slimes was investigated. The sub-bituminous coal and the meta-bituminous coal have significant differences in their surface …) collector. The adsorption of PAX on pyrite was significant while that on the coal surfaces was negligible. The recovery of … pyrite from sub-bituminous coal increased by 55% when the concentration of PAX increased from 1×10−4mol/L to 5×10−4mol …

Fly ash from the combustion of coal shows potential as a source of valuable metals like the rare earth elements (REEs … experiments with a coal combustion fly ash showed a certain size dependence of the REE concentrations. In the different size … a coal fly ash. …

Nowadays, comprehensive perception of the tar characteristics generated from municipal solid waste (MSW) and coal to …, MSW and coal samples were chosen as principal components. The mixture of these products was pyrolyzed in a horizontal tube … 13C NMR spectra indicated that the functional groups of the tar derived from the mixture of MSW and coal were dominant at …
