Roasting in an oxidizing environment improves extraction of uranium from some refractory ores. Roasting of the ore tested also tends to reduce reagent costs and handling problems. Ores that may benefit from roasting include those of low uranium extractability that contain oxidizable organic materials or clay minerals. Roasting improves the porosity of ores by removing carbonaceous material and dehydrating clays, and it may even break down agglomerates of a clay-silica-organic nature. The result is better access of the leaching agent to the uranium-containing fractions of the ore.
