ZINC Norway possesses a fair number of zinc deposits, but at the present time only the Mofjeldet mines in Nord-Rana, owned by Bergverksselskapet Nord-Norge A/S, are being worked. In 1932 the output was roughly 81,000 tons of raw ore, giving about 13,400 tons of the marketed product — a zinc concentrate of not above 60 per cent. of zinc. Further, zinc concentrate is extracted as a subsi- diary product at the Sulitjelma mines, where the output in 1932 was 2,600 tons. The production of metallic zinc was commenced in Norway in 1907 at Sundlgkken near Sarps- borg, but these works were closed down in 1930. In the years 1911-1915 zinc was manufactured at Ilens Smelteverk, Trondheim, and from 1915 to 1925 at a smelting works in the J¢ssingfjord. At present only one zine plant is in operation in Norway, viz., Det norske Zinkkompani A/S. This company began working in 1923 and em- ployed 15,000 kw. of hydro-electric energy leased from the Tyssefaldene company. In 1924 the power volume was increased to about 22,000 kw., and new works were built in 1926 at Eitrheim near Odda, for the employment of a licence from the Anaconda Copper Mining Co. The yearly output approximates 40,000 tons, and this plant is at present the largest zinc works in Europe. 90
