Overview

Excerpt from Report on the Molybdenum Ores of Canada, 1911 Molybdenum was discovered by Scheele towards the end of the eighteenth century; but it was not isolated from its compounds until some time later. The pure metal is white in colour, and very difficult to fuse. Like iron, it takes up carbon, and the carbon-bearing alloy is more easily fused, but very much harder. Until recent years it was little in demand for industrial purposes, and very little search was made for deposits of molybdenum ores. At the present time, however, owing to its introduction into metallurgy in the form of iron-molyb denum. Alloys, there is considerable demand for such ores, which are produced only very irregularly, and in small quantities. If a larger and more regular ore supply were assured there is no doubt that new uses would be found for these alloys, and the demand for the ores would increase. The present report embodies the results of observations carried on during the field seasons of 1909 and 1910. By presenting in one report all the informa tion available regarding the molybdenum deposits in Canada, it is hoped that a new interest may be awakened in the possibilities of the Dominion as a molyb denum producing country. At present this information is much scattered; the observations were made by a large number of persons, and some of the deposits have not been examined for many years. Recently a new value was imparted to all molybdenum properties owing to the demand for ores of this metal for the manufacture of steel alloys. Deposits which had no industrial value a gener ation ago may now be regarded in a different light. The objective of the writer was, to visit and examine personally as many as convenient of the prominent molybdenum deposits in Canada.
