the mat
rix 1t iron is found to be mixed with the gold, dis
solve it out with ulphuric acid diluted Lead for
