URANIUM PRODUCTION-PROCESS DESIGNS FOR LEACHED ZONE PLANTS Volume VI. Ammonium Sulfate Decomposition and Sulfuric Acid Plants

摘要

Presented in this report are process design and cost estimates of facilities for the production of ammonium hydroxide and sulfuric acid. These facilities have been integrated into the leached zone processing plants which produce 450, 225 and 100 tons of uranium per year.nThe process involves the catalytic decomposition of ammonium sulfate to recover the ammonia and sulfur values. Capital costs of the decomposition reactor and auxiliary equipment in the present process design are relatively high. It is believed that revisions of parts of the present process would bring about a considerable reduction in the capital costs. These revisions include redesigning the decomposition reactor and modifying other steps in the process.
