following chapter on manufacture, especially the Chemical industry.
The most important metals, together with the corresponding raising of
ore, are summarized here. Regarding the breaking of fossil coal, it
has already been dealt with in a previous chapter in connection with
reports on the iron mines.
Copper. Next to iron, copper is the most important of the metals
produced in this country. Formerly the production of copper was carried
on in several different places, and at nearly every mine accessible, but
now it is limited to the copper works at Falun, Åtvidaberg, and Kafvel
torp, and of låte years also is carried on at the Superphosphate works
of Helsingborg as an important subsidiary industry, copper (and silver)
being extracted from the waste obtained in producing sulphuric add
from cupreous sulphur pyrites. At the firstnamed of these works, the
ore is mined at the old mine of Stora Kopparberg (Falun), of which
mention is made over 600 years ago. The Åtvidaberg copper works get
their ore from the adjacent Bersbo and Steffenburg mines. Kafveltorp
gets its ore from the mines bearing the same name. The Helsingborg
copper-works, which formerly imported their sulphur pyrites from Röras
in Norway, have of låte begun to take ore from the newly discovered,
vast pyrite deposits near Sulitelma (likewise in Norway). Besides at
these works, copper was formerly produced at several other places in
the kingdom, e. g. at Riddarhyttan, Håkansboda, Virum, Huså, Kengis,
etc., but now the production of copper at these places has ceased, partly
for lack of ore, and partly on account of the low prices of copper. In
all these places, copper occurs almost exclusively in combination with
sulphur, such as copper pyrites, mostly sprinkled into the siliceous
mineral, or in intimate combination with sulphur pyrites. The ores now
worked contain on an average 3 % of copper.
1 Here are not included certain intermediate productions, a number of which **
manufactured in no small quantities, such as, in 1900, precipitate of silver 6,966
kilogram, raw and- autimouious lead 21,709 quintals (à 220-4 lbs.), cement and raw copper
12,263 quintals, as well as roasted zinc blende 267,720 quintals.
