INVESTIGATION OF HYDROMETALLURGICAL SYSTEM ACID LEACHING MEDIA

摘要

Modifications to the acid leaching media employed in the recovery of uranium from halide-contaminated scrap residues have been developed from laboratory data and have been demonstrated in the National Lead Company of Ohio Metals Recovery Plant. The conservation of acid and hydroxide values is effected by acid recycle and high-pulp-density leaching techniques which have been devel¬oped. To enhance economic gains and to improve processing conditions, sub¬stitution of an alternative mineral acid and an alternative oxidizing agent has been considered.
