High-efficiency dechlorination processes are crucial for the clean utilization of CuCl waste residue from zinc hydrometallurgical processes. A new method oxygen-enriched microwave roasting has been proposed to improve process. The cavity perturbation was used in this paper measure permittivity a at various temperatures and apparent densities. results show that temperature had more significant e...

Waste generation is a part of every technological process, including galvanizing. The presented paper deals with the characterization flue dust generated in process hot-dip galvanizing, and proposes possible methods for zinc recycling. released into atmosphere as white fume above bath, which caused by decomposition ammonium chloride present flux. This classified hazardous waste material particl...

Impact of process conditions on product quality is investigated in the recovery high purity (NH 4 ) 3 ScF 6 by antisolvent crystallization.
