Using the electrochemical-oxidation products of bituminous lignite tar in the flotational enrichment of high-ash coal slurry

Resumo

The products of electrochemical destructive oxidation of bituminous lignite tar are considered for use in the enrichment of high-ash coal slurry. In particular, their flotational activity in enrichment is assessed. The low-molecular compounds formed in oxidation have surfactant properties. That facilitates the separation of the combustible coal mass from the mineral component.
