METHOD FOR RECOVERING HEAVY-METAL FLUORIDES Russian patent published in 2006 - IPC G21F9/30 C01G43/25 

Abstract RU 2275705 C2

FIELD: nuclear engineering.

SUBSTANCE: proposed method includes mixing of heavy-metal fluorides with reducer free from hydrogen atoms and fluoride-binding component. This is followed by heat treatment, and aerosols produced in the process are cooled down followed by their separation into solid and gaseous fractions. Reducer incorporates fluoride-binding component in the form of carbon, sulfur, volatile metals, and their acid-containing components.

EFFECT: facilitated procedure and enhanced effectiveness of process.
