Lappland.
Output and Export of Iron Ore.
The annual amount of iron ore mined in Sweden during the last
decades figures out as follows:

1841-50 .... 270 000

The output of ore in Sweden for 1912 was 6 699 226 tons. As the total
output for the world in the same year may be computed at 157 million
tons, it follows that Sweden’s contribution was about 4-3 %.
Table 44 gives a conspectus of the relative share taken by the different
provinces in the output since the beginning of the nineties of the last century.
Thus, out of the ore at present mined in Sweden about 65 % fall to the
Norrbotten mining fields and about 35 % to the mining districts of Central
Sweden, out of these 35 % about 19 % proceed from Kopparberg Ian, 7’6 % from
Örebro län and 4"6 % from Västmanland län.
Over 69 % of all the prime ore produced in the course of the year 1913
exhibited an iron-content of between 60 and 70 the bulk of it was produced
in the big ore fields in the län of Norrbotten and at Grängesberg in
Kopparberg län. Further 82’9 of the annual output contained at least 0"i % of
phosphorus, the bulk of which came from Norrbotten län and Grängesberg, whereas
the ores of Central Sweden were mostly poor in phosphorus, having a phos-
