The Oxidation of Sulphur Dioxide and the Formation of Sulphuric Acid in Situ at Atmospheric Pressure in the Leaching of a Uranium Ore
The oxidation of sulfur dioxide to form sulfuric acid in situ, at atmospheric pressure and temperatures from 25 to 80°C. Concent 85% C, was examined by passing a mixture of sulfur dioxide and air for 7 hours through a reaction vessel containing quartz- or uranium-bearing solids moistened with water to 85% solids. At the end of the contact period the solution was analyzed for free acid and other constituents in order to determine the extent of oxidation of sulfur dioxide and extraction of uranium. In tests with quartz at 80 un. Concent 85% C, the addition of ferric sulfate or ferric oxide increased the amount of sulfur dioxide converted to sulfuric acid. For example, without ferric sulfate added to the conversion obtained was 2%; with 0.7 and 2.3 lb/ton quartz of ferric sulfate the conversions were 18 and 24%, respectively.
