Abstract

The problems of the processing of sulfate lead industrial products containing noble metals, which are related to lead reduction after partial sulfidizing in an alkali melt at ~600°C followed by the extraction of the present noble metals to molten lead, are studied. The process provides deep recovery of lead and extraction of noble metals.
