of iron pyrites have amounted to 500,000 tons per year. In recent years iron ore has figured very prominently, the mines in Sydvaranger having contributed very largely under this head. The mining industry is of great importance also to other Norwegian trades, in that it furnishes a substantial quantity of the raw materials required at home. It supplies, for instance, large quantities of iron pyrites to Norwegian chemical-pulp mills and to the Orkla smelting works for the produc- tion of pure sulphur for export. Again, the mining industry supplies raw materials to electro- metallurgical and electro-chemical works, which represent one of the greatest export trades of this country. This industry now includes also the coal mines in Svalbard, which have been supplying consider- able quantities of coal for several years.
