vi. mining and metallurgical industry.
The total iron ore export of Sweden up to 1910 inclusive was:
Iron Ore low or moderate in phosphorus........ 1 706 000 tons
» > rich in phosphorus from Central Sweden . . . 11 315 404 »
> > » > » > Norrbotten, circa ... 27 623 400 >
Total 40 643804 tons
The ore export from the ore fields of Lappland as well as from the export
field of Grängesberg has been, owing to the agreements concluded in 1907, 1908,
and 1913 between the Swedish State and the companies who own these fields,
(Luossavaara-Iviirunavaara aktiebolag, Aktiebolaget Gellivare malmfält and
Trafikaktiebolaget Grängesberg-Oxelösund) restricted for the period from 1908 to 1932 to
exclus. the ore which is obtained by concentration from the gangue (varp),
that is, the ferriferous röck which falls away in the extraction of the ore or
which has to be extracted in order to get at the ore, but which is too poor to
be available in its unprepared condition for export. In connection with these
agreements the State became a shareholder as to half in the
Luossavaara-Kiiruna-vaara aktiebolag and the proprietor both of the Luossavara, the Mertainen, the
Ekströmsberg and other mines and also of the Svappavara and Leveäniemi
and other iron ore deposits in the län of Norrbotten, though with the proviso
that there should be no export of ore from these fields prior to 1932. The
State receives for this a royalty, calculated according to various considerations,
on every unit quantity of ore raised, and has the right to buy in all the shares
in the companies in 1932, after a valuation of them has been made. .
Sweden is comparatively poor in ores other than iron ore. At present
the only ores mined are zinc, lead, copper, manganese and iron pyrites.
Thus in 1913 10 013 tons of zinc ore were extracted in 4 mines, 3 924
tons of copper ore out of 6 mines, 215 tons of lead ore in 2 mines, 107
tons of manganese ore in one mine, and 34 295 tons of iron pyrites out of
one mine. The aggregate value of the said output amounted to 1 008 805
kronor. Besides this, there were obtained by concentration 40 739 tons
of zinc concentrates, 3 007 tons of lead concentrates, 1 534 tons copper
concentrates, 3 894 tons of manganese concentrates, and 24 tons of iron pyrite
concentrate, with an aggregate value of 2 495 623 kronor.
The biggest and most important deposit of zinc ore is that at Åmmeberg in
Southern Sweden with a length of about 5 kilometers and with a breadth which
in places reaches up to 12 meters. Other deposits of zinc are those at
Kavel-torp, Saxberget, Stollberg, and Sala. In all these deposits the ore mineral
consists of zinc blende, frequently commingled with lead glance and copper pyrites
and it is from these mines that the above stated quantities of lead ore have
been yielded.
Copper ore is mined at present only in the Falun Mine, where however, the
output of copper ore plays a very subordinate role in comparison with the output
for Kirunavara................ 103100 000 tons
» Gällivare................ 30 650 000 »
> Grängesberg............... 13 250 000 ■
Total 147 000 000 »
