- Abstract
- This paper introduces the recycling technology of cadmium of the output of the bottom blowing furnace in the process of oxygen enrichment of lead,and the process of water leaching,neutralization and sedimentation and so on,the lead and cadmium are enriched.The result showed the extraction of cadmium is 88.51%,the recovery of cadmium is 88.47%,the hydroxide cadmium contains of 70% Cd or more.
- Keywords
- Bottom blowing furnace soot; Water leaching; Neutralization and sedimentation; Hydroxide cadmium
