URANIUM PRODUCTION-PROCESS DESIGNS FOR LEACHED ZONE PLANTS VolumeⅢ. Alumina Recovery Section

摘要

Process designs and cost estimates for two alternate process¬es in which alumina is recovered from leached zone are pre¬sented in this report.nAlthough a very pure alumina is produced in this process, cap¬ital costs and operating costs are relatively high. Efforts are being made to redesign the process to include equipment that would be less expensive and would still give a metallurgical grade alumina. Efforts are also being made to develop pro¬cess changes in the design, in order to reduce operating costs. It is believed that additional laboratory and pilot plant work will bring about a considerable reduction in both capital and operating costs.
