Abstract
Most published methods for the determination of platinum and associated metals are not of general application to ores and concentrates, and their accuracy as applied to unknown material is in many cases seriously open to question. The methods here described are chiefly based upon experience with the products of the Sudbury area, but are believed to be applicable without substantial modification to all sulphide ores of nickel and to smelter and refinery products derived therefrom. Methods of concentrating the platinum metals are described, an outline is given of an approximate method of determination based on sulphuric acid parting, and details of a more reliable method in which nitric acid is the parting medium are set out. The results obtained are compared with those of Beamish and associates on similar material.
