Plasmachemical processing of germanium-containing mineral and technological raw materials

This work is a study of the possibility of plasma-chemical enrichment of fly ash. In experiments with a flow reactor, the recovery rate was more more than 99% in slag and 70–80% in unmelted particles. In experiments closed in germanium with the melting of the mineral part of the ash in a reactor with a flowing melt film, an extraction degree of 95–96% was obtained, and the enrichment degree can be estimated as 30–40.
