Includes bibliographical references (p. 16-18). "Tantalum and niobium have become important metals with a variety of metallurgical uses. They are in short supply on a world basis and as demand is certain to increase, it is in Canada's interest to search for and develop additional resources. The purpose of the present report is to encourage this. It describes the properties, uses and resources, both domestic and global, and gives production and consumption statistics for both metals. The report has two appendices consisting of brief reviews of ore dressing investigations related to the mineralogy and concentration of Canadian ores conducted at CANMET; it also covers research on foreign niobium ores considered to be of interest in treating domestic ores. The summaries consist of brief descriptions of the mineralogy and analyses of the ore samples tested, state the purpose of each investigation, the methods of concentration, results obtained, and conclusions. They also offer recommendations for future action"--Abstract, p. i. Includes abstract in French. Tantalum Niobium Tantalum ores Niobium ores Ore-dressing Noblitt, H. L. Canada.
