This mineral found in Greenland, which belongs to Denmark, is quar- ried from the mines by the »Kryolith-Mine og Handelsselskab«, (The Cryo- lite Mining and Trading Co., Ltd.) under a State concession. In close connec- tion with this Company is the factory »Øresunds chemiske Fabrikker« in Copenhagen, which has been given the technical use of this valuable mineral. During the last years 5 to 6000 cubic metres of cryolite have been quarried. The export from Copenhagen of cleaned cryolite went up to about 10,000 tons in 1913; but besides there is a considerable export direct to America, which does not come in under the Danish trade statistics. Cryolite is specially used in producing aluminium, enamel and alabaster glass. Øresunds chemiske Fabrikker. (T. »Øresund«), 84 Strandboulevard. Copenhagen.
