Computer system for optimizing a uranium extraction process

A computer system has been developed to optimize the metallurgical process of a plant. The system includes models of the grinding and leaching sections, of the continuous ion exchange plant and of the solvent extraction plant. Based on analytical assays of five chemical elements and on the costs of water, electrical power, chemical reagents and other major consumable items, the system can perform mass and volumetric balances and can provide information which permits making operating decisions to optimize the performance of the process as a whole. This approach is superior to that of optimizing the operation of each individual section. (author). 5 refs, 7 figs, 1 tab
