Hydrometallurgical Process and Economic Evaluation

In our study, we developed and described a complete hydrometallurgical process including the recovery of Zn by electrowinning and Mn by precipitation from alkaline battery powder. The Metal recovery is the final step in a hydrometallurgical process. Metals suitable for sale as raw materials are often directly produced in the metal recovery step. Sometimes, however, further refining is required if ultra-high purity metals are to be produced.Hydrometallurgy chemeurope

An Innovative Hydrometallurgical Process for Recovery of

This paper describes an innovative, four-step, hydrometallurgical process for gold, palladium, platinum, selenium, and bismuth recovery and refining. The combination of Au → Pd → Se → Bi in series is attractive for applications in major copper refineries where a fully hydrometallurgical process is chosen for anode slimes waste copper slag. This process is simpler than conventional pyrometallurgical process as the addition of any external collectors are not required.47 Hydrometallurgy Metal separation and recovery using hydrometallurgical processes have lower capital cost and environmental impact than pyrometallurgy, and oﬀer greater scope for selective metalChallenges and opportunities in the recovery of gold from
