Abstract

292,832. Anthoine, R. Nov. 7, 1927. Dry processes of extracting tin. Low grade ores, especially cassiterite in a widely disseminated form and in which the particles are so microscopic that concentration by gravity gives no result, or wherein, for example, the presence of quartz in the gangue prevents the separation, are treated with a reducing gas, such as lighting gas, producer gas, or coke oven gas at a temperature between 300 and 900‹ C., and are then concentrated by a flotation process.
